I generally explain it this way. I'm disregarding the unknowns of the controller for now. If you change your battery to a larger voltage battery, such as swapping a 48V to a 52V, it's like putting a bigger engine in your car, or adding a cam etc. You'll get a little more power (torque). If you swap to a larger amp/hr battery, such as swapping to a 20ah battery from a 13ah battery, it's like adding a bigger gas tank to you car. Watt hours is how to measure a battery pack's energy capacity. Multiply the voltage by the amp hours of the pack. A 48V, 13ah battery pack has 624 watt hours (48 X 13 = 624). Each mile you travel will cost you between 20-25 watt hours. Therefore a 624 watt hour pack should get you around 25 miles without any pedal assist. Watt hours determine the range of your bike, depending on your weight, the bike's weight, how and where you ride. The range can vary. Generally bigger is better, but it gets exponentially more expensive. FYI, on one of my eBikes I had a 48V x 13ah battery. I never tested the range with that battery, but I usually went from 5 bars on my battery meter to 4 bars after 25 kms (using pedal assist). I believe my range might be around 65-70 kms. I bought a 48V x 20ah battery. Now I go from 5 bars on the meter to 4 bars after 42 kms. Yesterday I went 132 kms and I was down to 1 bar on the meter. I'm pretty sure I can get at least 140 kms on this 20ah battery. So...bigger is better, but more expensive. Your choice.

@@redzepplin7397 Yea something doesn't seem right. Unless you weigh 400+ lbs, which might explain some of it. Since my last comment here's more I found out. With my 48V x 13ah battery using PAS2 most of the time except for short busts to PAS5 when I come to a hill, I can get 80-90 kms (up to 56 miles) and with my 48V x 20ah battery on PAS2 also, I can get minimum 140kms (87 miles). I weigh 200 lbs and I don't carry extra junk around except for a 1.0m chain and lock. The brand of battery might be a factor also. I read yesterday at an eBike forum where a guy bought a no-name battery on eBay that was supposed to be a 52V x 25ah battery and he actually got less range from it than his original 48V x 13ah battery. I have one Himiway Cruiser and another which is a Trinx M500. Both use Hailong batteries. Hailong are supposed to use Samsung, Panasonic and LG cells, so are quality batteries. But you still need to be careful because disreputable aftermarket Chinese sellers can still put a Hailong logo on a shitty battery. Especially with eBay you need to be careful. All I can say is good luck...

You gain a few more revolutions of the motor, but you sacrifice torque. Think of a motor as a seesaw. On one side its speed, on the other is torque. The only way you get more of both is by getting a bigger seesaw. You can increase the speed of the motor, but you'll decrease torque for any given speed. It is unlikely he is making use of the full torque of the engine in his tests so this may even be a desirable outcome. Its still a 500w motor, instead of drawing 14A at peak power. It's drawing 10A.

Where do you come up with "Each mile you travel will cost you 20-25 watt hours"?

Hi there, what you did is called Overvolting. It’s quite a common practice. Modern brushless motors don’t have a fixed wattage. The controller creates and limits the wattage of the motor. If you just connected the battery directly to the brushless motor it would just draw the maximum available current and spin as fast as possible until it over heated and failed, or until the battery exploded. The recommended wattage for the motor is normally based on how much heat the motor can withstand before it starts to degrade. Generally speaking you don’t want the motor getting over 80c. Only overvolting by 12v is usually ok heat wise though, if worried just monitor the heat of the motor with a laser thermometer to be safe. The motors wattage is just the volts x amps (or amps x volts lol) and that’s limited by the controller. Generally speaking though more voltage equals a higher top speed and more amperage equals more torque and faster acceleration. That’s why overvolting by 12v only affected your top speed and not your acceleration. To improve the acceleration you’d need to increase the amperage of the controller by buying a different one or performing a shunt style modification to the controller. You could have a 500w motor controller programed with higher amperage then voltage and it would have lower top speed but higher torque and acceleration, or with higher voltage than amperage for not as much acceleration or torque but a higher top speed and both would still be 500w. In your case overvolting the 500w motor by 12v turns it into 750w (roughly) motor, as long as the controller is rated to allow the full 12v extra. To be honest though, I think your controller is still limiting the volts a little bit as well though or you’d probably get an even slightly higher top speed than you did. That’s also probably why the company said it may burn out the controller faster because most controllers have fixed physical limitations. Usually (but not always, especially with the really cheap stuff) the rated wattage is the nominal power and not peak power so a 750w motor could be drawing as much as 1000ish watts when under maximum load or on a steep hill. Hopefully this is helpful to someone.

Umm...no. There's a lot of "close enough" information here, but there's plenty enough that misses the mark. Brushless motors such as these are 3-phase motors. There are 3 main wires going to the motor; you can't just connect the battery to the motor and have it spin. It reuqires the controller to convert the DC from the battery in to 3-phase, alternating current. Hooking the battery directly to the motor would only use 2 wires and the motor would rotate a few degrees, at most, and lock in place. Since it's not rotating, it would have no back EMF and draw as much power as it could...at which place the BMS on a lithium pack would trip it's over-current protection and disconnect the battery. If there was no BMS, you'd fry the motor windings that are currently active. Don't try it. Increasing battery voltage will give you both more low end torque and top speed. At the low end of things, the coils on the motor are, to simplify it, converting the higher voltage, low current battery pulses in to lower voltage - and more importantly - higher current in the windings. Think of it more like how many watts you're putting in; if you're putting in the same amps, but higher voltage, you'll get more watts. Current(amps in the windings) = torque. You'd get nowhere in a hurry on take-off if this didn't happen. Winding currents are easily 3x as much as battery current. Higher quality controllers will limit coil winding amps to this 3x to prevent over-heating/burning up said windings. A brand-name 150A controller will thus monitor and limit winding current to 450A. I agree that the controller is dialing back the power; the OP should have seen better results. 15mph@ 36v should have seen 20mph at 48v. Perhaps changing the settings to 48v is what told the controller to dial back. I have a folding ebike almost identical to these. It came with an 8 amp controller in it; it wasn't working because the display had gotten water in to it, and, stupid design as they are, you can't use the controller unless the display works. It was rated at 350w, so i tossed in a cheap - no display - controller rated for 350w, but the difference was that it had a current limit of 18A. These cheap controllers will put out the 18A for a few seconds, meaning it's putting out ~650W on take off, and will do it briefly when hill climbing. The rest of the time it will run at half that, 325w. With a fully charged battery (42v), it can out out about 750w. It really scoots around! Totally out performs what I just watched in this video. Yes, the top speed is similar...35km/h....but it gets there in the first hundred feet or so, and will stay close to that up minor hills. With pedalling, it won't drop below 30 except on the steepest of hills. There's a chance that the original controller's "8A" was capabale of doubling that rating, but after watching this, I would have to say that 8A is 8A, period. The controller was half the size of the 18A one I put in. Smaller controllers have higher internal resistances, which will add to the limitations you're experiencing. More MOSFETs will reduce said resitances, allowing for more/better current handling. The 18A controller has 9 FETs in it, the original had 6. Physically it was almost twice as big...it barely fit in the frame with all that mess of unnecessarily long wiring. The 500w/32A/48V controllers typically have 12 FETs, my 800w/38A/48V has 15, the 1500w/45A/72V has 18....and my 3000w has 24 much larger FETs and copper bus-bars; it's a work of art inside. For anyone building their own...bigger is better, when it comes to motors (and batteries). I'm using the 1500w @ 48v, so it's more of a 1000w(2000w peak) controller on a 3000w motor, so you'd expect it to be a bit lack-luster...but the bigger motor is much more efficient/better at making torque; If I don't have my weight over the handlebars, it will wheelie from a start if you give it the beans, and tops out at a bit over 50km/hr, limited by the relatively low wattage. It's also much more efficient at high loads than a smaller motor that is being pushed past it's limits, though it's presumably less efficient at lighter loads. You need batteries that can keep up with your motor or controller, so, honestly, you're better off building a battery yourself if you have the means...it will cost half as much as one that comes pre-built and you can guarantee that it's rated for the power demands you're going to put on it. Don't expect a cheap ebay battery to last long if you're pulling 1500w from it. Don't believe them when they say they have samsung cells in them, either. Expensive packs from well-known ebike brands should be what they say they are, but, again, they're expensive. If you're using chinese cells, stick to Liitokala, and even then, watch for fakes. LiFePO4 cells are a bit more of a pain to work with, but they're also safer and, if you don't cheap out on the BMS, live a lot longer; they're generally also high-drain without the extra cost that you'll get with samsung high-drain Li-ion. So, yes, bigger is better with batteries. I'd advise having a pack with a watt-hour of equal to or higher than your controller's watt rating, so that you get a decent range and can keep up with demand. Even low-drain batteries can keep up if you have equal or greater watt-hours to watts out; they're generally rated at "1C" or, if you're lucky, "3C" - 1 or 3 times their capacity. If you have a 30ah battery, it won't care if you're pulling 15 amps out of it non-stop. Even the 1C cells will be fine at 30 amps in a 30ah battery. I've got 1000 watt-hours worth of cells on the way for a bike I'm building for a buddy, which will probably be run at 800w, but they're 4C, so he'll be able to run more power than the 1500w motor is rated for, if he gets the urge. About $350 US for the cells and a fancy "smart" BMS. As to over-volting...they'll generally take it if you're only really increasing the voltage. Higher voltage will raise your top speed. It will still consume the same amount of power at the same speed you were going before. On my first ebike, which had a 400w direct-drive motor, I put a 1500w controller on it. It sucked compared to my 3000w running at 1000w, but it took it...it would only pull 1200w up a long, decently steep hill, while managing 40km/h, and was only cozy-warm to the touch after, and this was a real cheap turd of a motor. Bumping up 50% power with a 50% voltage increase ought not to bother most motors. Maybe in San Francisco, or if you're climbing over a mountain it will over-heat it, but where you're in reasonable terrain, no problem. The same probably can't be said for big motors that are already running close to their limits, though they tend to have temp sensors to prevent issues. They also sell the exact same motors with higher wattage ratings when coupled with higher voltage controllers. No differences otherwise. As to blowing FETs...yes, if you do a shunt mod wrong, you'll blow your FETs. If you're over-volting, then that depends. The capacitors have a habit of not being rated to take much more voltage, and will generally blow at a lower voltage than the FETs. Both have common voltages they are rated for....and that voltage is NOT the same as the NOMINAL voltage of your battery pack. Put a multimeter on your charger and see what it puts out...that's the peak voltage of your battery pack, and that's what the caps and FETs have to handle. Most 48v controllers have 63v caps and 75v MOSFETs...the FETs can handle a 60v pack, but the capacitors can not, as the peak voltage is somewhere around 72v. Most 36v controllers will have the same components in them, but not all...you have to open up the controller and look up the specs on the mosfets, and you can read the specs right off the capacitors. A 24v will generally take a 36v battery, but the capacitors will only handle 50v, so a 48v pack (57 odd volts fully charged) will kill it. The internal voltage regulators on the lower voltage ones might not handle it and fry, even if the other main components can. I killed a watt-meter that was rated up to 60v by putting 61v to it. Oops. If you're not comfortable potentially blowing your controller or unsure, just buy a higher voltage controller to go with the higher voltage pack. Only an issue/expensive if you want the extra functions you get with a screen. Take aways... A little over-volting won't kill your motor. Bigger is better, for batteries and motors. There's a huge price-gap between low-power(street legal in most places) components and high-power ones; be ready to pay through the nose for the latter, unless you DIY it. Don't connect the battery directly to your brushless motor unless you're just looking for an excuse to replace it. "350w" on a folding ebike is quite enough to have fun while getting around. Don't eat yellow snow.

I changed a 36 volt battery in the nakto pony ebike to a 48 volt; the bike went from top speed of about 20 mph, to 32 mph. Big difference on my bike. Paul from Boston, Mass., USA.

just finished my ebike build, mid mounted 48v 1000 watt motor, did a test run just to make sure the breaks and everything worked i got in just a short run 45 km top speed with me using all the gears on the bike,,

WE DID IT AGAIN, LOOKED AT THE CONTROLLER AND TESTED ACCELERATION and also compared it with the 750w Engwe EP-2 Pro kzread.info/dash/bejne/eJia2ciEqcebn5s.html Don't forget if you love ebikes, escooters, electric unicycles and electric skateboards.... you should definitely hit that subscribe button for more content delivered straight to your phone 😉

So many aspects that would prevent the higher voltage from outperforming. The motor gears limit top speed in top gear. Your Controller limits the top speed of the throttle. Your controller limits the wattage or amperage. I do assume you are getting faster acceleration . That gives you the ability to take advantage of any slopes if you hit them at top speed vs a few miles below top speed due to the motor not reaching top speed yet.

The 48V battery installed in the 36V bike might not work to its full potential but it would interesting to compare two batteries, 36V and 48V same Amperage/hour, in a 36V bike and see the max range.

There are two factors, the controller and the motor. The controller will only allow so much current through based on the Moffats. If you know what you are doing you can mod them to draw more current. You were fortunate in having a dual voltage controller which you could switch in the settings, in most cases you would have to get a new controller. The other factor is the motor, where the higher voltage may result in more speed but it wont improve torque. So hill climbs wont improve by that much, but speeds on the flat, or going down hill should improve. So whilst you can increase the voltage to improve the speed of the motor, you would do better with a motor actually built for the higher voltages as they should also have improved torque.

@@nenobujas6567 Hi Neno I’ve seen a few reactions of yours on C20 Pro videos, allow me to ask you a question. I recently received my C20 Pro 500w but with a 16ah battery (which they describe as having more cells). They promised me it would be a 48v battery but it’s 36v according to the label. Motor is 36v also. It’s feels like a scam after their promise. What is your top speed and milage? Did you discover anything to improve it? Many thanks

Your motor will be rated to do so many revolutions per minute, for every volt you give it (This is known as KV Rating). So adding a higher voltage pack will increase the spin speed of your motor (more speed). In your case, your controller lacks the current (amps) to push it up to higher speeds. Hence you are getting 22+ mph down hill but lower speeds on flat or uphill sections. I shunt modded my controller so it had better up hill pulling power, I.E it provided more amps to the motor. Obviously there are other factors involved, like voltage sag that can effect top speed, for example if your battery is really cold or just has poor performance battery cells then the voltage will sag down when applying throttle, and you will get less spin speed as motors will spin slower the less volts you give it. Find someone who can work a soldering iron and get them to put solder about half way across the shunt, it will give a lot more zip, but try and keep the controller cool as it will generate more heat!

I think you are seeing an effect of not only the voltage, but also the amps that the battery pack can put out plus the overall increased capacity of the pack. Ah X V = Wh. Therefore, the one pack is capable of 374.4 Watt Hours, and the other is 614.4 Watt Hours. I would suspect that not only is the cells in the 36V pack lesser in quantity, it's possibly lower quality as well; and this is an area where most assemblers can make the MOST money, and that's in the battery pack itself. Many consider all battery packs as "equals", but reality is that batteries are an IMPORTANT consideration. While many might equivocate the amp hour rating of the battery pack as the equivalent of a fuel tank, it's far more than that. A 48 V pack is a 12 cells in series, with the amps coming from a number of cells in parallel as well, something like 12S5P ( 60 x 18650 batteries) ; and the 36V pack is 10 cells in series, again, with the amps coming from a number of cells in parallel as well, and I suspect a lesser number here - like 10S4P ( 48 x 18650 batteries ) . Generally speaking, while the voltage comes from the series connections, your overall amp output comes from the cells that are in parallel- and more cells of the same capacity - in parallel, tends to equate to more available power available from that particular pack. A 5P pack is going to output more current sustained easier than a 4P pack.. That definitely can affect performance.. Far more complicated than a tank of gas, eh ? Also far more important than most realize too. Some of the newer packs support newer batteries, where many older packs will use 18650's, some newer ones might be using, say , 21700's. 21700's work similarly- but the cell counts should be far less as less cells in parallel would be needed. One thing I didn't mention earlier, because it's sort of confusing, is that a 48V pack technically could have the same number of cells in it as a 36V pack by using lower capacity 18650's in the same pack, wired differently- a cheaper alternative. And if made in China, I sort of expect "INFLATED" numbers.. Another area where pack sizing comes into play is the lifetime of the pack. If I use 9 to 10 amp hours on a daily basis, for my daily ride, a 10.4 amp hour pack should work, right ? Yes, but- it will shorten the battery packs life considerably because I'm using by fully discharging it.. A 15 amp hour or 20 amp hour pack will have a happier, longer life .. Simply put, a larger battery pack works less hard, and will last longer. No, the manufacturers aren't going to advertise how they cut corners- they'll advertise price as budget minded individuals see, more than any other spec, price. Manufacturers will instead advertise an improved model with a better battery pack at a premium. Even if the motor or other components are the same, this is where manufacturers will "boast" about the capabilities of this model, etc.. Another aspect often not thought about is - for the same wattage output, a motor ran at 48V is simply going to draw less amps than the same setup at 36V. is it worth upgrading your pack ? If your pack is still good, not likely, but perhaps. Reality is, it should have been one of the things considered while purchasing. IF the pack is starting to fail, or has failed, and you were going to buy another pack - well, that's a no-brainer.. As others have suggested, it'd be wise to check out, with a temp gun, how warm the controllers and motors get during use- at both 36V and at 48V and see if the temperature is "safe" .. That said, you probably should also check how warm the battery is as well .. Like someone else mentioned in the comments, swapping batteries is sort of like swapping your old engine out for a better engine; reality is that any electric vehicle is comprised of many key components, like the wiring, the battery pack, the working voltage, the peak amps, sustained amps & the overall capacity of the battery, the motor itself and the controller. Limit ANY ONE of these, and you limit the rest of the subsystems.

I love the time you've spent to explain this to everyone. I have a 36/48 kit and I've had both batteries on there. The 48 reaches 26-27mph, the 36 22mph fully charged. acceleration is better with the 48, and so is range! Same amp hours. But more watt hours! By comparison, my 20s5p 72v samsung 40t home-built pack takes my 80amp bike around 40 miles on throttle only mixed riding, and 23 miles at full throttle full speed. Luckily my friend has a house 22 miles away and I rode wide open the whole way there, hung out for the day, charged the battery up, let people try it, and took it easy back home. I had gone down to 74v from 84 by taking it easy. Just wanted to share since you know quite a bit.

Range with the old 36v as well as the 48v version... I have the 36v tested on range in #2 peddling assist mode. Between 72-75 km distance, so that's pretty good.

Yeah i didn't plan on keeping the battery in for long. Would be interesting to find out what controller is in there. Some can take 2 different voltages but since the speed change was so small maybe this one doesn't take 48. Then again if an extra 250 watts usually gives around 5mph more maybe an extra 2mph going from 36 to 48 is about right.

Would a 48 volt 17.5ah work in the ADO A20 ??

The power is limited by the current draw from the battery through the controller, so I guess that is what is limiting it.

Hello, your opinion which bike looks more cool, more "muscle" and more fun to drive?

i have a question will it be unhealthy to run my bike motor from 48v to 26v I can change it in the settings on my ebike I do see a differents in power and time I can spend on 26v I just don't know if its worth it running on 26v

how much higher can you run the voltage? it seems you can adjust it on the bike computer, can it go to 72v?

Is the speed not legally capped at around 15mph in the U.K. and Europe. In the USA they allow up-to 25mph. As you can change the battery voltage settings on the bike yo7 shouldn’t have any problems.

Interested to know the range difference

I thought in the UK ebikes couldn't have throttle control. With a throttle the bike has to be registered etc as a motorcycle?

I have the ADO A16 which is 36v 350w and the battery life is shocking. They even supplied me with a second battery but I get the same result. On fairly flat landscape I can do about 14 miles if I pedal which is poor. Would 48volt help this significantly does anyone know? Cheers

If You want more range you need to add more AH, A 10 AH battery is roughly half a 20AH battery but you won't get double the range but you would get better range. Maybe at a guess 75 % more range, depending on how you use the extra storage capacity. You could put two batteries in parallel, I don't know how easy this would be on this bike as I don't have this bike.

So I have an escooter with 1000w motor, 36v battery. I wanted to upgrade to a 48v battery, got a 48v controller rated for a 1000w motor. but the motor is a 36v, 1000w motor. Will this work ? Or do I HAVE to get a 48v motor ?

how fast can you go using the motor and peddling in high gear?.

As I understand it, it depends on the capacitors in the controller. Many are rated at 63V permitting upgrade of the battery with no worries, as peak charge voltage might be 54.4 for LiMn or 58.2 for LiFPO4 or 58.8 for LiNCA types. (Terminal charge voltage, as represented on the label of the charger). Running 48V nominal packs should work with most controllers , with all 48V nominal chemistries. Your mileage may vary if those those capacitors are rated less. Otherwise change out the controller for a 48V nominal one.

If your in the UK 🇬🇧 how do you get around the 250W limit? Thanks :)

Higher Amps 50 Amp BMS @ 48volts would be fun ! What amp is the controller ?

Running a 36v motor with a 48v battery!!!! I think the motor will burn out. right? I have a 36v dc motor and a 42v scooter battery, can i use them together?

Assuming the 48v battery costs more than a comparable 36v the first consideration is the extra 2mph worth the additional cost , Secondary as you stated will the change affect the longer life term usage of the bike , some interesting questions which I suggest needs further investigation and another video .

surprised you didn't fry the controller.

I bought a 350 watt gear motor 6 months ago. I just bought a 500 watt gear motor and the 500 is half an inch radious bigger then the 350watt. Makes sense of needing larger gear wheels to have more power.

Feel free to ask. I only promised to tell you 'what happened' when I did it. That's what happened. Higher capacity batteries get more range though so yeah you'd get more range. But best stick with the same voltage as the original battery as you could burn out the motor.

I expect the controller config is the limiting factor. You would need to check the documentation to be sure.

I have the a20f also and changed to 48volt and although the controller does support 48 volt i suspect it should be going faster than an extra 2 mph, my suspicions are the controller would need to be upgraded as well to get more top speed, I have searched all over online to try and upgrade this controller but there doesnt seem to be any that are compatable with the ado a20f. If anyone knows of a better controller that would fit in the frame without any modification i would like to know.

Acceleration seemed faster with the 48v vs the 36 which is almost cooler than simply topping out at a slightly higher speeds.

More Voltage draws more Current through the circuit. More current means more Torque as it is proportional. Any acceleration you feel is the effect of Torque moving you forward by spinning the wheel. Top speed on the other hand is achieved when you are not accelerating any more and is related proportionally to max RPM achieved by the higher voltage input.

Try keeping the voltage on 36v while putting in 48v to see if there is an increase in power and speed.

I have a 36v Critter tricycle can you put a 52 v Battery on it?

There is more to it. Swapping controllers made a 500 watt bike into a 750 watt bike. And upping the current limit greatly increased the torque. For about $80, I'm much happier with the bike. It's the ancheer 26" 500 watt " mountain" bike. Now full class 2.

I assume you want to increase your range, so you need more amp hours on your battery but you have to look at your controller specs to see what it can handle. Increasing your battery voltage is going to make it faster and is gonna draw more power and might burn out your controller. You should consider buying a long range ebike they will have a bigger controller than your 36 volt system most have 40ah and even 60ah like Aniioki and Eahora. But there isnt really an ebike that will last you 6-8 hrs thats stretching it. The most youll get is about 4-5 hrs even if you dont want to pedal the whole time. Your 250 watt motor is not gonna cut it for you want more range. You should even consider a Wallke brand bike they have foldable bikes with big 48ah and even 60ah and is cheaper out of the other 2 brands.

Seen many people slip 48v into 36v. It's harder on the motor, whether it lessens the lifespan or not, I don't know. I do know if you run a bike that doesn't let you set the voltage you will have to find another way to read the battery because the charge display will not drop till the battery is dead because 48v batteries are considered dead at a higher voltage than 36v. So you might end up damaging your battery because the bike will drain everything it can from that 48

Will it burn the controller and motor ?

If the motor is rated for 36 volts and you go to 48 you would be fine. The eventual problems that could arise could be overheating when in continuous top speed use. Also make sure u change the settings in the menu. If you don't you could over drain the battery.

Would i be able to use a 24 volt motor with a 48 volt battery? Tia

I asked ADO if I can change the 36v battery to the 48v one you used and they said no it could eventually burn out the controller. So I guess the takeaway from this is it’s okay for a quick try but don’t leave it in the long term if you don’t want to burn out your controller in the ADO A20F. Oh and thanks for the test was great to see the results.

Usually you can tell if it's peak power or not, the advertising usually shows nominal, with bezior engwe and so forth, specifications usually show peak, but sometimes u can tell between 500w being peak and or more, most of the smaller cheaper ebikes are 36v with 16-20a controllers peak, if it's advertised as 500w 48v, usually peak power is 750ish dependant on the controller. This is very important to know cuz engwe has the L20 and they are 250w 48v, but cuz they factory limited to 250w and stamped with aprovavly and marked for 250watts they can sell it and u can legally ride it, so u can unlock it and get 500-750w(peak) and the cops if they ever stop u they check the sticker or imprint and it's in spec of 250w they are doing the same with some of their 750w ebikes now, so it's really important to check ebike voltages. 250-500w is a bit hard to tell peak Cuz usually they try stay hard in the law

This is allowed if your controller can handled high voltages but if not your motor wil overheat and controller which is which one is burn first

The battery output on the Engve is 614.4 Watts and the Ado battery output is 374.4 watts.

Headlight brighter?

If you change the controller too you would likely get a lot more power, the motors windings are optimised for 36v though so overheating might be an issue. Better to just buy a 48v setup if that's what you want, I can tell you 48v has much more power when done correctly, my bikes are all 48v apart from one 36v, 36v get me to about 17mph, 48v goes to 30 and a lot more acceleration too.

Ahr give you torque/acceleration V give you top speed, the reason the difference was small was because it was taking longer to accelerate, if the road was longer and level the difference would grow over time but both would eventually reach their top speed, I would expect to see around 5mph at least

It also has a mood where I can put it on the road mode, but I don’t know how to do it

Your onboard controller probably has a speed governor... so you will always remain in that speed range

You should be careful to only use batteries with a BMS, because a 36V controller will have a 28V voltage cutoff, but a 48V li-ion battery is already fully discharged at 36.4V so you could damage the battery without a BMS that cuts the power beforehand. Then there's the issue with the controllers over voltage cutoff and it's condensator voltage rating. My research told me that most 36V and 48V controllers have a condensator voltage rating of 60V, with a 48V battery peaking at 57V this works but not all 36V might have 60V Condensators, some might only be 52V rated.
