This is all really good to know, been working on the a concept for a modular based enclosed e-bike/trike. An the fact of getting closer to where i would have to look into the batter/ies that would power the system/motor/s of the bike is getting closer so looming in mind abit. Even looking at how big the battery should be for the bike/trike to power the number of hub motors on it effectively the best, while keeping it removeable so it can be brought in during the winter seasons.

Very useful. I think the danger of cheap batteries is that they will fail quickly and/or not deliver the promised voltage and/or AHs. Great video, thank-you.

Such a great question to answer. Thanks Johnny!

I have two battery packs. One is the Luna pack 13.5 ah using LG cells and it gets about 1150 watts max fully charged . The other pack I have which a 6ah purchased from yours truly JNO , has samsung cells and it gets close to the 1300 w max on my bbs02 , I see 1250 or so when fully charged going up the same steep hill behind my house. Samsung 30q cells push by bbs02 to 1250 watts or so while the LG MJ1 cells push it to around 1130-1150 or so range.

Nice video. I appreciate your efforts to share your knowledge

This past week when doing research on hydraulic disc brakes for electric brakes, I came across a seller that recommended against me using the same brakes included on super expensive premade brakes on any ebike. Also when asking if the brake levers were left or right, they didn't answer until I asked three times. I got my BBS02 from you. You clearly know more than the seller of my front hub motor. I had to try si many different tools before figuring out that T20 Security is the right tool for the hub motor disc brakes. Amazon sellers don't always know everything and you are definitely at risk of getting something that doesn't work. I got refunded for a bike that came with a bent front fork and the seat post also got stuck inside the frame. Big frame scratches too.

better brakes are always the choice for e bikes My little carbon folder tops out at about 35mph/50kph. This is with little 20inch skinny tires the last thing you want is bad brakes at 30+ mph If you have the opportunity go with good disc brakes everytime . I live in a very hilly area , at most times I'm full stop on both brake levers going down steep inclines. They work very well

Love your videos. I have converted two bikes so far here in Portugal, I converted one downhill bomber for my wife so that it would be unbreakable, and my crappy hardtail for myself and your recommendation to go mid-drive was 100% correct. Way better! I have a question I hope you may know and have the time to answer...are all these down-tube battery mounts the same so you can mix and match mfrs?

Years ago there was a lot of truth to this. No longer. I am not talking battery capacity or weight. There are minor differences there. I have yet to disassemble a generic battery that did not have Samsung or Panasonic cells anyway. Because they have to mass produce these now, mfg processes are more and more standardized. There is not a significant difference in quality of assembly from a mfg. The odds of a battery fire, from a factory battery that is not attached wrong, damaged or charged with the wrong charger, is a whole lot lower than the odds of being killed on your bike. Nearly all reported e-bike fires are actually e-mopeds. An amazing percentage are being over charged in homemade charging stations. Other than them, home made (hand made) batteries, aftermarket "rapid chargers," cracked cases and questionable connections, account for nearly all battery fires.

Thanks. Really valuable information.

After a lot of scientific research into batteries I broke it all down into "invest the extra in not setting your crotch or butt on fire" (depending on where you mount your battery).

I have used Johnny for consulting ang he is real great.

The mantra of ‘avoid burning your house down’ is not just rhetoric. As an investigator, I have been to houses that have burnt to the ground as a result of cheap lithium batteries. One unfortunate bloke had just received some generic batteries in the mail and left them to charge while he ducked out. He returned home several hours later to find his family house ablaze. We later identified the charging point as the point of origin for the fire. Saving a few dollars for cheap battery packs is not worth the risk.

I will confirm that there is a substantial cost difference between cells. It fluctuates frequently too

Mine 58.8 volt $999 i bought 2 ! With the best cells ! From shop and talked to person that puts them together took me 6 places ! Finaly got a good guy here in NSW Australia ,also got a 56.4 battery 48 volt to ! Buy the best not worth buying cheap !

It's also a logistics issue. Small low volume sellers simply won't have the ability to buy like the brands selling 10's of thousands of products. If I buy a motor kit locally I might have to pay twice as much to buying through a Chinese seller who maybe ships from the UK or Europe. I doubt if the factory door price of those decent cells are $7 that is probably the price for small volume buyers, it could be high volume buyers pay only $4 maybe less. I mean walmart sold a very basic ebike I think for $399 if I remember rightly. You break down all the components plus shipping, tariffs, profit etc you probably have no more than $50 for the included battery. Samsung do a very safe abuse-able cell that is not particularly energy dense which features in a lot of battery packs as its a recognised brand. The battery pack will end up a bit heavier than battery packs with better more advanced cells but still a good option. Any complete ebike sold in the UK, Europe and US through normal retail channels (not personal imports) has to go through the certification process and the cells will have to be fully certified i.e. properly tested to be legally sold even those super cheap walmart ebikes. However on aliexpress sellers have filled cells with sand (not kidding) on some battery packs and powerbanks. It's like only half the cells are real cells and the rest is just padding. That's why its important to take your time if buying on aliexpress and go with the sellers with very positive reviews and a high number of sales if you are trying to save money. Also I think some of the Chinese cells are ok, they aren't all bad but many are unfortunately. Some of the complete ebikes sold at retail across Europe, US etc do have Chinese cells. I bought a couple of battery packs from ebay before the pandemic. Ebay had a 15% off code at the time and the seller offered a generous discount if you buy two battery packs. They have the basic Samsung cells in a Hailong case. I think I paid £150 each approx possibly slightly less and they were 48V 12.5Ah. I think now I'd be lucky to pay less than £230 each.

You get what you pay for!! Great advice!!

Great vid, but one thing was left out, battery chemistry. LiFePO4 cells are far cheaper than standard lithium ion (or at least they have been, who knows what the future prices will be). I bought my 0.5 kWh LFP pack for just $200. Seemed too low, but with LFP there’s next to no worry about fire so I went for it. It was very bare bones though, with just shrink wrap and wires I had to solder connectors onto. I would have gladly paid more for a fully packaged LFP pack, but I couldn’t find one anywhere in the US. If you could offer them in your shop you’d fill a very specific niche.

I've noticed you can very easily get packs from Ali that come without a case, they seem to be half the price or less than a 'good' battery like a UPP ( loius rossmans exploded though ).

That's why you can't find a seller who claim using Samsung or LG cell. I am also a ebike battery manufacturer, you are welcome to ask me some quesiton about battery.

I am trying to ride 400 miles in two days. I can't afford for the battery to die with a 60lb bike

Those cheap battery cells typically resells for $1-$1.5 each in China

Do you know any good ebike supplier in Europe?

Buy a kit then build one.

Made a review of aliexpress battery casses on my Channel. Also those with the Bluetooth BMS are much better.

how about you buy premium and end up getting low quality at premium price?

So who are the reputable manufacturers of E-bike batteries? Who do you trust is putting in the cells they actually spec'd out?

So batteries aren't meant to start fire or over heat? Crazy 🤪

I was going to convert my Trek Remedy 8 Full Suspension MTB but. Battery will not fit in the triangle, Rear racks have drawbacks and a battery in a back pack seems like a hassle? Any suggestions on rear racks or?

What’s wrong with buying good lithium cells and assemble them yourself?

Anyone having experience of bestebikes batteries, they have 4 certificates and I think they are real,530 or was it 600 bucks for 52v 17.5Ah battery with LG 18650/ Samsung 21700 cells, they have had no problems with the batteries atleast when I looked at the reviews. and I can't find any good/reliable seller/builder for ebike batteries here in Finland so just asking for a advice, do u think it's worth to buy battery from them.

Must admit I've bought quite expensive e bike batteries from amazon, claiming quality samsung cells, but unless I take it apart I won't know for sure! ..so it's a bit of a lottery really, time will tell I guess.

The battery pack should cost $450 for a $595 ebike!?

definitely be weary of a $595 ebike….they cut corners on many things to get that price

I have to add für the people, which are reading this, that it’s not completely correct. Yes, there is a difference between cheap Chinese cells and good quality cells, and I would advise everyone always to use the good known one (Samsung, LG, Panasonic…) but you can’t just say that they need to cost 4$ and more. I use the Samsung 50E cells and buy them for 3,50€ from an official store. Bigger manufacturer will always get good Rabatte when they take some thousands of cells. A simple maths shows, that for example car maker pay under 1$ for a cell and they surely don’t use the Chinese one. The next thing is, that I agree, that a not properly build battery pack is very dangerous but it surely doesn’t cost 200$. When you know how to handle high voltage and high current it’s actually really easy to build the battery pack and unless you are not a big brand like Bosch, you will use every time the same Chinese housing and Chinese BMS and so on. In the end there is no need for paying 200 ore 300$ more. This will not guarantee you any quality. It’s better to see if the seller lists which cells are being used and what’s the reputation or feedback of the seller.

We are getting absolutely robbed for these batteries, tesla says their batteries are $120/kwh, fords lfp batteries are down to $80/kwh yet ebike batteries can easly cost over $1000/kwh. Same thing for power tools...

Its scale. If you only buy 80 cells for an ebike battery it’s much more per unit than when ford buys 800.

@@JohnnyNerdOut we already have "scale", so your telling me the companies selling ebike batteries don't buy em in bulk? All the cordless powertool and yard work companies not buying em in bulk? No scale there? Even if I order the minimum of 5000 cells to get the cheapest price, it's still a complete ripoff. When I built my first ebike almost 10 years ago they said the batteries are only going to get cheaper blah blah blah, yet I'm shopping around for a new pack and they cost more then they did 10 years ago!

You get wha you pay for!!!

*YEAH YOU CAN BUY HIGH QUALITY BRAND NAME BATTERY. BUT THEY CAN STILL CHEAT AND CLONE THAT EXPENSIVE HIGH QUALITY BRAND NAME BATTERY AND CHARGE YOU HIGH PRICE.*

Just like anything else in life.....quality! Do you really think McDonalds is the same as SmashBurger? Nooooooo!!!! If someone said they had a 2020 Ferrari for sale at $15k. There's something WRONG with it

$200 just for the labor ?, that's more than my battery, add a little bit more it's my whole e bike.

You get what you pay for!!!
