Thanks man.i was able put my new batteries in my e300 someone gave me,thanks to ur vid. They thought it was broken,but I followed ur instructions and boom. Just needed new batteries.

Its good to see folks are keeping the e300s alive . keep on scooting yo

im upgrading the whole system with a modified vaccum motor and shunted speed controller like you did but the one part i needed help on was the fuzziest quality HAHAAHAHAH just my luck. But i did get a lot from the braking and kill switch identifying because that was one part that wouldve taken me ages to figure out on my own. Thanks again!!!

It was the capacitor blown by looks I’ve ordered one 35v 1000mf so my battery was 52v was that the limit ?

hi Kenneth my razor e300 controller has 3 red wires at the end is the first one batt + an next 2 power on/off switch .I cut them off to swap in a 36v controller but that not working so going back to standard.steve in uk

steve mcgowan Hi Steve. Make sure any different controllers have same outputs .Different controllers can have different throttle wiring. Usually throttle only needs 3 wires . Positive and negative and one for control voltage. Control voltage is usually a wire of lowest voltage ,and usually turn on a transistor or FET .You may have identify the wires from the actual throttle. Negative is easy.With Volt meter on continuity and One lead to chassis and other to a throttle wire till it rings .Other 2 will be power . You may have to juggle the two around to find the correct one if you don’t know .check voltage of throttle wires with battery connected with voltage meter.connectors can be spliced if they are different .and you have wiring diagram for new controller. A 36V controller will probably work with 24 volts but you will lose current. 24 volt motor will run on 36 volts but you may shorten motor life. Cheers

I'm on the throttle part with two orange wires and two brown wires and I'm trying to do the same conversion that you did the four slot to the six lot I wish I had a picture of the conversion you did any chance of seeing that

Hi . Not sure what you mean . Though remember the 2 yellow wires are negative, the red us power and green is signal which is liw voltage about 1.2 or 3 volts . If you have a multimeter with continuity you can find earth by connecting one end to metal ,say chassis of scooter must be bare metal . And one end to your wire . If it rings its negative, unless shorted but that's another story. Green wire turns on transistor inside controller and current flows . Some more modern throttles have an extra wire 8f using old controller box don't need. Later models will have an extra wire for the thus . It gives mire controlled acceleration due to being possibly connected to a digital potentiometer. Hope that helps . Have fun experimenting

How will i fix if the batterry not charging?maybe i have wrong wirings

Does the controller limit the top speed, I switched the 350W motor for my e300, but the speed is the same as the original e250W.

Hi The gear ratio has the greatest effect on speed. To increase speed you would need to change the gear sprocket but that's outside my field. Though you could compare it to say a 10 speed bike, where the bigger gears on the back wheel make it easier to pedal uphill but you change to the smaller gears to get faster on the flat surface with less pedalling. What you should get with the bigger motor is more torque from the motor which improves getting up those hills.

Hi Kenneth when u say chassis do u mean the controller chassis when testing for continuity ?

steve mcgowan Hi Steve. Any bare metal area will do for negative meter probe . Best using scooter chassis or negative wire.Yiu don’t need batteries connected to do continuity test.

Kenneth Jones thanks Kenneth for reply just had snow here in uk my cousin in oz.its an electric bike kit Ive bought off eBay now 36v 240 watt motor it span up ok when first connected its a front wheel hub kit then on test ride no power so asked for new controller but the same .the throttle lights up ok an when connected motor direct to battery 36v it tries to move .its 3 x 12v leads that ok it’s charged ok 36v so suspect motor sensors in wheel .im trying to use another throttle so will try find negative power an control 5v with meter on continuity .thanks

steve mcgowan Hi ,Controler should be connected power off for continuity test. Negative meter probe on any negative area. Bare metal on scooter is a good place or a negative wire. Same place for negative probe for voltage test to. Remember to put meter back to DC voltage setting and turn power on. If your trying to identify throttle control wires . Once you identify negative. The other wires will be have different voltages . The Lower voltage will be control voltage and higher voltage throttle Power itself.Use the throttle wires coming out of controller to do this. You now have to identify wires coming from the throttle itself and match them up with controller throttle wires.Black is usually negative. The positive wires can be any colour unfortunately.To identify the voltes you may have to connect original wiring and test throttle wire voltages . Control voltage wire is a very low voltage. Like 1.2 volts or even lower.

Kenneth Jones thanks the bike motor is trying to spin can hear buzzing when I twist throttle I’ve got my scooter controller an throttle connected but there’s 3 motor wires blu green an yellow so just swapping them

The the yellow and blue wire which one is positive which one is negative on the controller

Hi Yellow is negative on original controller, but best to check with multimeter .Any cheap meter with continuity setting will do it . Please read some of zhe other replys ,to find a detailed explanation on using the continuity setting. Hope this helps

I wish I watched this before I let the magic smoke out of my scooter 😩

my controller just clicks when I give throlller.batteries won't hold charge..old batteries for sure..I did by pass the control saw back wheel turning very slow..but only charged for hour..should buy controller and batteries??

Ozzie salvatico Should only need new batteries. Suspect some kind of controller problem if new batteries drain quick . You may have some internal short

How did you go with your mod and is the scooter still going 2 years later cheers Ocean

Ocean Tomkins Sorry I’ve been out for so long . Interesting you mention it . Laptop batteries not very successful. I did have the scooter going but it was under powered and the laptop cells became dangerously hot . I suspect I didn’t have enough batteries. It was hard to find many laptop cells and pulling laptop batteries apart and soldering them all up is like playing with a bomb. Not recommended really. There are cells designed for this purpose. They are a little larger than laptop cells and they are LIPO. They have slightly different voltage and chemistry.Laptop batteries where lithium ion I think . Look up headway brand . They are the ones you want. I can’t remember the model number of headway’s . 1820 or something like that .They can be up to 10 amp hour. They are expensive and there size is a little big for 8 of them to fit in a e300 razor easily. Not impossible though. 8 in series 24V. Wired through BMS(Battery management system)of course. Cheers

Who can print a electrical drawing, (schematic) off the Razor 250 & 300.????

I could probably do a block diagram . The controller is the only component that has any real circuit board in a razor 300 and as such schematics available from razor or from most manufactures are not freelt available e controller is most likely a couple of power transistors biased as switches to control the power Cheers

You would think that the, Razor.com, could have one on line.

still abit confused as to how you did the make shift throttle wiring but ill do some basic deduction and figure it out. EVERYTHING ELSE, SPOT FKN ON M8

hi Kenneth I just put a 18650 kit on my e300 its 5s6p x2 its 2600mah Samsung an Panasonic new cells it wasn't charged full just 3.60v per cell as they came but I'm charging now after test run with my hoverboard charger 42v lithium .it ran out of steam after a mile up hill ans stuff.i have a 36v controller an variable throttle on it

I didn't have brilliant results with the lithium cells either. Lead acid just last longer, possibly because they drain slower due to higher internal resistance.You really need 8in series and as many in parallel as possible to increase mAh capacity

question is if control is clicking .means its working. just buy batteries.
