Overvolting Razor E300

[charlesv842]

The E300 has a 24 volt system, two 12v SLAs, and my question is whether I can overvolt with 6 more volts. Or even 12 more. Will it confuse the control module or not? Also, will it affect range?

If not much voltage i think it will burn the motors out

You need to know the cap voltage in the controller and the only way is to open it up and find out.

motor will heat up also faster so watch out. i burned one and then i modded one with holes in the case, worked a little better. at some point of higher voltage the mosfet will fry. this will be bad because in a brushed controller the failure mode is full throttle. my razor scooter at 60v....failed at half throttle and went to full throttle during a test ride. the scooter took off on its own leaving me running and flew across the parking lot like a slingshot hahahah

i would try 36v ....no more

mind you 36v could be 3x14.4v(float charge voltage of fully charged lead acid 6s cell so 42 volts......mabye try a 10s lipo??

so true about the brushed esc's failing and leaving you hanging at full throttle, lol. yup been there done that.

OP, yes you can. Over-volting to 36v from 24v is actually very noticeable. You would be pleasantly surprised.

But you must change the controller to 36v. Range will actually increase with higher voltage because you get to your desired speed right away and keeps amps and heat minimal.

might not be a bad idea to install some sort of kill switch or loop key on a tether so if you fall off or let go it cuts power?

that sounds frightening - full power on failure!

It's your skin - be careful (but take video! hehehe)

I ran mine on 12s lipo with no issues. Just charged to 4v per cell.
