E-Bike System

[mistercrash]

I thought I would put this in here. I just ordered a Razor E200 scooter for my son for Christmas.



It runs on 24V (two 12V 7amp batteries) If I wanted to replace those SLAs with a couple of 6S 5000 mah lipos, what could I use for a Low Voltage Cutoff?

Or could I replace the controller

With a CC MMM and use that MMM's internal LVC? But what to do with the throttle twist grip?

The throttle is probably a typical 5k ohm pot. The MMM wants to see PWM pulses. Easiest way to do that would be to get a servo tester and replace the pot in the tester with the wires from the throttle. Might want to give some thought into how the ESC will react if the throttle goes bad though; I don't think you want your son to suddenly be running at WOT if something goes wrong...
