72V DC controller
 

I upgraded my Yamaha Drive motor, controller and solenoid. After a bit, I bought a pair of Electric Lithium car batteries to replace the old ones. The nominal charge for those Lithium batteries is around 72 volts. My alltrax starts going wacky over 62 Volts, which is part of the over voltage protection.

I have seen one 72V that Alltrax makes but not sure if there is a regen model that supports yamahas.
