Now, if you turn one motor, the other one will also turn (albeit with 50% less speed due to losses). What this tells us is an electric motor is the same thing as a generator. So in your cart, as long as you are slowing down in gear, not only will you have the braking effect of the motor, the motor will be producing electricity which should be flowing through and recharging your battery.

I'm with you on the motor is a gen concept, but I'm thinking the regen may be more complex. If have batteries at 70%, lets say 11.7v, on a 12v sys just to make things familiar. and I let off the throttle at 10% motor max rpm, say 5mph or something, ill only be generating 1.2v. This will not recharge the batts, on draw 11.7-1.2v x current from regen less power. There would need to be some way of boosting the voltage to say 14v to charge the batts. Clear as mud?
