Battery will be charged only if voltage generated by motor upon braking is higher the battery voltage (which is usually NOT) so for ESC to charge battery it suppose to have additional circuitry which boosts this voltage to higher levels (assuming we have only two wire going to battery!)

All hands for theory and understanding here!
do controllers have this additional circuitry?
If the voltage generated is lower than the battery voltage and we didn't have this circuit to boost the voltage then where would the energy generated go?
