RXV is dependent on having minimum of 48 volts to the electric brake on the drive motor. check the voltage at the brake on the motor, has to be 48 volts.. Anything less, the brake will start to drag. Best to charge the batteries over night and then check. On RXV try to never let batteries get low!
I see question is still open. Did you get my response? Did brake release after charging overnight?
