help please, I have just had my battery upgraded to lithium, with a second hand Heinzmann controller the motor spins but you can stop it with your hand - no power, I have found the 2 thin wires from the motor are not connected to the controller, could this be the problem ?
also found these words of wisdom, relating to changing to Lithium batteries
the Heinzmannn controller has a half voltage wire to monitor battery condition. You would have to disable this circuit.
any help would be great please, this is for my wheelchair trike which I hope to take to burning man festival in Nevada next Thursday !! ( I am paraplegic - cant walk )
