Heres a brain challenge for you E-BikeKit experts. First off let me say I love my E-BikeKit conversions on my KMX tadpole trikes. My problem stems from the fact that I mounted two UPP 52 volt, 13.5 AH battery's on one of them for a little more get up and go. They are not connected in any way and my problem is that on one battery it runs fine but on the other battery the motor will not run at all. The LCD display lights up fine- just nothing to the motor. Battery voltage is 58.2 on the one it runs on and 59.8 on the one it doesn't. My guess is that the controller has a high voltage cut off which is why it won't power the motor. Any ideas on turning down my battery charger a volt or two so it stays below cut off range?
