I just completed a swap from NiMh to 18 Leaf modules (no BMS) in my 07 VX-1. I charged the pack to 146v, and took it for a test drive. The bike seemed like it was in limp mode, no power, 20mph top speed, with the motor controller squealing and bucking, with no regen braking. I used a light bulb to precharge the controller, so I don't believe that I caused any damage. Should I flash the controller and charger, to see if this fixes the problem, or do you suspect other issues? I have CANBUS cable a diag installed, and it works, just do not want to break anything.
