7) Why after turn on, LCD show "03_Info"
This is because of hall sensor abnormal, and most time is because hall sensor wires connection doesn't contact well, please kindly check the 5-wire hall sensor connector and also inside whether any pin bent doesn't contact well. If use quick release wire, please kindly check whether connector plugged very tight. If every connection is ok, then the most possible reason is hall sensor burned. (Very important: during installation, if need to remove the white hall sensor plug, please don't let hall sensor connector terminal touch phase connector terminal, otherwise hall sensor is very easy to be burned)

C4=4: PAS 0 level will turn off both PAS and Throttle, PAS 1-5 speed level is valid for both PAS and Throttle
9) How to activate Regenerative Function
Set C13=1 from LCD, save and restart LCD. During braking, battery will be charged back.
10) Which battery shall choose
You can choose 36V/48V Battery (full charged voltage shall be maximal 43.8/58.4V), Battery capacity best should be more than 15AH, battery and battery BMS board must support max continuous discharge current at 40A, otherwise battery will always cut off!
