Hola, TL, DR, any voltage over 60v is too much.
This is information about the G-Drive Dual System motor controller ver 2.0, prod num ZN-A20 with a S830 LCD panel.
The motor controller states it is a 36-48v controller but in the programing mode it allows the following voltages to be accepted:
24, 36, 48, 60.
The original battery is assembled of 18650 cells in an 10s config with no BMS resulting in 41.8v at full charge.
I built a new battery out of 18650 cells in a 15s config and purchased a new charger, 63.4v@2amp.
When constructing the cells I used partially discharged cells so when the battery was completed the motor controller showed 45% battery.
It ran like the wind, under full throttle the battery showed 5% , I put it on charge overnight.
Next day battery shows 63.4v, I cool it and after 4 hours it reads 63.2
I put it on the bike, LCD showed 93% charge at 63.1v and the motor will not respond. I swapped the 36v back on and set the controller to the lower voltage and the bike rode again, boring and slow and I had to pedal up hills.
I put the 63v battery on a big 120v dc motor and fly wheel and ran it down to 62v, the LCD display shows 94% and still won't power the motor.
Sadly the only solution I came up with is a 14s and yet another charger.
