I have a 36v hub motor and controller (don't the current rating). I
used to have a 36v, 7AH SLA battery pack installed. It works fine until
I just upgrade my battery to a 36v, 15AH LiFePO4 battery pack.
Everytime when I push the throttle to the maximum, the motor runs about
5 seconds then stops. In order to make it run again, I have to turn the
power key off then on again.
I wonder is this because my controller is designed for 7AH battery
only, not the 15AH? Does this make sense?
