Hi, after the 52v battery install, did you change the setting for C12? Battery cutoff voltage, for 48v the setting is 4, did you change this to 5 or 6?Finally installed that 52V 17.5ah AliExpress battery onto the radrover. Holly hell does this thing fly now. The battery upgrade yielded a slight bump in torque and a faster top speed. It's easy to get up to 50 km an hour on flats cruising pedaling with PAS3/4.
@thatdude902 were you able to mount the battery using 3 mounting screws, I could only line it up and get the bottom two screws only. A little worried that this heavier battery is less secure on the frame, not sure what I can do to resolve this.
