Why does the battery indicator show 84% for BBSHD motors?
Lots of customers used a 52V battery to connect with a 48V30A controller. Then the display might show high voltage error 07. So BAFANG has updated the 48V30A controller to 52V28A, then it can compatible with both 48V and 52V batteries. For a 52V battery, it will show 100% on the display when connecting to the 52V controller, but for a 48V battery, it will show 84%. We're still trying to resolve this matter, it's not a big question, it won't affect any functions.
