72V 120A Kelly Controller (Only Controller)



Due to adaptation issues, models equipped with this controller may have the following problems:
(1).Currently the fastest test speed is about 68mph.
(2).No brake lights.

(3).Need to adapt to the high rate of the battery, like we match the Samsung battery cell.
