Hi I need a Controller for bmc v4 hub motor (similar to mac)
Battery 52v 14s5p samsung 30q cells
Would like a pas sensor
And a throttle
Can.anyone explain or provide a link on how to select the right controller for motor battery, how many mosfets ect
Em3ev are out of stock unfortunately
Ideally I would like as small a unit as possible
The infieon controller I had was set to 30a
Seems to have stopped working tho wheels jerks slightly and that's it
