Request: No BMS Wire Diagram

Hi all, I have a spintend Ubox in working order with a quart battery but no working bms. I was wondering if a wiring diagram has been made for connecting the charger port to the battery/vesc without a bms?

there’s really no need for a diagram - connect all the reds and connect all the blacks and you’re done.

  • Battery red / positive goes to VESC red/pos and to charger red/pos.
  • Batter black / negative goes to VESC black and to charger black/negative.
