36v jetson hoverboard battery

My kids hoverboards both depleted. Does anyone know how to jumper the bms so it will start charging?

You *may* not want to use those packs again if the cells have dipped below a safe voltage of roughly 2.5V. The first thing I would do is check each cell groups voltage. A 36V Lithium Ion pack is usually made up of 10 cells in series, so there will be 10 groups to check. I cannot tell from the photo, but there is usually a plug on the BMS board with all the balance wires from each group you can check.

I’m asking if any can read these circuits and tell me how to jumper or trick the charger into charging please. Asking for a friend lol
