Evoride 36V 3-led

These batteries have a dumb BMS that we can replace, and they have only 40 cells: 10s4p. The BH flat spacers fit it perfectly.

It has 4 longggg M3 screws on both ends with PH2 heads. It is a bitch, because they are in narrow spots, so a PH2 screwdriver doesn't always fit. At least one oft hem needs to be done by hand with a PH1.

The BMS is on the charge end. To push it out, the off the two PH2 self-cutting screws from the discharge connector.

The typical problem with these batteries is that the cells go out of balance and then they need to be rebuilt.
