You can use batteries rated for higher than 35A, just don’t set it higher than 35A in the power settings of the custom firmware.

The extra wire from the controller goes between the two batteries on the series cable.

You can buy a series cable here.

Wiring diagram (Trace Cut)

Take note of the red line coming from the controller. This is the extra cable.

You need to solder it to your series cable on the wire between the batteries. There should only be one wire going between the two battery connectors.

If you have error 21 or you are using a smaller external battery like a 3S 12V and the controller won’t turn on. Switch the battery connectors.

For BMS data to work. It must be plugged in a certain way.

The controller is split into two halves. The top half controls the motor. The bottom half controls the electronics like the dashboard. Using the trace cut mod, the motor half of the controller is getting both of the batteries voltages added together. The bottom half only gets voltage from the extra wire that is coming from the controller. So if you use a 3S on the wrong side the scooter won’t turn on.
