This past weekend I installed the charger permanently into the car. The floor of my trunk isn't very level, so I used some extensions for the back bolts of the charger to get it mounted.
The charger requires a signal from a BMS to operate, but I don't have a BMS installed yet. As a workaround until then, I installed a 9V battery with a switch.
I'm still working on the controller cutting power when I throttle up. Once that's worked out though, I'll venture into the process of getting the car legal!
