C99 firmware core for a 16-series LFP pack. Independent charge and discharge FETs, cell protection, coulomb SOC, and the current and voltage limits an inverter follows. Passive balance runs for 1.0 s, then 200 ms off, so the fault wait finishes on an unloaded sample. No RTOS, no heap. The AFE driver and fieldbus stay on your board.

We are a group of enthusiasts who want an interface to be able to talk to our cars remotely, perhaps add on-car displays (such as heads-up speed), and we want to have fun doing it.
