• Read up on and analyze previous revs of UV Cutoff

• Add a charging circuit?

  • Will also require active protection (over-voltage, over-temperature, and overcurrent, see section 8.3.B in ASC regs)

• Make UV cutoff compatible with aux battery?

  • Use the same PCB for both batteries, but some passives might need to change to adjust reference voltages, etc.

• Replace the high-side P-channel MOSFET reverse polarity protection with a low-side N-channel MOSFET for reverse polarity protection.?

  • N-channels have a lower on resistance, so it would be more efficient. It would also be safer on the low side. If the battery was connected backwards with a P-channel FET, then 12 V will be connected to gnd, which is a larger net so it's more likely to accidentally touch something conductive and cause a short circuit.

• The fuse could probably be replaced with an e-fuse to have a more precise current limit.
