And now I'm considering using an auxiliary 12v lead acid battery to power the BMS controls.
When I first read this was an option I dismissed it as a car configuration, but when I saw it again recently I realized it actually eliminates all the headache of how hard it is to effectively fuse the small loads like contactors and relays off the giant 48v bank. I can run it all off basically a car battery and then no one can laugh at me for using automotive fuses! Ok well they can laugh but they can't correct me.
