Well there are quite a few posts on the forum detailing settings for a 12S build, but here’s what I use.
The motor amps can control how powerful the board feels, feel free to turn them down if it knocks you off your feet every time.
Motor Max: 80A
Motor Min: -80A
Batt Max: 30A/2 = 15A (your battery is rated for this, it is low because of the two VESCS)
Batt Min: -12A (depends on battery, this is what I use)
For the absolute max and stuff, load the default settings first, and use those.
Someone else that knows the DIY battery feel free to comment - Also @Provoke try searching too, I got a lot of help from that when I was looking at this stuff, especially with settings.
