v8.15.0
What's Changed 📦
Important info for Double Battery setups running automatic GPIO control! This version simplifies the handling of the secondary battery handling, requiring only 1 output to activate the POS+NEG contactor when the second battery joins. This will require wiring changes if you already wired this up. See #1232 for more info
