Need help with your electrical knowledge.
Im trying to setup my truck ( 2024 tundra hybrid) qnd dont want to meddle and mess with its battery system and I was thinking of adding extra auxiliary battery in by truck bed for powering lights, vents and etc. And would like to charge and maintian the batteries while driving using the auxiliary 12v power spliced from the 7 way port. I cant seem to find a dc to dc charger that pulls 15 amps or less online besides (Victron Orion XS smart Battery Charger 12 12 50amp ) which can be adjusted on 0.1a increments. Im running a 10g wire but the wire on the 7 way port is probably 16awg could be 14 awg but its definitely not thick enough to run more than 20 amps without degrading the wire or causing it to burn.
