@Mike Gebhart wire your washer and 12v to the same batteries that way your washer is constantly charging the battery the 12v is on 🤝works every time and the 12v never loses juice during the day

@Mike Gebhart 6 gauge yes ! Also the bigger the wire for the 12v the better it will perform! They come with small wires that choke the power! Also recommend running two 12v batteries wired in (parallel) not series so you still get 12v but you just get higher amps some say it’s overkill but it’s just my personal preference that I’ve noticed a significant improvement in 12v performance
