Can Two Batteries be Connected to Single Device on Trailer
Updated 06/24/2024 | Published 06/21/2024
Question:
Hello, Have a trailer with two 12Vdc batteries that will be powering the same device, but I also would like to be able to turn either one or both batteries on/off switch. It would be nice to charge both batteries from the tow vehicle, but also from an onboard AC charger. I believe that an isolator would be needed but am unclear on the wiring to perform what was described. Can someone help me out with this? Thank you, Greg

Hey Greg, as far as wiring the two batteries to the single device that would be just a matter of running switches from the batteries to the device as there's no reason you can't power a single device with two 12 volt batteries as long as they are wired in parallel.
Now to charge them yeah you'd need a isolator and the Redarc part # 331-SBI24D would work for that.
