So on my off road trailer build I'm trying to decide if I should go with 2 12v batteries or 2 6v batteries? What would you do? It will be running a water pump and various different LED lights and electronics. I also will have an onboard 2000kw generator that I can recharge the batteries with. Also wondering if you think it would be good to wire the batteries into my vehicles 7way brake plug so it can recharge while I drive. Not sure how to do it but I know it can be done. Is that a smart thing to do or just bring along a portable charger and recharge them off the generator.
