6V vs 12V batteries - genuinely lost and my dog's comfort depends on me figuring this out.
Hey y'all, RV owner here, I've been going down a rabbit hole on house batteries and I keep running into this 6V vs 12V debate and honestly it's starting to make my head spin.
Here's my situation: I've got a 65-lb rescue Lab named Max who goes everywhere with me. My biggest worry on dry camping nights is keeping the fan going so he doesn't overheat, he's a panting machine even at 69°F. We're not doing anything crazy, mostly weekends at state parks, maybe some boondocking once I get more comfortable.
From what I've read, two 6V golf cart batteries wired in series are supposed to give you better capacity and longer life than a single 12V but I don't fully understand why, and I don't know if that's actually worth the extra cost and hassle for a rookie just starting out.
Has anyone here made this switch? Was it worth it? And if you camp with pets, would love to know how you're keeping them comfortable off-grid without blowing through your battery in 4 hours. Any advice is appreciated.
