I'd sure appreciate any advice on a modification to increase the number of batteries.
1. I found a cavity under the coach and am having a galvanized steel box with braces fabricated to hold up to 3 additional batteries. This will provide the ability to have up to 4 coach batteries in total, if wanted. The good news is that the new battery box will be only a couple inches away from the current existing house battery, so they can be connected together easily. The unfortunate part is that the 3 additional batteries will only be accessible by crawling under the RV and dropping the box down. I would use gel type due to minimize any maintenance issues. (this is the only compromise I can find).
2. 12 volt vs. 6 volt question. My first idea is to simply add (1) additional 12 volt battery for a total of 2 batteries.
- Would it be better to have (2) 12 volt batteries in parallel or (2) 6 volt batteries in series?
3. My other idea is to add (3) 12 volt batteries in parallel. Again, I will have the capacity to increase up to (4) total batteries once the fabrication is complete. This would actually allow (4) 6 volt batteries if that is a better option.
Any and all advice is greatly appreciated. I continue to find out how much I don't know
