Hooking up (2) 12V batteries in
parallel will still give you 12V......nothing else changes except you will have more capacity.
Whatever you do....
DO NOT hook up your batteries like I have my (2) 6V batteries hooked up. I have them hooked up in
series, which doubles the voltage to 12V. If you do that, you will have 24V and may damage your converter.
The second issue is, it is not recommended to hook (2) 12V batteries in
parallel unless the batteries are matched. They are best if they are the same batteries, purchased at the same time and built in the same batch. Dissimilar batteries will have a hard time balancing and may cause issues. If you are going to use dissimilar batteries, it may be best to install them with a switch so that when one battery gets week, you can switch to the other battery.
