Good Evening Matt!
Thanks for the details.
Here's what I got from your discussion:
1. Buy a single 200AH battery and it will be good until it dies.
2. Buy two 100AH batteries and you will get about 150AH and they will be good until ONE of them dies. When the one dies, depending on how it dies, there is a chance that it has damaged its brother in parallel. So, instead of being able to depend on a backup battery, you may be in just as much trouble if not more so with 2 in parallel.
Some people have spoken about getting 2 6 volt batteries and using them in series for a 12 volt system. Is this situation pretty much the same as far as potential problems as 2 12v in parallel?
Thanks.
Steve.
