Standard parallelization of batteries to my understanding is okay, but I'm questioning this unique circumstance since the batteries may have different charges (one may be fully charged at 13 volts and the other nearly dead at 11). Will this cause bad side effects or decrease preformance of either battery?
There is a switch commonly available to allow you to do this: Marine Dual Battery Switch
