There is some interesting and confusing post on this thread and while 12 volts is not REAL dangerous, the way this was going could (or maybe already has) created problems that didn't exist before.
It seem that I am adding to the confusion myself LOL.
I re-read that and I did type that up in a rather confusing manner...That's what I get for trying to make a quick reply from a smartphone while doing other things!! LOL
What I was trying to get at, or the point of the post rather, was to point out that paralleling two batteries of the same class will keep the voltage the same but double the AVAILABLE current (in theory anyway). This is oppossed to wiring the two batteries in series and doubling the voltage.
There are two reasons for ever wanting to do this..
1. Increased load on the battery bank so that adding a second battery would make the available current enough to cover the new load...or
2. To increase the available run time on a single bank charge while keeping the same load. (ie..Increase the overall AH rating).
My comment about the switch current rating would only be applicable to reason No. 1 stated above..
Sorry for the confusion!!
