Dave, I have a similar question, have read your various posts, but my understanding is more limited, so I'm not sure I'm following your advice properly.
I have two group 27 gel cell house batteries in parallel, and one group 24 wet cell maintenance free starting battery, all hooked up to a red charging switch that reads 1,2 or both. I also have shore power and a Link 10 inverter/charger.
My question is: am I causing damage to any of the batteries by charging them with the red switch on "both"--should I be charging the house batteries and the starting battery separately?
