Is it OK to have different sized battery banks. I have two banks. One with 2 batteries and one with one battery. All duel purpose wet cells. 3 batteries at 65 amp each. (195 amp hrs) I need to replace the two batteries . To get more amps I was going to use two 6 volts deep cycle. (230 amps) Plus the 65 amps on the single battery bank. 295 total. How does this effect charging?
