Hi everyone,

I have 2 battery banks, one side has 2 large golf cart batteries that work great, the other bank has 4 six volt deep cycle batteries and a 12 volt car battery all wired together. Over the last year, Ive noticed that the 6 volt side wouldnt hold charge but still cranks the starter fine...lights are dim in the cabin but good starts using that bank...I figured the 12 volt starting battery is good but the 6volts are bad, they are even bloated like they gained weight or blew up.. so my question is, should I keep this setup and replace the 4 six volts with some similar deep cycle batteries or should I get 4optima sealed blue top deep cycle batteries and rewire... also these batteries are under the rear quarter berth... maybe a sealed battery is safer on fumes when charging.....forgot to mention, this last summer I replaced my charger, I have a Pro-Tech i-series 1240i 40A capacity...
