I have 5 batteries on the house bank because the boat had an inverter/charger a couple years ago. They went from 3 to 5 batteries at this time. This past spring I had to replace all 5 batteries because one went bad and the charger "cooked" the 4 good ones trying to charge up a batterie that was not going to charge.

My question is why not purchase one or two larger batteries to do the same work but reduce the number of batteries so if one fails the others will not over charge and be ruined? Has anyone done this and if so what did they select to replace the large number of batteries on the house side?

Thanks
