I swapped out the 2 cheap group 24 12v lead acids the dealer installed with 2 group 27 Duracell AGMís. No more water and battery acid and they can tolerate a deeper discharge more often.
Number of banks doesnít matter so long as it all ads up to 12v. In other words if they are all 12v then they are all in parallel. If 4 x 6v, then 2 banks of 2 each in series to make 12v each bank, then those 2 banks in parallel. If 6 x 6v then 3 banks of 2 each and then all 3 banks in parallel.
Just watch out for those cables; one of the positive battery lug terminals came off in my hand- never crimped right. Good way to start a fire never mind trouble shooting gremlins.
