more importantly, you need a good charger.
Iota engineering make good smart chargers, I think the 4 stage, (4 being an equalization once a month) 55amp was under $250 and its a beast.
Iota does make good chargers but it is not a true equalization, more like a slight boost. The voltage doesn't rise to the 15.5 - 16 that equalization requires. Besides you wouldn't want to equalize the batteries monthly.
