If youíre happy with them, why not replace in-kind? Do you want something new?

Theyíre 6v, if Iím not mistaken. I suspect two 12v batts could fit where your four 6v live today. Usually that would lower your capacity, in similar footprint, but I havenít checked dimensions. It doesnít sound like you want to spend the money for the weight, capacity and charge advantages of lithium.

Keep in mind, if you change to anything other than flooded wet cell, youíll need to modify all your charging systems.
