[C320-list] batteries

[RC - Compass Marine Services]

I would strongly urge anyone using 4D's to consider converting 6V GC2's or
group 31 batteries. Considerably lighter to move around. You'll have more
Ah capacity in a similar foot print and in 6V a much more robust battery
for deep cycling. Most of the 4D batteries made are a "dual purpose" not a
true deep cycle. Another option is to make both 4D's your house bank and
squeeze in an aux battery such as a group 24, 27 or 31. This will give you
more cycle life out of your 4D's.
