Hello William,
I did a conversion of a small pick-up truck and will probably convert my 27' sailboat. On the truck I used 24 6v U.S. Battery XC2200, which are 232 amp. The truck has been on the road since last fall and I've had no issues. When I am stressing them, like long time on the hwy. drawing 250+ amps, I do get a smell of battery. Otherwise I don't know they are there. The charger is a Quickcharge, 144v unit so it matches my battery bank. It also has been trouble free. I chose flooded batteries mainly due to tried and true reliability and cost, but for the boat the arguments for sealed AGM are compelling. I do have to add water to them, but not very often. Maybe I will go to AGM in the boat, since mounting multiple batteries in the boat may not lend itself to easy watering, which means it won't get done!

Hello all,
I am in the research stage of a complete dc / ac rewire of my 1978 33' hunter.
On the subject of House battery bank my thoughts are this
Plan A:
using 4 6volt batteries to wire up as 2 12volt banks.
Looking at either:
Deka 8AGC2 AGM, 6volt, 200AHr, C/100 220AHr, 68lbs, $225each
or
Trogen T-105 lead acid, 6volt, 225AHr, 62lbs, $140each
I think I would rather have AGM because of these being located under a berth, am I being too cautious on hydrogen gas and spillage? The Price difference is large but I think it may be worth not having to deal with venting and spillage concerns.
I plan to have 12V lights, navigation, radios, computers, lcd/tv, pressure water pump, black water pump, refrigerator, microwave, and maybe AC. (I know 12v AC sounds pie in the sky)
One of my issues is this, I have a DualPro 4 bank charger (4x15amp). As far as I can tell I can not use 1 charger bank for each battery because the charger is designed for 12V batteries. I think I can use 2 legs of the charger to charge 2 6V batteries that are wired up to be 12volts. Am I correct in this or would it be better to sell the DualPro and get 4 chargers designed for 6 volt batteries?
Plan B:
using 2 big 12volt batteries such as:
Deka 8D AGM 12volt, 245AHr, 158lbs, $400each
Then I could use my current DualPro set up with 2 legs going to each battery giving 30amps of charging to each 8D.
Plan B may be headache but I dread the thought of fighting to get two 160lb batteries in place inside the boat. Also, if I go with the 6volt plan I could expand my "tank" by replacing the smaller Deka 8AGC2 with these larger ones:
US AGM L16 6volt, 390AHr, 123lbs, $500each (same footprint just taller).
Which would almost double my available storage.
Any one with real world advice on any of this?
