    Just got my (new to me) 2007 Sunseeker yesterday. It came with one old 12 volt RV/Marine deep cycle battery. There is room in the compartment for two batteries. Should I go with two deep cycle 12 volt batteries in parallel or two 6 volt golf cart batteries wired in series.

    I have a lot of questions, but will try to keep my posts small.

    Thanks

    Welcome to the forum James. I would go with the two 6 volt golf batteries but it really depends on how you will be using them. The 2 12s will probably be cheaper if thats an issue.

    I found this on the web and thought I would share it with you. :cool:

    "You can use one 12-volt 24 group deep cycle battery that provides 70 to 85 AH.

    You can use two 12-volt 24 group batteries wired in parallel that provides 140 to 170 AH. Parallel wiring increases amp hours but not voltage.

    If you have the room, you can do what a lot of RVers do and switch from the standard 12-volt batteries to two of the larger 6-volt golf cart batteries. These pairs of 6-volt batteries need to be wired in series to produce the required 12-volts and they will provide 180 to 220 AH. Series wiring increases voltage but not amp hours."

    Hope this helps.
    :)

    If you are a light user or boondock very little the 12 are cheaper. If you are a heavy user the 6 volt will do better. The interstate 2200's are good the T-105's 6 volts are better and you can go up from there if you think your use will be very heavy. For an example I have 4 t-105's and when boondocking don't really think about power. I run the TV when wanted and the micro, coffee pot and watch movies in the evening(during the day I run the 110 things off the batteriesfor shorter periods like making coffee or checking the news on TV)). Also run the furnace if needed at night or day but I run the Gen about an hour in the morning and 2 in the evening while I am on high use plus run the electic heaters if needed and heat the water with elctric. This keeps us in hot or near hot water. This keeps the batteries topped off all the time.

    Thanks for the answers. I'll probably go with the golf cart batteries, if they'll fit. We don't plan to boondock very often, but more power is better, I'm thinking.

    Again, thanks

    measure the space and then you will know what size you can get, just remember to wire them right

    RE: Battery Question

    Thanks to all. I have room (barely) for two 6 volt golf cart batteries. Walmart has them on sale for $70.00 a piece. I don't anticipate boondocking too much during the trip to Alaska, but once we get there, we will be out for a week or so at a time. The two 6 volts sounds like the better deal.

    Again, thanks.

    If you are going to be out a week or so you will need the 2 6volts. Do you have a generator? Even they probably want last a week if you have to run the heater.

    Re: Battery Question

    I agree with Nash, go with the 2 6 volts
    enjoy
