Looking at a lifeline GPL-4DA battery that has 210 amps hours. I have room to fit one. <BR> <BR>Currently I have 165 amps hours with 3 optimas and very rarely do I run out of power for the stereo. <BR> <BR>Cost is around $425. <BR> <BR>I am seriously leaning this way versus buying 3 of the Deka 24's or 2 of the Deka 31's. <BR> <BR>Is one big battery an ok solution for the stereo bank? I have heard these Lifeline's are top notch. <BR> <BR>(Message edited by murphy8166 on February 24, 2010)

Have you ever tried to move a 135lb object with simensions of 20x9x9? <BR> <BR>Just getting it in the boat is gonna take 2-3 people? <BR> <BR>It's not like lifting a barbell with 135lbs on it.

Not too worried about weight and awkard handling. Once it get it in the boat...it's not coming out. <BR> <BR>I am sure that I can entince a couple of buddies to help move this thing from the ground to the boat.

I see that as the biggest issue. <BR> <BR>Me personally, I'd rather move around and lift/pickup 120lb dumbells than move around a pair of 60lb golf car batteries. <BR> <BR>My batts are in my passenger side locker...and akward doesnt' even begin to describe it, lol. <BR> <BR>doing it twice has resulted in multiple cuts on my arms/hands and a very stiff back the next day. <BR> <BR>What boat?

It is going in an older malibu in the passenger compartemt. It is going to go exactly where the 3 optimas were.

Herniated my L5/S1 disk lifting both of my previous golf cart batteries up on the platform. On the positive side I was wakeboarding 6 weeks after the micro surgery for the repair.

at this point mike you're going to get a herniated disk lifting your twins =)

$425? I can almost buy 3 pairs of Interstates for that much.

I'm sure that you can. You could also fill you boat up with $425 worth of potatoes and draw energy from the them like a 3rd grade science experiment. <BR> <BR>Space &amp; battery maint...may be something to consider with 3 pairs or 6 total batteries in a boat.

Michael, you are comparing standard flooded dual purpose group 24 or group 27 batteries to an industrial grade absorbed glass mat battery that has the same capacity as 6 interstates and will be a much better deep cycle battery. It is like comparing a 17' bayliner with a 3.0 6 cylinder to a fully loaded xstar.

btw...Brett, I am going to go with a Deka 4d or 8d.

I have a pretty big system 3800 Watts rms. I ran it hard for 3.5 hours yesterday on just one of my 8D's and only lost 20% of the battery. If you have you have the space, as you say you do, get either the 4 or 8 and Lifeline is the best.
