Modifying 22' sunseeker or forester battery box?

Has anyone modified their battery box for 6v golf cart batteries?

I've measured my box under the step it is 7 1/4" W 10 1/4" H & 25 1/8" L. I think I can fit the CG-2 6v batteries in if I raise the lid / cover 1". The CG-2 is 7.11 W 11.07 H 10.3 L.

If not other ideas maybe another bank somewhere else?

Thanks

Hi Larry

Pretty simple process. I cut some 2x2 ( which is actually 1.5 sq ). And lined the bottom of the step cover. I used Gorilla Glue and then clamped it for the day. Trimmed excess off with a knife.

Re-drill the 2 screw holes ( through the wood). And then you will need to replace the screws with longer ones.

I think I also put down a thin strip of foam weatherstrip (1/8")



Install the 2 6V batteries upright and wire them accordingly. You can find that online. Just need to buy 1-2 battery leads.



The end result is the step cover is raised 1.5" and you won't even know it. The step cover has a 2" wrap on the front and perfectly hides the wood



Hope this helps. It was an easy mod and even though I'm not a Rocket Scientist the AH prove the results w better battery power


I going to do it. I have a progressive 60 amp converter, did you upgrade yours? We boon-dock so recharge by honda generator. How much power do you use before recharge? Wife likes to use the 90 watt TV.

A bit more involved, but I was thinking of cutting the bottom out of our battery box, then adding an inch or 1 1/2" with angle aluminum or thin angle iron to hold the bottom.

Doing it this way keeps the step at its original height and uses the original seal in the lid/step. The ground clearance is a bit less under the step, but it should be more than sufficient.

If I do undertake the project, I'll take pics and will post the process.

Battery

One question, how long does it take to recharge those 2 6 volts battery`s?
Compare to 2 12V type 27 battery`s.
If there all 50% flat.
Most Campsite will allowed 5 hrs Generator operation per day or less?

The battery box on the SS is the biggest complaint I have about moding my unit. I am having 500 Watts of solar put on this week but without changing dimensions of the box or moving the batteries I was left with two options (one might work for you).

1. Using AMG 6 Volts and mounting them on their side (box will fit two)
2. Using 3 group 31 12 Volts (rotating them from the original configuration) - What I opted to do as there are more AMP hours this way and cheaper than AMG 6 Volts

Will do in a few days as they are going in tomorrow.

The dimensions of my box are 25 X 15 X 10.5ish

The plan is to rotate the batteries clockwise 90 degrees.

Common group 31 size is 12.9" 6.75" 9.27" LxWxH

This means that 3 batteries rotated will give me a total dimension of:
20.25 X 12.9 X 9.27 ISH


Unlike 6 Volts you don't need to put 12 volts in pairs

This also gives an around 300 - 315 AH compared to 2 6Volts with 220 AH

So after some measuring we determined that you could fit 4 group 27s into that space for 400AH

Wow that's a big battery box. My 2016 Forester is half that size.

Didn't realize that all the boxes aren't a standard size. For those still struggling with solutions I would still recommend sizing 2 6volt AGM's and mounting them on their side (If your box is around 13" wide). If not you might consider moving the battery location.
