‘Not’ Another Battery Thread

[Tigger1]

This coming season we’re going to do a little dry camping, once the snow melts

We have an early 2018 Rockwood Mini Lite 2104s without front window and I plan to replace the single 12v Group 24 that came with it to 2 6v GC2s and want to put them into the same battery tray. I’ve already researched the batteries and boxes I want that will fit.

My question is for others who have done this will the battery tray hold 120-125 lbs. compared to the 46-48 lbs. currently in there?

If you have gone this route did you have to reinforce the tray or has it been okay?

I would reinforce the tray IMHO. Put a piece of aluminum in the tray and drill holes with nuts and bolts along the sides. Lite weight and ties the side rails together.

Thanks, that would be a simple modification.

Either way should work. Not heard of the batteries falling off but you'll feel better with reinforcement. I'd use steel angle iron and weld to the frame. Rattle can of black paint.

we had the 2015 version of that trailer and installed 2 Trojan t105s on the stock tray. We never had an Issue after 10,000 miles

Thanks everyone for your replies.

Tigger1 I have a 2016 2504s. I added treated plywood shims to the battery box rails then put a plastic box on top. After that I put 3 group 31 batteries in the box. Each battery weighs about 64 pounds each. Been 3+ years and no problems at all. Putting 2 6volts won’t be a problem IMHO. Jay.

Only reinforcement really need for the twin angle arm "rack" is adding a piece in the center to keep the angle brackets from spreading.

120-130 lbs is nothing for the battery supports.

I have 2 6v Trojan t125 in boxes and locking clamps and no issues. But I would check the welds from time to time as you live In a snowier area than I do

Mine came from the factory with 2 12v batteries (a pleasant surprise). They fit fine, and it looks like the tray hasn't been modified at all. I'm going to clean up the mess of wires that FR left at assembly and while doing that I'll take a closer look at the supports, but I think they'll be ok.

I know it's been beat to death, but I kind of like the idea of sticking with 12v batteries. If one craps out for some reason, I can keep the camper running on the remaining good one.

Either way, you'll have plenty of juice for a couple days of lights, fans and heat without thinking about it.

Thanks. I was at our local RV Show yesterday and saw both 2019 2509s and 2507s and they had two 12v batteries attached in the battery tray. I looked underneath and neither had any additional supports in the tray. I think I should be fine with two 6v’s.

Two 6 volts on Factory tray

Nice! and looks like you’re using the Noco 6v Snap-Top battery box which I plan to get.

Unless you have a way of monitoring the batteries independently, you will never know that one has failed until it drags down the 2nd to unusable. I had to learn this the hard way.

If using 2 Group 24 12V, 2 GC-2 6V will give you more capacity at a lesser price in the same footprint (just slightly taller). I switched to GC-2s after the failure of one 12V wiped out the 2nd in rather spectacular fashion.

just my experiences
