I am sure you addressed this but do you need that much power....in any critical sense ? CPAP machine for example ?

 

I have only one battery....and it is VERY heavy to haul around...cannot imagine two unless I used a lot of power on a regular basis or spent a lot of time static in one location.

 

Just my thoughts....will probably hear from others.

I am looking to add 150ah of 12v AGM batteries. It seems simpler and cheaper to buy one battery such as the vmaxtanks 155ah 12v battery rather than two 75ah batteries. With first time buyer discount its $350 delivered.
 
Any thoughts?

That much battery must weigh near 80 or 90 lbs.
Will it physically fit in your battery compartment & can you physically move it in & out of position without mangling your back?

Not like you'll have to manhandle it very often. More power. The more amp hours available lessens the likelihood you'll wind up drawing them below 50%. I was a little leery of the Vmax batteries, chinese batteries and not a lot documentation but so far everyone that runs them seems pretty happy with them.

No CPAP. Just want to have a bunch of capacity.

The question in my mind is one big one or two smaller ones? What makes the most sense assuming I can lift 90lbs and it fits...

Assuming it fits and I can lift it, one big one or two smaller ones, that is the question.

I went with two but I have plenty of space and the cummins doesn't care how much weight I have in the camper.

 

Two 125 ah batteries. Rain and cloudy all week. Finally this morning at 75% S.O.C I plugged the camper in.

I have the USA made (pre-Johnson ownership and move to Mexico) Optimas in my boat.

Mexico made Optimas in the camper. No issues going on 20 months. I'll keep my fingers crossed.

Agreed...no compelling reason to choose glass mat over flooded.

My experience was pretty dramatic when I upgraded from a flooded to an AGM

The AGM would take a charge from solar much much faster and would just generally behave much better.

Exact same wires, controller, etc.

Did a bunch of research and I ended up buying a LifeLine AGM. It was fantastic.

East Penn Intimidator AGM batteries have a good reputation in the marine world. ATC put one in my Bobcat.
