I am looking at batteries that have the terminals at one end to reduce the length of wire to pass through the exterior wall to the tongue box - I am hoping the terminal to inerter distance will be 18 inches or less after crossing the bus bar, the fuse and the cutoff switch.

My RV only has a converter that I would replace with a standalone Lithium charger. I have to rewire everything anyway because I don't want the converter to run when the 120V inverter is being used. I will be adding an auto transfer switch and the Lithium battery charger will be isolated on the...

I didn't know the GC sizes were in the 230 Ah range - that means I only need two instead of three lead batteries. The weight is under 150 lbs and still stay under 80% DoD.

I'm hoping the car alternator can charge it up over 50% and use solar to bring the batteries to 100% during the day.

That is my plan too. Only the inverter will stay outside in the tongue box.

I have not seen anything close to that price here. I'm in Canada - all the prices I quoted are in $ CAD, it's about 1.40 CAD = 1,00 USD. I just checked again on Costco.ca : the cheapest deep cycle battery is 329.99 $ CAD = 235.71 $ USD. It's AGM though, I have not seen flooded cells for a while...

Your system seems to be working well but you are afraid of running out of power. I suggest you get a portable power station that can be charged with your solar panels. For about the same cost you will get something much more versatile.

Hello all, I am being confused by online videos that seem to all say that Lithium batteries are better than lead but are much more expensive... I am looking for at least 2 kWh of capacity to run a 12V cooler and a Propex furnace for a few days. Here is what I found locally: Cheapest flooded...
