Battery Location
Has anyone put their batteries in the electrical/plumbing area behind the wall in the pass through? seems like it would just fit and then it would free up that front compartment.
I am doing a solar install and already have a combiner box up on the roof with wires run down into that area. Lithium batteries and inverter are coming next week.Adam & Juli

I am doing a custom lithium battery
Bought calb cells and will be building a 900 Amp Hour 12V battery. also a victron 3000 watt inverter, mppt controller and some distribution fuses. I will be documenting it as soon as I get everything set.
It will be tight to get everything in there because of the plumbing being run as the crow flies but with a little patience I think I can manage it.
I took off the bathroom wall to run antennas for cell boosters and internet into the cabinet above the hutch, and at the same time ran dc power in there and also 2 pairs of 6 awg cable up to the roof for the panels. So all thats left is to put up the panels on the roof. And then the batteries.
Everything should be in next week so im getting close.Adam & Juli

These aren't lithium ion, but lithium iron phosphate (LiFePo). The way you build custom batteries is to buy individual 3.2V cells, and use them in groups to get to "12" volts. Then collect as many groups as you need to get the amp-hours you want.

Connecting 4 cells in series gives 12.8v with the same AH rating as a single cell. Connecting the 12.8v 4 cell series group in parallel to another 4 cell series group will keep voltage the same and double the AHs.

Oh ok, the CALB reference. Gotcha.
It’s actually better if he went with Battle Born since they do in depth testing on all cells they receive but only use the ones that test above X voltage. I’ve seen multiple failures on those cells people randomly buy from China. Plus the fact that each BB battery has a built in BMS. Pretty sure you’re not going to find a CALB supplier with a 10 year warranty either. You get what you pay for in this technology and this isn’t an area I’d recommend taking the budget route on.
