Here is a link to thermal images and screenshots of a battery heater I put together for a 120Ah pack I built to go in a Pelican case. It took 1.5 hours to raise battery from 10.6°F to 42.6°F and then 40 minutes for the cell temperatures to equalize. A little over 7 Ah to get those results.

A friend bought a house with 720 watts of panels, 233AH 24 volt AGM battery bank, a 3000 watt inverter/charger/transfer switch. It also has a windmill on the roof (didn't climb up to look at specs. The windmill rotates to face the wind but the fan doesn't look like it turns. I have never seen...

I have a solar generator I am building/upgrading. I am putting a 2000 watt pure sine inverter, 40 amp MPPT charge controller, and one 4S 12volt 120Ah battery bank inside one pelican case. This will work well for my truck camper, 4H events and similar activities. I would like to make another...

Thank you. Is it possible to use these items as a solar charge controller at the same time? The negative from the 2 PV lines are attached to the bottom of the dump load.

Once I figure out where the cooling fans will be located, along with the new inverter, I should be fine. I’ll have to build some sort of structure to get around the ”wheel wells” anyway. I also need space for the heating pads to keep the battery warm in winter. This LiFePo bank will be going...

Thank you for the welcome. I had originally thought about two separate batteries. Harbor Freight has a case that 8 of these cells fit into nicely though. That's what got me thinking about building them 2p 4s (am I describing that right?). I guess I could also divide those cases to carry one...

My apologies. The redundancy I was referring to is still having good parts to put together a working bank, albeit at a lower capacity. So if I start with 3 banks of 4S, somehow 2 cells get damaged (run over, dropped, etc), I can still put together 2 banks fo 4S so a boon docking trip isn't...
