Are these batteries good?

I should get one of those plug in watt meters & check the fridge. It's a residential fridge running off the inverter. Sticker on the fridge says 350 watts I think, so that would be about a 30A draw at 12V when running.

That'll do it. My 12v fridge draws 2 amps at 12v tied directly to the batteries, so there's no loss going through the inverter to power it. It's a 11 cf. I would have installed a 17cf, but I'd have had to take one of the windows out to get it in and trying to lift it 8' and put it in sideways would have been a MF. 11cf does fine, but bigger would have been nicer.

I kinda think something happened to the converter I got the batteries to 13V & still no fan or voltage increase. Have to dig deeper I guess.

Blew to 40A fuses on the converter. Too much load from the batteries being dead I'm thinking? Works again.

Lifepo4 can charge faster and can take more amps, so I bet that's it.
