I have four of these in parallel, 1000W of solar, paired with Victron components in my Western Range camp. I'm well pleased with the performance of these batteries. I've been using these for over a month straight with no issues thus far. it's the same price I paid for, but on Amazon several months ago.

I have a furion chill cube 18,000 BTU soft start AC, microwave/air fryer/convection oven combo (I try to use the gas stove/oven where I can to avoid microwave combo), three-way refrigerator/freezer, water pump, tankless water heater, laptop and docking station, 65-in LG OLED G4, sound bar and subwoofer, PlayStation 5 pro, small fans, star link as well as T-Mobile routers, lights throughout the camp, and several phones. Helping me with this is two 40 lb propane tanks. I also have a tri fuel generator that sits on the deck of the camp for redundancy or as needed. Propane is primarily used for the tankless water heater and the gas stove / oven and furnace, but it can power the entire camp as well with a push of a button on a fob. Propane is also used for a gas light within the camp. while not relevant this bad boy also has a wood stove. I'm running a fairly full load 4-5 hours a day. fortunately I am at around 7, 800 feet up so it is cool enough to keep the windows open and just run the AC occasionally. Most of my day is out hiking or fishing.

I didn't know we could stack these. I bought a $50 rack of temu to put 8 on.

I've been using 4 165 DC House made by the same company as eco worthy for the past 9 months. to run my house. I cut the grid power 6 months ago and so far my house has never turned off. I bought 4 of these and will hook them up tomorrow.

Maybe a dumb question, but is this in an RV, cabin, ...? I need an AC for my trailer and that furion looks like it might work.

Can I use this Charger/Inverter: https://www.ebay.com/itm/126974222925 to charge/invert 2 of these batteries? With my crazy California Time of Use rates, it would appear I can peak-shave and payoff within 2.8 years for a 320w server load (after tax credit). Seems like that charger/inverter will work if I put the AC input on a switch that shuts off when peak rates start and turns on when peak rates end? Then I'm sure there's some other way to use Home Assistant to monitor the battery charge/health?

I tried this one and ended up returning it as it could not run a ~950W load for more than a second.
As long as your 320w load never has any spikes (e.g. during startup) >900w, it's probably fine.

Quote from CharlesC8433 :
Anyone know if this size would be sufficient to power a medium sized car audio system? A four channel with a mono block subwoofer amp? This would be a dedicated battery for the stereo only and would not interact with the car's electrical system. I do have a Keyline dual battery isolation kit so it would charge only while the car was running.
Should be able to pull about 2500w max if needing more could parallel and connect to a buss bar. Just dont charge during sub freezing temps to avoid lithium plating issues.

Depends on what you're trying to power. This is what we use ours for and we have a 3200sq ft home with nothing fancy. we never try to run high draw appliances like the AC or Dryer, but it runs our fridge(s) lights, TV's, internet, etc. We bought a charger from Amazon and have a few pure sine wave inverters. Pretty simple setup! Highly recommend them plus they qualify for the 30% federal credit!!

Is this good for an electric engine for a boat? I go for a fishing trip once a year for five days in Northern Quebec where the last cell signal is about two hours away. Do you think this would last 4 days of fishing for 6 hours a day before needing to be charged?

This seems like a new low price record. Under $90 per kwhr... with bluetooth BMS. Nice. I'd prefer 48V batteries, though. 12V requires a lot of current and I'm all in on 48V systems now.
