I bought 4 of them, over 3 transactions, on one account. I used the coupon codes that were on their main page. (USAS35, for $35 off $219, and so on)Total with taxes and fees for $921.02. (this number total is charged to credit card). I'm not sure how the -15$ off works through paypal, but I used it with my Citi 2% cash back card. I also had the urlhasbeenblocked-app open which has a 20% payback. That should be another $184 off my total. And another $18 off with my 2% card. At $921 I will have a 48v battery bank at 280ah. That's insane. Hopefully the other discounts work and I will get it all 4 for $720ish. Sorry for the jibberish... Hope this helps someone.

I have 3 of these on a bus to RV conversion that we mostly run in the winter. I was concerned about temps and being able to operate them in cold weather, and so far so good. We went as low as -30 F this winter and when the diesel gelled I was able to use a heat gun run off the batteries to warm the fuel system back up, get additives into the fuel system, and get everything running again.
We had to replace one shortly after receiving it that had a finicky Bluetooth module and didn't like to connect. The replacement was super fast and easy.
I plan to pull our remaining AGM batteries out, they're not worth the weight and space when these work so well.

Edit- I bought mine through their ebay site.

This ECO-WORTHY 12V 280Ah LiFePO4 battery stands out for its very low price, Bluetooth monitoring, and strong value for solar, RV, van, and backup power setups. The battery has been used successfully in cold weather, in parallel banks, and with inverter and UPS style systems, and the app support and fast shipping from Houston add appeal. Main cautions are checkout quirks, extra fees or taxes, and occasional Bluetooth or shipping issues, so the final total and unit condition deserve a close look. A solid budget battery for noncritical power projects.

Wow great price! I have the metal 150aH model and it's been great, no issues. Use it in the RV, lasts a really long time. App is easy to use for monitoring. I'd go for it if I had a need

I just got one. What's the best way to use this as backup power similar to UPS?
Spend your time doing research on what inverter/solar controller combo units fit your needs. Every installation is subjective! You don't want an inverter system that eats away a lot of battery while in standby mode if your application is for off-grid or off-season use etc. Some nice inverters consume 75w an HOUR regardless if it has sunshine or not. Thats a lot of pissed away power. Consider your wants vs needs and also scalability. Don't be afraid to dip your feet into the water and then completely install a new system if you decide to go full RT with clean solar energy! Even hands-on folks decide to walk away and go with a pro installed Powerwall with pro installed solar.

I want to treat this similar to UPS where I can charge or maintain charging at night (lower rate) and use it when there is a power outage. I'm looking for a an inverter and charger combo. Hopefully there's something out there that is affordable that I can use it with this battery set up.

If you want to use as backup when power go out of your house, there are 2 types of inverters. First type is 48V inverter/charger with split phase 240V, which could connect into your home electrical breaker panel. Second type, a smaller 12V inverter/charger, which cost cheaper but you have to run extension cord around the house.

How many battery you got? This battery is 12V only. If you got 1 battery 12V, so you need to 12V INVERTER. If you got 4 batteries 12V, you could connect them in SERIES CONNECTION to get 48V. Then you could able to use 48V INVERTER.

If you want to use MICROWAVE, you need inverter at least 1500 watts. So I need to know what kind of electronic devices you want to run.
