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.

You mean UPS backup for 500 watts? If yes, RENOGY INVERTER is the BEST AND RELIABLE ONE:https://www.amazon.com/Renogy-Inv...27R4J?th=1
I just got this but how do you wire it? Apparently this inverter doesn't charge the battery at all. How do you hookup the AC input? It didn't include any cord for that. Battery arrived on 25 percent.

Most inverter 1000 watt come with charger in one like brand "Eco-Worthy, DC House, Vevor, and etc" is NOT GOOD FOR UPS. Most people said UPS useless. And some of them price is over $200. The RENOGY is the best with UPS function most people reviews, but Renogy inverter does not come with charger. So you have to get a charger. Because it doesn't have charger function, so probably it don't give you a power cable for it. You got to buy a power cable for UPS function.

Below charger 20 Amps for 12V Lithium Battery sale $40 is the lowest I could find right now. 20 amp to charge 280 amp battery, it takes about 14 hours fully charged. If you want faster charging, it has to be more expensive.

Below is POWER CABLE. Did you get 1000 watt inverter right? If yes, this power cable is handle 1000 watt just fine. And this is lowest price that I find on Amazon for 6 feet long. It is cheaper for 3 feet, but it only $1 more for 6 feet.

After you purchased power cable, do like this picture to hook it: https://ibb.co/DfGn1StX
When you finish, it should look like this picture: https://ibb.co/JwzTY80V
Connect your electronic devices and use UPS function like this picture: https://ibb.co/GQYPgZMD

Any way to validate if these are actually Eco-Worthy Batteries and not a knock off/counterfeit? Thank you!

Finally received my third one and happy to see it on Overkill app. My other two batteries, only one is compatible to Overkill app. I guess the one not seen on Overkill is because it has a new BMS from another company.

Are you sure they mount as specified in the image for the AC plug? It shows them in the image wired to the bottom connections but the manual shows they are to be plugged into the top rectangle shaped ones vs the bottom round ones? I'm a little confused on that part and attempting it now. I have a 25ft outdoor 16g wire that i'll use for the ac plug.

YES, I'm 100% sure. Connect AC plug to AC INPUT (GREEN TERMINAL) like in the picture. I don't know what the manual said, but AC INPUT is terminal that your HOME ELECTRIC go into. Then it pass-thru your electric devices like computer, laptop, server, and etc. When you house electric is down, so AC INPUT doesn't have power. Your battery will kick in as UPS BACKUP like the picture I show up above comment.

Can you take a picture of your inverter and post it up here for me to double check? Because Renogy have 2 different 1000 watt inverter. So I want to make sure you have the correct one.

If you have 16 GAUGE WIRE, you could use that. 16 gauge wire could handle 13 AMPS. 13 amps x 120 volt = 1560 watts. So I work fine with your 1000 watt inverter. Make sure it has 3 wires (BLACK, GREEN, WHITE).

Below is my Renogy inverter 3000 watts PUH. I opened the BACK BLACK COVER to check make sure 2000 watt and 3000 watt is the same. Open the black cover and see your inverter have "AC INPUT in GREEN TERMINAL" like mine or the picture above comment.

My Renogy inverter 3000 watt PUH: https://ibb.co/TM9Q4cxK
AC TERMINAL HARDWIRE CONNECTION: https://ibb.co/GfGhx7Pm

Because you said you confused with manual wrote, so I downloaded the manual and check. The manual on PAGE 7 wrote exactly like I been told you to CONNECT THE AC PLUG TO AC INPUT TERMINAL.
Here is the manual wrote: https://ibb.co/0p1JxSfR

The picture below is also from the manual show you wiring direction. You see GRID POWER is wiring into AC INPUT? Grid Power is city power to your home breaker panel, then home breaker panel is spread thru many breakers into your wall outlets. So when you connect AC plug and plug into wall outlet your home. That is the same thing as picture. Then AC LOADS is where you plug computer, light, refrigerator, and etc into it. DO NOT DO ANYTHING TO AC OUTPUT GREEN TERMINAL. LEAVE THAT ALONE.
Here is the picture diagram from manual: https://ibb.co/RGs7Bv5x

Got my 2 in and they connect with OverKill solar so that's cool. They were both around 26% but when I charged the first one up I got an over voltage on one of the cells. 3.6v, lowest 3.37. after letting it sit over night they have balanced closer but I'm still concerned. Should I discharge and recharge them before I connect them in parallel?
