About this item:
  • Metal Case for Enhanced Fire Safety
    • The Eco Worthy 280AH Lithium Battery features a heavy-duty metal enclosure for superior heat resistance and fire protection. It also includes a weak-current (low-voltage) power switch, allowing one-touch cut-off of battery output for safer installation and maintenance.
  • No Battery Box Required
    • Our 280AH Lifepo4 Battery features a rugged metal enclosure that provides strong protection and comes with 4 mounting feet, allowing direct installation inside your RV or camper without the need for an extra battery box. Saves space while keeping your setup secure and organized.
  • Shock & Vibration Resistant
    • The reinforced metal shell of the 12V 280AH Battery, combined with internal cell holders, keeps the battery stable during driving. It effectively resists impacts and road vibration, making it ideal for RVs, vans, and off-road use.
  • Bluetooth Monitoring & Low-Temperature Protection
    • Monitor battery status in real time via Bluetooth app—voltage, capacity, charge/discharge status at a glance. The Eco Worthy 280AH Lithium Battery features a built-in BMS that automatically cuts off charging in low temperatures to protect cells from cold damage.
  • Grade A Cells
    • The Eco Worthy 280AH Lithium Battery is built with premium Grade A LiFePO4 cells and a 200A BMS offering over-charge, over-discharge, over-current, short-circuit, and temperature protection. It includes a low-power on/off switch for safer installation, maintenance, and daily use.

According to the website, A-grade cells.

I've got an Ecoworthy from a few years ago still rocking really well. Use it to augment my power station when camping. If I had the payload capacity to spare, I'd buy 4 of these for 14kW of power in a 48v setup.

This seems like a better deal with a charger included. The listing says the two versions are the same. Does anyone know if there is any difference between these two listings?

I have had 3 of these, currently using 1 in my truck camper. They are legit. The app to monitor the battery is a plus. I am thinking about getting a 4th. Mine weren't the metal case, but they seem the same. $235 was the lowest price a year ago, but it bobs bewteen $334 and $250 + $20ish in garbage fees for a total $272 shipped.

You can. Need to be within range of battery. From main / 1st screen that comes up, click the 3 buttons at the top right, check mark the battery you want to change. click more options in bottom right, click rename. Wink

Heads up, Just got it for $217 shipped. I put this battery in my cart a few days ago and didn't buy . 2days later Cap1 sent me a $75 off $250 link. The price was $292 instead of $272, but cap1 link came up to save an extra $75. They do this for just about anything you put in your cart and don't buy(in a day or 2).

Got the previous version with plastic case & installed in our travel trailer. 280Ah is a BEAST - lasted 8 night camping trip with having to run the generator only once. Will add a 2nd one hopefully next year - much cheaper than doing a solar setup.

It depends what kind of loads you're running. This battery has approx 3.5 kWh of energy. I have an RV with approx 12 kWh of battery and I can easily kill it in about 6 hours by running the AC constantly.
