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.

Anyone know if there are build quality differences (build versions) between these and the other ones?

There have been a few batteries that Will Prowse reviewed, but the one he reviewed wasn't the same as what someone else received. But it's hard to keep track of the different brands and models.

One major difference is that my old plastic version didn't have Bluetooth, so no way to know SOC unless you had the voltage chart to tell the approximate voltage left. 13.46 @100% to 12.85 @10%. Its such an awesome feature to see what the charge is on an app.

*Edit* - scratch that, this is a different 12v model, terminals on the side.
Still a decent price, but remember that these were going for 215 and 235 at different times in March.

Yeah, $215 or < makes sense to me, and this is not the eco-worthy store.

I recently used one of these to build a DIY UPS for my home rack. These things are HEAVY (66lbs) and seem to be of good quality.

I've thought about doing a writeup. Basically this + a Victron Multiplus are the meat. Then cables, fuse, and battery switch.

I have the old plastic version and it has been rock solid during an extended power outage paired with 1500w inverter. Kept my fridge going for nearly three days. Grabbing one of these. I like the side terminals for my setup.

I have this 280ah battery and am having issues with the Bluetooth. I'm currently working with customer support as a formality, but I know it's malfunctioning. Its tough having a relatively capacity battery and not knowing the state of charge.

I've always been a fan of Eco-Worthy batteries and bought them based on the consensus that they are good.

We will see.
