ECO-WORTHY 280Ah LiFePO4 Battery 4-Pack: features, specs and who it suits

The ECO-WORTHY 280Ah LiFePO4 battery pack is a set of four lithium iron phosphate batteries sold together for storing electricity. ECO-WORTHY lists a combined 14.34kWh and aims it at RVs, boats, off-grid solar systems, home backup and UPS use. Here is what the numbers mean and what to confirm before planning a system around it.

What is in the pack

Each battery is a 12V, 280Ah unit. ECO-WORTHY gives the energy of one battery as 3,584Wh, and four of them add up to roughly 14.3kWh, which matches the 14.34kWh in the listing. Wired in series, four 12V batteries make a 48V bank, which is the voltage many larger solar inverters use. Wired in parallel, they stay at 12V with more capacity.

Why LiFePO4

Lithium iron phosphate is a lithium-ion chemistry that is generally known for a long cycle life and stable behaviour compared with other lithium types. ECO-WORTHY rates these batteries at 6,000+ deep cycles, which it says is three times longer than lead-acid. In general, a figure like that depends on depth of discharge and temperature, so treat it as a manufacturer figure rather than a promise for every setup.

Weight and mounting

Each battery weighs 62.8 lb (about 28.5 kg), which ECO-WORTHY says is a third of a lead-acid battery of the same capacity. The listed weight for the whole pack is 251.3 lb. The brand says the batteries can be mounted in many directions and have no leakage risk.

The built-in BMS

A battery management system (BMS) watches the cells and cuts power if something goes outside safe limits. ECO-WORTHY says each battery has a 200A BMS that protects against overcharge, over-discharge, charge and discharge over-current, short circuits and high-temperature discharge, and that it balances cell voltage. The 200A figure is a ceiling on current, so check that your inverter and cabling fit within it.

Charging times

ECO-WORTHY's examples for one 12V 280Ah battery are about 14 hours from a 20A LiFePO4 charger, about 6 hours from 600W of solar panels, and about 14 hours from a 20A DC generator. Real times depend on how empty the battery is and on sunshine, wiring and charger settings.

Expanding the bank

The brand says the batteries can be connected in parallel without a stated limit, and that 4 in series and 4 in parallel gives 57.3kWh. Always follow ECO-WORTHY's manual for how many units to connect and how to balance them.

Who it suits

It suits people building or upgrading an RV, boat or off-grid system who want a ready-made bank of matching batteries, and people adding backup power at home. It is not a plug-in power station. It needs a compatible inverter, charge controller and fusing.

What to check before you buy

• Voltage: confirm whether your inverter and charge controller expect 12V, 24V or 48V, and how you'd wire the four batteries.
• Space and weight: four batteries at 62.8 lb each need a sturdy, ventilated place to sit.
• Charging gear: check that your charger, solar controller or alternator setup supports LiFePO4 settings.
• Cold weather: lithium batteries often limit or stop charging in freezing temperatures. Check the manual.
• Fusing and cabling: use correctly rated cable, fuses and breakers, and follow local electrical codes and the manual. Use a qualified electrician for permanent installs.
• What's in the box: confirm whether cables and connectors are included.

The short version

• A four-pack of 12V 280Ah LiFePO4 batteries, listed at 14.34kWh in total.
• Series wiring gives 48V; parallel wiring adds capacity.
• Built-in 200A BMS and a stated life of 6,000+ deep cycles.
• About 62.8 lb per battery, for RV, marine, solar and backup use.
• Needs a compatible inverter, charger and protection; follow the manual and local codes.
