This 12V 280Ah LiFePO4 battery is being used as a compact power storage pack for RVs, campers, boats, trailers, and off grid solar setups. It stands out for deep usable capacity, lighter weight than lead acid, Bluetooth monitoring, and enough output for things like trolling motors, fridge backup, and even running an air conditioner for hours in larger banks. The main cautions are that it is not a car starter battery, charging and inverter setups need the right lithium compatible gear, and some buyers flagged seller trust and coupon issues. A strong fit for 12V storage projects that need real runtime.

Common Questions (9)

  • The final price has varied a lot because different coupons and PayPal discounts have worked at different times. Buyers reported totals around $240-$280 after stacking discounts, while others saw the code fail or the price rise to about $305-$330 when promos expired.

  • Yes. It is being used in RVs, campers, boats, trailers, and even for trolling motors, with reports of good real-world performance. It is a large battery, so fit and weight matter, and some users suggest a 100Ah unit may be enough for lighter canoe or occasional use.

  • Several buyers reported receiving their batteries quickly and intact, and some noted strong store ratings and positive order experiences. Others warned to be cautious because the store identity and refund process on AliExpress can be confusing, so buyer protection is important.

  • No. It is a deep-cycle power-storage battery, not a starter battery, and the 200A BMS is not meant for the several-hundred-amp cranking loads most vehicles need. It can run accessories, RV loads, audio systems, and other 12V equipment, but not engine starting.

  • It may, because 12.8V × 280Ah equals 3.584kWh, which is above the 3kWh threshold mentioned for the credit. The battery would need to be installed and used for home power storage by the deadline, and the credit details depend on your situation.

  • Use a proper solar charge controller for panels, and for power-station charging the input is often limited by the connector and voltage. A standard XT60 setup can be limited to about 8A/100W, while XT60i and higher-voltage series setups can allow much faster charging.

  • Runtime depends heavily on the AC's wattage and whether it is running full blast or just maintaining temperature. A standard 13,500 BTU unit running constantly may last under 3 hours, while a lighter 5A 120V load is roughly about 5 hours after inverter losses.

  • No. It usually needs lithium-compatible charging settings and may require a different charger, solar controller, or DC-to-DC charger, especially in RV or alternator-charged setups. It can work well, but it is not a simple swap from flooded lead-acid.

  • Yes, it includes Bluetooth, and the listed low-temperature protection stops charging below -7°C and resumes at 0°C. That makes it more suitable for cold-weather use than batteries without charge cutoff, though charging in extreme cold is still a concern for LiFePO4.

Be cautious of this seller, as it might be a fake. While the battery is great, this seller might be a scam.
I ordered two on Friday, just received the tracking yesterday and it started moving today. Ships via Fedex from NJ. Weight shows 65lbs which is in line with the other batteries I ordered from them.
I've ordered maybe a dozen things from Eco-Worthy, they all ship from random warehouses across the country.

Can I place 4 separate orders and use the coupon each time?

@gabe23111 or anyone else
Yes, I posted earlier that I did this but my post was deleted because I mentioned a certain cashback.

I got the ebay deal, and I saw this afterwards. It seems the ebay deal has already expired. The additional 4 that I bought just arrived yesterday, and now system is around 40Kwh. These eco-worthy has been great so far for 48V system. I also set up a series battery balancer, but I had to replace it recently. This is more cost effective than the server rack battery.

can i replace this battery with my current 12v on my chevy Silverado?
No. Your vehicle, especially a truck would take 600amps or more to crank. The 200amp BMS would cut the power off. This would be a good choice for an audio system, or for power storage for a RV or something like that.

Do you keep these in your garage or a separate shack just in case? I'm planning my solar system.

Good deal but these are not $1059 normally. Was looking at them a couple months ago on Amazon and they were around $440 each.

I keep mine in a shed, just because it is quite a messy. I don't really care about how it looks as long as it works, but my wife begs to differ. To me, a solar system is a long term investment, I'd get good solar panels (N-type TOPCON is great choice, and don't buy eco-worthy panels). I'd recommend Victron for electronics and get separate MPPT solar charger and inverter. With Victron, you can start small, and expand your system as you go. I don't think that you need expensive batteries, because battery technology changes pretty rapidly these days.

You can use any pwm or mppt solar charger straight to the battery. It all depends on your solar panels and your usage/needs. Your solar panels total Voc should be 20% below your MPPT voltage, and your solar panels total voc should be greater than your total battery voltage (for 12V, this should not be a problem).

If you are converting to A/C (alternating current), I'd recommend at least getting 2 batteries and wire them in series (24V DC) to reduce energy loss (48V is a good compromise).

I was planning to buy two and connect them in series and charge them with two 12v solar connected in series as well. I also want to connect to inverter when they charge is finished. What is a recommended charger that I can use to accomplish this?

No, it is not a simple drop-in conversion from FLA batteries. You may need a different charger/ converter, solar charge controller, and most likely some way to protect your campers alternator from burning out.
Thank you for the information.

How did you get 20% CB? I see 10% for new members (and 6% for me).

What are these used for in always seeing them posted
They have a longer duty cycle. (charge/discharge)
