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.
Community Reviews
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.
Common Questions (6)
It is being used successfully in RVs, bus conversions, solar sheds, UPS-style backups, and house battery banks. Reports include solid cold-weather operation down to -30°F, long runtime, and years of trouble-free use on older units, but it is not intended for starting engines and should be fused because it lacks true over-current protection.
Yes. The checkout price can jump to $300+ unless the coupon is applied correctly, and some orders still show extra fees or taxes. A PayPal promo or seller coupon can bring it down, but the final total may still land around $206-$239 shipped depending on taxes and whether the promo applies.
Yes. The Bluetooth feature is useful for monitoring, but it can disappear on some units and may only come back after the battery is run down until the BMS trips. Other units have stayed compatible with the Overkill app, so the app support can vary by battery/BMS.
For UPS-like use, it needs an inverter with UPS/pass-through features and the correct AC input wiring; the AC plug goes to the AC INPUT green terminal, not AC OUTPUT. For charging, some setups use a separate 20A LiFePO4 charger, and a 280Ah battery can take about 14 hours to fully charge at 20A.
The coupon appears to apply to only one item at a time, so multiple batteries may require separate purchases or separate accounts. Some shoppers worked around this by splitting orders and stacking other discounts like PayPal promos or cashback.
That fit is uncertain from the comments, and one shopper specifically asked because the battery is large enough that two units may not fit where planned. If space is tight, measure the compartment before ordering rather than assuming a standard 2-battery RV box will work.

Cheapest I've ever seen them.
Look like Eco-Worthy just built warehouse in Houston, TX. Because I just received an email that my order is shipped. I checked the tracking, and it shipped from Houston. I just ordered this morning, and order will arrive tomorrow. 1 day shipping 😁
