ECO-WORTHY 12V 30Ah LiFePO4 Lithium Battery, 4000+ Deep Cycle Rechargeable Battery with BMS for Ham Radio, Fish Finder, Replacement of 12V 35AH SLA

Has worked well for us. Bought it to power a portable freezer/cooler when the vehicle wasn't running. We have also used it to power a pull behind sprayer unit. It has powered both items for several hours at a time without any issues. No problem charging. Holds a charge well when not used. I top off batteries every four months and it only takes a minute or two if it hasn't been used. A lot of power for so small a battery. Working for two years and going strong.

Very good battery, the material is premium and the charge is optimal! I had a question about which charger to use and the seller supported me in answering all my questions, the battery is quite good for its price and the delivery was on time

Works great!

It has only 28Ah instead of 30Ah. Seems like not much, but it is 7% less. I've tried with 3 different battery testers and monitors. Discharge show only 28AH, then charge show same 28AH. tried each devise 2 times, meaning ran 6 tests. All of them show 28Ah. Tried to contact the manufacturer. Left 3 messages. I's been 2 weeks already. No response. Update: Apparently the best way to contact them was via email on their website. They explained what i should do and took great care of me. Definitely recommend!!!

Have had this battery since May 2025 and it's June 2026 now and it's performed and charged flawlessly. No issues and would buy again. I wish the price would come down!

This is the second of these batteries I have purchased. They work great, and I have had no issues with the my first one. I like that they are lightweight and small, and are much easier to tote around for portable ham radio use than AGM batteries. However, it would have been nice if they had included terminal screws. Now I can't use the battery without a trip to the hardware store to fine some weird metric size ones. Minus one star for that.

Used once. Left in battery box for a few months indoors. Bricked now, won't charge. Update: replacement sent, excellent communication and customer service.

I bought this battery because I had the exact same problem with a different brand of battery. It charged up fine, but after I installed it in a brand new solar setup the BMS chip failed in two days. When I pulled it from the system and put it on the smart charger, the charger would not turn on. These batteries are shipped with unbalanced cells and the lower voltage cells pull the other cells down below the BMS chip's ability to recognize the battery voltage. I had a second ECO-WORTHY 20ah battery do the same thing, but I was able to recharge it. I bought a different cheaper brand and it did the same thing, except I was able to return it and got a refund. I bought 5 batteries to replace old failing AGM batteries and of the five batteries, three of them had defective BMS chips. Each battery failed in the daytime under full sunlight. All of a sudden the inverter started beeping and registered ZERO voltage. The charge controllers were brand new and functioning properly. So far I have not heard back from this seller concerning returns or refunds. I was able to return the other off brand and had excellent customer service. Right now I don't know the status of this issue, but I absolutely Do Not recommend taking a chance on ECO-WORTHY batteries.

Excelente batería. Excelente por su tamaño y su capacidad., la verdad es un súper precio. Más adelante haré una actualización de esta reseña en cuanto ya le haga pruebas de rendimiento con mi radio de radioaficionado. Estén atentos
