ECO-WORTHY 12V 20Ah LiFePO4 Lithium Battery, 4000+ Deep Cycle Rechargeable Battery with BMS for Trolling Motor, Fish Finder, Ham Radio, Solar System, Outdoor Camping

Review: Good
Review: I recently picked up the ECO-WORTHY 12V 20Ah Lithium Battery for a variety of outdoor and recreational uses, and I am absolutely blown away by its performance and versatility! This little power pack is a true gem. First and foremost, the LiFePO4 chemistry is what sets this battery apart. It's incredibly light compared to traditional lead-acid batteries of similar capacity, making it a dream for portable applications. I've used it extensively for my fish finder on my kayak, and the difference in weight and consistent power delivery is remarkable. It powers the fish finder effortlessly for hours on end without any voltage drop. The promise of 3000+ deep cycles is a massive selling point. This battery is built to last, providing incredible longevity and value over time. Knowing I can cycle it thousands of times without significant degradation gives me immense peace of mind, especially for demanding applications like a trolling motor (for smaller ones, of course) or powering kids' scooters and Power Wheels for extended playtime. The integrated BMS (Battery Management System) is crucial. It provides protection against overcharging, over-discharging, over-current, and short circuits, ensuring both the battery's lifespan and my safety. This is a feature I specifically look for in lithium batteries. For outdoor camping, this 20Ah capacity is perfect for running LED lights, charging phones, or powering small electronics. It's incredibly efficient and holds a charge for ages when not in use. If you're looking for a compact, lightweight, long-lasting, and incredibly reliable 12V power source for your recreational gear, the ECO-WORTHY 20Ah LiFePO4 battery is an outstanding choice. It's a fantastic investment that delivers consistent, powerful performance. Highly, highly recommend!

*by R***. on 13 July 2025*

Update: 9/1/2025: I ran a test with the battery provided by Eco-Worthy. The battery was charged with a Victron battery charger until it was completed. Then the battery was attached to a 400 Watt ancient inverter driving a 60 watt incandescent bulb. The Initial power draw was 5.4A. 4 hours later, the total power consumption was 21.7 Ah when the inverter shut down due to low voltage of 10.8V. The battery is rated 20Ah, so it exceeded the specification. Previous Update: I am a retired electrical engineer residing in Florida. I needed a battery for a small solar project I am working on. The project is a set of attic fans made out of 20 computer fans that blow hot air out of my ridge vent. This is paired with a Victron charge solar charger. On the hottest of days, the fans can draw up to 10 amps. The speed varies as the temperature rises resulting in a max power of 125 watts. With this battery, that should provide 2 hours even without any contribution from solar. I powered this project with a single 100 watt solar panel, then added 2 more as I found the panels in general deliver much less power than rated for most of the day. With 3 panels, Mid-day, the solar panels provide enough power to charge the battery and run the panels at the same time. The purpose of the battery is to provide power before and after mid-day when the solar power drops off. It is most important in the afternoon as the attic is still hot after the sun sets. It works well at this point. Initially, with the first battery I ordered, the battery did not seem to hold much of a charge and the project would shut down way too early. The math just did not support that the battery was working correctly. I decided to return the battery. Eco worthy contacted me after reading my review and offered a refund, but I told them I had already received a refund form Amazon. They offered to send another battery anyway, so I agreed to re-test the new battery in the setup. When the battery arrived, I found it worked as expected. In short, I am pleased with the results, and as a potential customer you should know that the company has an active customer satisfaction program in place and stands behind their product. However, that being said, you should be sure to do the math and fully understand what this battery (20 AH) is capable of before purchasing.
