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!

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.

I received this battery about 3 months ago. I've been using it off and on to power my amateur radio. Last night I started a test to see how well it will hold up under consistent use using FT8. I set my radio to 25 watts and have left it on continuously. When home and awake, I've been running FT8. Just now, the radio shut down and reset on transmit. The battery is 12.14-12.16v and has used 19.6AH/247.2wh. The radio shuts off at 10.5v. I just turned the transmit back on in WSJT-x and it transmitted three rounds of CQ without quite hitting the mark to turn off the radio. The battery voltage dropped to 11.75 volts, but has since gone back up to 12v while the radio is in receive. The radio is using .72A on receive at this voltage. (@ 13.8v, it draws .66A.) The battery built itself back up a little bit and was able to continue after the radio shut down. For those who do not know about FT-8, it is a digital mode that heavily works a radio. It transmits 15 seconds on and 15 seconds off as long as one is there keeping it going. I hooked the battery to my CB and let it scan, no transmitting, and the voltage is back up to 12.5v with the radio pulling .2A. (I'm killing the battery to fully charge it to balance the cells.) The battery is living up to its stated rating of 20Ah even under moderate, steady use.

These batteries are a great value. I was concerned to buy a battery from a company that is not a household name but these batteries curbed that concern. This was my first ecoworthy battery that I've purchased for myself but I have bought a few for a non-profit with great success there. The battery feels well built, included the terminal screws needed, and seems to last the advertised capacity. There is no voltage drop when keying a 50-watt FM ham radio. Overall, I am really happy with these batteries and would not hesitate to buy another. These make great batteries for ham radio kits, POTA operation, and emergency battery backups.

Use for ham radio field and POTA. It consistently drops below 12volts at 16-17AH. Manufacture did refund me $10 as after many e-mail exchanges and many test, they said it was within specs. Have different brand 12AH battery that is at 12.2v after 13ah. I do also have their 50ah battery and it is doing as advertised. Update: Manufacturer sent me a replacement 20Ah battery. So far after two cycles it is performing much closer to what I expect. For QRP work it is definitely the battery to use all day. For my 100Watt radio it still doesn’t quite get the 20 Ah but may improve after several more charge cycles. This battery is still a good one for the money.

I bought the 20ah Eco-Worthy battery to replace a SLA battery running my tennis ball machine recently. This LifeP04 battery is significantly lighter and runs my tennis ball machine perfectly. I wish I made the switch a long time ago. I've only had the battery a short time so not sure about longevity yet. I also purchased the Eco-Worthy charger at the same time. I had an issue with the charger and reached out to Eco-Worthy and they responded timely and resolved my issue. Had they not, my rating would be much different, but I'll support companies that have good customer service and address issues quickly.

Great battery for a DIY solar generator. I made one using this battery and coupled it with a 100 watt solar panel and controller. I found it to be a good value and has good capacity to keep your devices charged. I use it to charge my phone and other power banks. It is very portable, small enough to to carry around with enough capacity to be functional and useful. My DIY solar generator is 256 watt hours using this battery. I have considered getting more to make my generator have larger capacity. You can wire them together to expand the capacity of your generator/power bank. Its Lif04 - Lithium Iron Phosphate chemistry allows 3000-4000 recharges, it should last for for over 10 years. I have been using this battery for a year and a half as of July 2025.
