I use this battery to power a Minn Kota 45lb thrust trolling motor and it performs very well. It will push a loaded canoe faster than we can paddle for many hours. Back at camp I recharge it with a 30 watt solar panel/charger and always have enough juice for more boating. I highly recommend this product and have had good experience with other Eco-worthy items as well, especially for their price point. Ben in Western Washington

bought on sale and got a great deal. It was actually the same price and replacing my lead-acid RV battery, so the switch over was a no brainer. The battery is very light, and was a direct replacement with my power converter. The app loads up quickly and cleanly, and allows you to look at every aspect of the battery, including the individual cells. So far, a perfect replacement for an aging AGM. The only "ding" on the battery.. it was sent with a full user manual for the APP, but not one for the battery itself. The battery manual has to be downloaded from Eco-Worthy's website.

This battery is well made and looks like a quality product. My initial impression is positive, although there are some things to consider. The battery has a display using single LEDs that show the state of the charge as well as other monitored events. This particular battery is supported by an app that communicates with the battery via blue-tooth. I found that the display, at least where the state of charge is concerned is overstated. My battery showed a 50% state of charge out of the box, yet based on the required time to charge it to 100%, it was likely only charged to about 30%. I think the phone app might be more accurate but the jury is still out as I experiment with the app. The one thing I miss on this battery is an easy means to transport it. It has no strap of other means to carry it except a handhold on each side. Since it weighs only 29 pounds, it could be easily carried if it had some sort of a system built in. In it's present configuration you have to use both hands to transport it.

I bought the ECO-WORTHY 12V 100AH LiFePO4 Lithium Battery for a project that required a reliable 12V power source. This battery not only meets those needs but exceeds expectations with its advanced features. One standout aspect of it is the Bluetooth connectivity, which allows me to monitor the charge state seamlessly from my smartphone, a truly impressive feature that adds convenience and control over my setup. The only aspect that left me wishing for more is the lack of information on how to develop an application to communicate with the battery directly. Access to such resources would allow for deeper integration into my project, enabling real-time monitoring and control within a custom app framework. Despite this, the battery's overall quality and functionality make it an excellent choice for anyone needing a dependable 12V power solution with modern connectivity features.

This is a review of an ECO-WORTHY 12V 100AH LiFePO4 battery. Short report: The battery's initial performance is as specified. The company's service and technical support is exemplary. More details: The battery was delivered Aug 22, 2023 and put into service the nest day. This report is being written on Nov 21, 2023. Although we are off-grid solar, this battery was purchased to provide a power source for a 2 kW inverter (Harbor Freight) and various 12V pumps (Northern Tools) for our irrigation system. The inverter is used to power a small, portable air compressor, a sump pump (to transfer water between IBC totes) and a Worx electric leaf shredder. The battery is excellent for powering the pumps. It empties a 275 gallon tote many more times than the 100 AH AGM battery that it replaced. I did not make careful measurement of the AGM battery so a quantitative comparison is impossible at this point. With the ECO battery, it was necessary to add a pressure restriction for my over head sprinkler to function properly. This higher pressure was not an issue with the AGM battery. I have not had occasion to test the sump pump yet. The leaf shredder draws 8A at 120V which will be 80A at 12V. Harbor Freight claims their inverter is 80 - 90% efficient depending on load. Taking the lower number, this means the battery is being loaded to approximately 100A with surges when the shredder is heavily loaded. TO BE CLEAR, the ECO-WORTHY technical staff do not recommend loading the battery this way, as they expect it to shorten battery life. I am 78 years old and can only hope this limitation is significant for me. YMMV. How much usable power does this battery produce? I started with a fresh, fully charged battery charged with a LiFePO4 charger. Using the HF inverter, I connected a Kill-A-Watt meter to the inverter then the Worx shredder to the meter. The shredder pulled approximately 8A at 113-114V with no material entering the shredder. Under load, the current increased to approximately 10A with occasional spikes to approximately 12A. I ran the shredder until the inverter low voltage protection shut the inverter down. At this point, the Kill-A-Watt meter indicated 1.05 KWH had been produced. The battery measured 11.10V suggesting approximately 7 AH remaining charge. A 12V, 100 AH battery should produce 1.2KWH power. The side of the battery lists 12.8V, corresponding to 1.28 KWH. The specifications on the inverter are 90% efficiency at light load and 80% under heavy load. The Kill-A-Watt meter recorded 1.05 KWH after the current passed through the inverter. The actual battery capacity was calculated for 80%, 85% and 90% inverter efficiency and 12.0V and 12.8V nominal battery capacity: Meas KWH 1.05 Inverter Eff 90% 85% 80% 1.155 1.2075 1.26 Battery Volts 12V 96.3% 100.6% 105.0% 12.8V 90.2% 94.3% 98.4% The unaccounted power losses include the 1.5A Harbor Freight claims their inverter draws anytime it is on including the time I was reloading my cart. Since the inverter was heavily loaded when shredding, I think it is safe to assume overall losses were approximately 20%. My conclusion is the battery met its capacity specs within the limits of this measurement. ECO-Worthy has provided excellent customer service. The first time I used the battery to power the leaf shredder, I used a set of heavy duty clamps to attach the battery to the inverter. After an extended period of operation, the positive terminal softened the battery case resulting in the terminal settling. I contacted Eco-Worthy and informed them of the problem. Within 12 hours, I received an email requesting a photo. Within 12 hours of submitting that photo, I received a message informing me they would replace the battery and requesting more details about the circunstances. The re[placement battery arrived 9 days later. It was in transit for 7 of those days. Responding to their interest in the field performance of the battery, we have corresponded a number of times. These guys know what they are talking about and have demonstrated an interest in understanding how their product is used and a willingness to stand behind their product. Why did I buy this battery in the first place? There are three reasons: (1) It weighs 23 lbs, not the 65 lbs of an AGM battery. (2) This battery has a three year waranty compared to the one years of the AGM batteries on Amazon, (3) AGM batteries can be discharged to only 50% State of Charge (SOC.) The LiFePO4 batteries can be discharged to 20% or lower without affecting battery life. At current Amazon prices, the least expensive AGM battery is $3.20/usable AH whereas the ECO-Worthy is $3.50/ usable KWH. That is, the battery has 3x the warranty for a price difference < 10%.

These are really excellent batteries for the price. I have three of them in parallel being charged by a Renogy 400W solar system and feeding a 2kW inverter. They are in a shed that sees 20 to 120 degrees F and they have been in use 24/7 for a whole year without any signs of degradation or wear. They replaced lead acid batteries and they have significantly more useful capacity and low internal resistance. You can pull 100a out of them without overheating them.
