12V 20Ah Lithium Battery, 4000+ Cycles 12V LiFePO4 Battery Built-in 20A BMS, Rechargeable 12 volt 20Ah Lithium Battery Perfect for Fish Finder, Scooter, Solar System, Camping

I purchased these to replace the dead batteries in my CyberPower UPS's purchased from Costco. Computer UPS's usually come with Lead Acid batteries that have a short 3 year life, lower 7Ah capacity, and fast discharge curves. These LiFePO4 batteries work, are much lighter, have longer life, and much higher capacities. I improve my UPS's capacity by 40% and don't have to worry about these batteries dying.

I installed this 12.8V 20Ah LiFePO4 battery to replace the 12V 18Ah lead-acid battery that came with my solar-powered chicken coop controller. The original lasted about 8 years, so it'll be interesting to see how long this one holds up. So far, it's been a great upgrade. It fits perfectly, weighs significantly less, and I really like the built-in carrying handle. My coop controller shows it's running at 13.3V, which, according to the battery's manual, means it's charged to around 70–90%. The manual is actually very informative, which I appreciate. Some quick specs worth noting: Battery type: LiFePO4, 12.8V, 20Ah Unit I recieved was 6.1" tall Terminal type: M5 Max continuous discharge current: 20A Peak discharge (5 seconds): 40A Max load power: 256W Operating temperature range: 41°F to 113°F (should be interesting to see how it performs in our cold winters) Charging voltage: 14.3V (±0.2V) Recommended charging current: 4A Note: This battery doesn't provide cold cranking amps (CCA), so it’s not suitable for starting motorcycles or vehicles. Overall, I'm happy with the upgrade. If it holds up through the winter and over time, I’ll consider switching other 12V lead-acid systems over to LiFePO4 as well.

This battery arrived on time and seems solidly built. I am using the battery to power a Garmin fishfinder. I was very pleased that after I installed the battery my Garmin showed that it was receiving 13.6 watts. This should provide optimal picture quality on that unit. I feel like I received great a very good battery at an optimal price.

This battery arrived in perfect condition, partially charged, and then fully charged up quickly. It is now ready to slide into a battery box project. I am very happy with the value. It fits nicely into an Apache 2800 box from Harbor Freight if anyone else is looking for a similar project.

This battery seems to be working well and it charges fine with my trickle charger that has the Lifepo4 setting. I wish it came with insulated caps so that I can screw the terminals on and off without tools. My other battery purchased from Chins had that option so it was a nice quality of life not to needing tools just a screw on a simple wire terminal.

So far this XZNY 12.8v 20Ah battery exceeds my expectations. I have used it mainly to add additional backup battery capacity to my Ecoflow River 3, connected with XT60i to O-ring connectors. It charged my ecoflow at 100 watts charge rate through the solar input port from 0 to 90% in about 2 hours and then all the way to 100% and it still had battery left. I recharged this 20Ah battery in about 2.5 hours with a 10amp LifePo4 charger (avg of 7-8 Amp charge rate). The smart charger said it charged 21.8Ah so I believe the stated capacity is true. So basically for $45 (+$9 cable) I was able to double the capacity of my Ecoflow (added 256Wh). That is a win, and way cheaper than buying an additional battery from your power station brand (or a larger capacity model that costs much more. This XZNY brand was the cheapest of option that had good reviews, and they also offer larger capacity batteries that if you want more battery backup. I also like that it is lightweight and has a small carry handle that makes it easy to move around. XZNY also provides a 3-year warranty period for this battery in case something goes wrong.

2nd Update: After receiving a replacement battery and testing it, it passed with exceptional performance. After fully charging it, I placed a 1.0 amp load on it for 5.0 hours. After resting, it settled at 13.1v, which is 60%-70% SOC. Awesome. Update: While I stand by my original evaluation of the battery, the seller engaged me in an honest technical discussion of my testing process via several conversations. I'm open to admitting my mistakes in exchange for learning. I think they were honestly interested in resolving any issues with their product or my review. Initial review: Fully charged the battery. Applied a 1.0amp load. After 5.0 hrs, the battery, after sitting unloaded for 30 minutes, measured 12.60vdc. At best, this is a 30% SOC. This is barely an 8ah battery, not a 10ah battery.

Tamaño práctico para usarlo en una mochila con mi equipo de RadioAficionado. La he usado con un radio de HF de 100watts por casi 3 horas continuas en TX y sin problema. No he logrado aun agotar la batería en una activación de campo.
