## Description

12V 20Ah Lithium Battery LiFePO4

Review: Works great with my solar-powered chicken coop controller - 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.
Review: Great & cheap way to add extra capacity to your Portable Power Station! - 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.
