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 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.

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.

Battery charged correctly and worked as expected.

I'm impressed - this unit was purchased for a ham radio station. I initially looked at other, more expensive brands, but then found this one, about 20% cheaper than many others, and it had the handle. While the handle is cheap plastic, it makes the battery a lot easier to carry around. Electrically, it performed as expected, and allowed me to have my radio run for 40+ hours while dropping only 0.2V from 13.43 to about 13.23V (i.e., still about 75% capacity). I was mostly listening and not transmitting a lot, so the power draw was limited; however, I am satisfied not having to recharge it. I will keep an eye out for this brand for future purchases.

Really annoying, the situation with two sizes, despite the clear warning in the description, I figured I'd take my chances. I bought two batteries, and got one of each size - one is about a centimeter taller than the other. But... they do both work great, and in this particular application, the size just doesn't really matter - and the price was terrific. So I'm not *really* going to complain. That said, I'm about to build a mobile system that I want the batteries to perfectly swap out with each other, and for that application I'll simply have to go with a different brand/model.

After my first order was "lost" by UPS, I re-ordered and received a replacement battery in 2 days. It was well boxed and packaged and the initial charge state was about 70% (13.2v). Placed the unit on the solar charger in the radio shack and in a couple of hours it was at 100% (13.8v). After disconnecting the battery I monitored the state of charge state for a week and in that time there was no measurable decrease. The following day we had a weather event that required the activation of the EOC (Emergency Operations Center) and our local ARES (Amateur Radio Emergency Services) Net. Because of the severe lightening storms in the area and frequent power surges I opted to use my Go-Box for comms which consists of the XZNY 20Ah battery driving a Kenwood TM-V71 dual band radio. During the 6 hour activation, which included constant monitoring and significant transmission time, the battery's output never fell below 13.4v. After securing the net I decided to experiment further and used the battery to power my Icom IC-7300 for some DX work. I had to reduce output power to 75w to keep battery discharge rates below 18a on transmit but that was still enough to work Europe and South America. After several more hours on the HF rig battery voltage had dropped to about 13.0v (30%) and I decided to recharge the battery. At that rate of discharge it is probable that the battery would easily operate my Go-box for a full 24 hours. I have several other LiFePO4 batteries (full size) but I was impressed enough with the XZNY mini that I ordered another (smaller 18Ah) for a second POTA set up. Impressive battery, great service!

We have a simple solar setup on our popup camper. For the past few years, I've been using a 35-Ah Harbor Freight sealed lead-acid battery that is twice the size, twice the weight, and twice the price. It always gave me trouble charging, didn't last very long, and always died over the winter, even when I kept it topped off. I decided to try something new and bought this when I couldn't get a larger-capacity battery in less than a week before our next outing. It worked fantastically. The solar panel kept it charged and we never ran out of power. My original plan was to get something bigger for next year, but now I'm not so sure I need to. Great experience.

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.
