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

This 12-volt battery offers reliable power and consistent performance, making it a solid choice for a variety of applications. Its compact size and durable construction are notable, and it holds a charge well even after extended periods of disuse. Whether you need it for automotive, marine, or off-grid power, it delivers dependable results.

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!

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.

I wanted to share my experience with the XZNY 12.8V 20Ah LiFePO4 battery I purchased off Amazon.I know it's only April, but around my house it's always Halloween, so I purchased this battery in early March in the hope that it would power a tricycle for several hours as it went around a track. I originally purchased a 12v motor that looked like it would work, and didn't draw too many amps, so I figured the XZNY battery would be able to power it throughout the day without needing to be recharged.Unfortunately, while the battery did power the motor, the motor was not powerful enough to work in my application. So, having worked with windshield wiper motors for other props (those being powered through a regulator), I knew that motor would have enough power to move the trike, but wasn't sure on the amp draw it would take to power everything plus the weight of the battery. So, seeing as how I already had everything pretty much ready to go, and only needed to make a few modifications to allow for the size of the new motor, I took a chance and hooked everything up.As soon as I connected the last wire to the battery, the front wheel of the trike lifted off the ground, and moved way faster than I expected!! Success!! Now for the real test... I needed a battery that would power the trike for at least 8-10 hours so I wouldn't need to stop it throughout the day for a recharge, and on a small trike, there’s not enough room for 2 large batteries. So, I set up a small track loop, placed the trike on it, and started the timer. WOW!! I was hoping for 8-10 hours, and on low speed, this battery powered the trike for over 13 HOURS STRAIGHT!!I ran the battery until it was depleted, recharged, and repeated this process several times. Each time with the same result! I then changed the configuration to run the motor on high speed. I knew this would severely impact the battery life, but even on high speed, the battery powered everything for over 7 hours!! I’ll admit that for the high speed test, the trike was on unlevel patchy ground, so that made the motor work harder and draw more amps, but still, 7 hours straight was still very good!My next addition is to add some LED lights to this thing so you can see it in the dark, and while I have a converter to go from 12v-5v, I’m going to have to see how running the lights impacts the performance of the battery. But, I’d only be powering the lights for 3-4 hours, so hopefully things will still work out. If not, I’ll have to either grab a 12v 30Ah battery for the whole setup, or add on a 12v 6-10Ah battery to help power the motor longer and have the lights stay on.Okay, so would I recommend this battery to others – 1000% YES! Far outweighed my expectations, especially considering that I wasn’t planning on powering a beefy windshield wiper motor for this project! I LOVE the screw terminals, and while you wouldn’t think a handle on a battery would make too much of a difference, in my application, it was HUGE!! Having to put the battery in a compartment, and lifting it in and out of there many times was so much easier having that handle! The weight of the battery coincides with the power it provides, although if there was a shorter version of the 20Ah battery, it would have worked a little better for me, especially considering that I’ll probably need to add a smaller one depending on the light situation.I’m so glad that your batteries popped up in the Amazon search!

I though it came with a bag. It was just the battery in the box. I was counting on the bag to be there.

has more power than stated, fits into large ammo box. arrived perfectly and is exactly as advertised

It has on cold cranking amps can not you to start a lawnmower

Nice size that fits nicely in an apache 5800. The three year free replacement warranty sounds great. Only thing I would change at this point is some type of capacity/voltage readout for quick battery life visual.
