Review: Spec check... A.O.K., a nice thumbs-up on this 12V 12Ah LiFePO4 - Whether you're looking to power your kid's toy, auxiliary power for camping, or trying to put together a UPS, shopping for batteries can be a pain. While putting together your own UPS might require reliable specs, more so than toys or camping, everyone should feel it's reasonable to receive what a seller claims in their ad. In a nutshell, this battery nicely ticks all of the boxes. So, let's get to the deets! The battery arrived holding 13.24V, which is pretty typical. It received a full charge and I let it sit for 30 minutes before load testing. .2C test performed, which basically means you attach the battery to a load equal to 20% of the rated amp hours, which in this case is 12Ah, thus 2.40 amps. This battery did very well. There shouldn't be a steep curve in the discharge. Still, here's the hourly breakdown, so you can see exactly how well this battery held above 12V. The results over the five hours: At start, no load voltage settled at 14.3, connected to test equipment and within 5 minutes, voltage settled to 12.9V Hour 1 - 12.8V Hour 2 - 12.8V Hour 3 - 12.7V Hour 4 - 12.5V Hour 5 - 12.0V And beyond - Voltage dropped to 11.9V at 5hr 10min. Since there's a BMS (battery management system), I always let the test run so I can confirm the over-discharge function is working. The battery continued to provide power for an additional 30 minutes. The manual shows the over-discharge limit is set at 10.4V, however the BMS cut off at 11V. I have no issue with this. Battery protection is in place and functioning, which will contribute to longevity and prevent some of the irreversible damage that can happen in this type of battery. As expected, the voltage dropped from 12.0V at 5:10 to 11.0V at 5:30. Test was completed at 63°F, roughly 17°C, and the battery stayed cool to the touch. Beside the over charge and discharge functions, the BMS also provides over-current and short-circuit protection and high and low temperature protection. I don't experience the temperature extremes where I am, so I don't test for them. The user manual provided is quite good. I'm including a picture of a page showing my test matches the manufacturers curves. I'm glad to own this little power source and will put it to good use in a portable UPS I'm building. The price at the time I ordered it was $44.79, which is very close to what I see it's selling for at the moment. That's a mid range price for a 12Ah 12V LiFePO4, but it's actually pretty inexpensive for one that ticks all of the boxes, so it's a definite 5 star value, from my perspective. I have no way to quickly test the claim of 6,000+ discharge cycles. That puts it in the range of 10+ year batteries. Good stuff. * Note the picture showing the test equipment shows the voltage at the start of the test. Both the multimeter and the load device read 12.9V, but the LED display pulse makes it difficult to capture what the eye actually sees, which was 12.9V and 2.40 amps.

### ⭐⭐⭐⭐⭐ Meets amp hour specification, great compact battery
*by M***V on November 27, 2023*

I'm going to use this for garage lighting at my off grid camp. My needs are pretty small and this is just the perfect size for this application. Have been disappointed with the life of lead acid SLA batteries, this should be maintenance free. It comes with the best manual I have seen with a lithium battery giving all the charts for discharge rates etc for those who are technically minded. The internal BMS makes this a foolproof battery preventing over charge and discharging too deep. Overcurrent disconnects battery till load or short removed. Pictures show the AH and voltage at that time till the battery disconnects. Discharge rate was 3A. Last picture shows it took 11.99AH to fully charge and disconnect from charging. #1 4.10AH 12.8V #2 6.0AH 12.7V #3 8.0AH 12.5V #4 11.12AH 11.9V #5 11.88AH 10.8V I was going to include a video of test procedure and do a second test. Unfortunately, in moving wires around an errant wire slipped into an opening in the power meter case and zapped the factory programming pins. This was an expensive test for me! This is a good battery that meets the specifications.
