I bought the 12 Volt 100 AH Lifepo4 Battery I'm very impressed with the Quality of the Battery the Shipping speed. Plus it had a $56 Coupon which made the final price $116.63. That's incredible I'll add it to my Solar system that will give me 800 AHs

Seems well made and I was able to test the rated capacity. Will buy again for sure.

This battery is labeled as 12v 25ah, but according to the user manual it comes with, there are some discrepancies. The manual says 12.8v (which is pretty standard for this type of battery). The manual also states that it’s manufactured as a 12.8v 10ah battery, but later mentions that it’s 12v25ah. The listing says it comes with m8 terminals, but they are actual m5, so a good deal smaller. My test results are closer to a 12.8v 25ah battery, but it’s actually a little higher. I’ll post all the specs and test results below.Measuring the battery, it is coming in at 7wx7hx3d” (and that includes the terminals). It weighed in at 6lbs 4ozs.When I received the battery it was fairly low, but still had a little bit of a charge on it. It measured 12.67vdc. I put a LiFePO4 10a smart charger on it and during the charging it said the battery was at 20%. The charger started at 1.9a and then leached a max current of 9.6a, then dropped back down to 1.4 to finish the last 5% top charge. It was on the charger for a little over 5 hours before the charger stopped. The manual states that 14.6v is the recommended charging voltage, but I was not able to get charging voltage over 13.96vdc. The BMS cut the battery off before I could get there, the voltage spiked at 17.12v, and the charger switched to “off”. With every other LiFePO4 battery I have tested, the charger has been able to reach 14.6v and will indicate “FUL” when done. After charging I let the battery sit overnight and it dropped to a modest 13.72v, which is full. To test this I connected a watt meter and transferred the battery into my delta 2 power station with a constant 100 watt (7.88a) discharge. I was able to pull over 29ah out of this battery which is really impressive considering its 25ah rating. At the end of the test (where the BMs cut power off from the battery), without a load, the battery measured 11.78v.This battery was $79.99 when I ordered it, and it’s $59.99 at the time of this review.I am rating this at 4 stars. I really do like the power it made, and it’s a better deal at $59.99. I don’t like the discrepancies in the manual and listing.

Like the size and it does the job!

I grabbed this for the battery component in a small DIY power station I was building. The size and specs were right where I wanted them.Now that the project is done, it's working great. I did find that the specs were a little off, but this didn't affect my build. Maybe I got a one-off or slightly different SKU or battery? I'm not sure, but it ended up working fine, so that's all I cared about. (For those wondering, the terminals are smaller than indicated and my testing indicates the batter has more capacity than advertised.)After weeks of using it in the power station, the battery has had zero issues, and I'm completely happy with the purchase. I see that the price has dropped and is currently on sale, too. Perhaps now it's time to purchase another for another project!
