I didn't need these batteries but I owe it to them for refunding it and letting me keep them so I'll rate 5 stars

Use it for my underwater camera ice fishing. Lasts way longer than the lead acid battery that the camera came with and love how much less it weighs. Great value for the money. Ordered a second one.

I purchased this battery at the end of Oct 2022. It pulled full capacity and worked as described.This summer the battery became very hot. Seemed as if there was a short causing the cells to overheat and discharge to near 0 volts. It would no longer work properly and had failed. I contacted customer support and the were very good. I described the failure and provided pictures of the cells and BMS. The attached picture shows the BMS and cell configuration (the sloppy soldering at the BMS was my doing). The battery construction was very good with spot welded nickel to the cells and to the BMS. They got back to me and said that they would send me a new battery! Impressed!The only negative about this battery is that it does not have over temperature protection ( the ad indicates that it does). The BMS does not have a thermistor for temperature sensing.In my experience this battery was a good purchace and the customer service proves that they are willing to honour the warranty...

My old lead acid, 36Wh battery which "tested good" but only gave me 2 minutes runtime before shutting off (at 72 watts load), is what this replaced. I stopped the timer after 21 minutes because the battery percentage never left 100%, it's obvious that this battery is far superior to the old lead acid UPS batteries that this is meant to replace. I have a 3x battery, rack mount UPS that three of these are going into, on top of the one I installed in my consumer grade Cyberpower (for my desktop workstation). I have high hopes for these! Absolutely awesome.Update(Dec5,2023): after 3 months of use in a server UPS (with a very light load), these batteries shorted and nearly caused a fire. I woke up one day to a putrid smell all over my house, and in the picture, you can see the damage.
