    • Realistically high charge capacity
I was looking for a lot of mAh to power an ESP32 microcontroller with wifi and environmental sensor for a month in the field. This is rated for 8000 mAh. The rate of voltage drop while in use is around one third of the rate for a 2500 mAh battery that preceded this one in the field, implying that the 8000 mAh capacity is reasonable and that the battery should meet my one month service target. (Longevity of course depends on the current demand.) I needed to swap polarity of the wires in the connector to use it with an Adafruit Feather microcontroller. The Amazon product listing for the battery is very clear about the polarity, which is opposite the Adafruit convention. Battery polarity is clear from the colors of the wires. Wish this aspect were standardized. ... show more

Put it on my battery tester, 9072mAh with a 234mR internal resistance. Beware that the pinout was opposite of the Adafruit batteries. It was easy to carefully swap the leads.

    • Be aware! Reverse polarity
I couldn't get the battery to charge or work at all. Upon measuring the voltage and comparing to another standard 3.7V LiPo battery, that the polarity of the wires should be reversed. After swapping the wires, the battery works well. I checked the listing again and on further scrutiny, I noticed the warning to make sure it matched your polarity. Not sure what devices use reverse polarity, but very frustrating. ... show more
