Great battery - if you know it's limitations
Jay (Silver Spring, Maryland) 1/28/2018 2:09 PM
Nice battery pack for low current needs. Not good for hobby motors, but I modified a PIR LED light for my bathroom after having to replace the AA batteries every month. This pack lasted over 9 and 1/2 months of average use by three people coming and going. I have modded two more and will reach for this pack again and again.
Works as advertized

This is a decent battery at a good price. I got 2,158 mA.h from a fully charged battery, discharging at 500 mA and stopping when the voltage dropped to 6 volts. If you go much lower, the protection circuit cuts you off. Although the voltage reads zero, as soon as you connect a charger, you're up and running again. The impedance is not that great, about a third of an ohm.
