Great for QRP portable ops
Great for use with my QRP QMX radio for POTA operations. I like that it's small, lightweight and cabled correctly for my application.

Great battery
Does exactly what I wanted it to but didn't think it would. You know one of those things were you go I hope it works out, and then it does it!! And it does just that ..

Battery pack failed after 3 months of minimal use
Update: seller was very responsive and offered a full refund for the defective product. The battery pack failed after 3 months of minimal use. It will still take a charge but will not power anything. Wiring is intact and there is 0v

Needs alligator clips for testing
Just right for testing 12v DC equipment

Nowhere near 2400mAh capacity
The battery specs stated on the Amazon description are a bit vague, but the capacity clearly is stated as being 2400mAh. Th battery label (clearly shown in the photos) states "Capacity: 2400mAh 26.6Wh"" and "Output: 9-12.6V/2A". The actual capacity is about 600mAh and the output is about 10.7-12.5V. My device draws 163mA. I set my LO BAT indication at 9.5V. As a final design step, I ran a life test on the battery. The battery was fully charged. I even left it on the charger for at least an hour after the charger LED switched to green. The initial voltage was 12.5V, which dropped to 12.3 volts in just two or three minutes, I monitored the voltage at 10 minute intervals. After 200 minutes, the voltage had dropped to 11.210 volts. When I went back 10 minutes later, the battery was dead - 0V. I though maybe I had a defective battery, so I tried the same test with my second battery - with the same results. This time I kept the test under close observation after the battery voltage dropped below 11.5V. The second battery hit 11.210 volts at 205 minutes. By 225 minutes, the voltage had dropped to 10.787V. 23 seconds later, the battery voltage collapsed to 0V like somebody had thrown a switch. When I read the Amazon description again, I realized that is exactly what happened. The description states that the battery has a builtin protection board to prevent over-discharge. I am convinced that this protection board shut off the battery when it had discharged to about 10.78V. That is a long way from 9V, as stated on the battery label. Also, by 225 minutes, I had used only 611mAh of capacity. I am really not happy with this battery.

Stopped holding a charge after less than a year
The battery capcity is now 25% of what it was when first purchased. Doesn't hold enough charge to be useful.
