Security

At full 20A for 10 minutes, the cell reached 70¡ãC. Ok but warm. For intermittent use, it's perfect.
Discharge test gave 1950mAh each, close. For 20A drain, it's acceptable. They do hold 20A without voltage crash.
Matched pair came with same voltage. Using in series for a custom light, no balancing issues. Will buy again.
Swapped my old 20A batteries with these EVE 20P. Instantly better runtime and less sag. They fit perfectly.
I run a Acebeam L35, the 20A battery handles turbo. Replacement for older cells was needed, and these EVE work great.
