[size=+3]Keeppower 18650 3000mAh P1830R (Black) 2017[/size]
Official specifications:
This is a high current protected 18650 cell from Keeppower
Very good tracking in the discharge curves.
The cell gets rater hot at 15A
At 20A I stopped the test due to temperature.
This test only goes to 15A and did not trip the build in protection.
Protection will usual trip on 3 conditions: Over current, over charge and over discharge.
[size=+3]Conclusion[/size]
This is a good cell, but the build in protection do not trip on overload (It will probably trip on higher currents).
[size=+3]Notes and links[/size]
The battery was supplied by Keeppower for review.
How is the test done and how to read the charts
How is a protected LiIon battery constructed
