Enerpower VC+ 18650 3000mAh (Dark green) 2019

Official specifications:

Label and website specify different cell, this makes it hard to know what specifications are valid.

This is a protected cell with good capacity.

The two cells matches nicely.

The protection did not trip at 20A, but the cell got too warm.

I did check the over discharge trip voltage, it was around 2.75V

The internal resistance is low for a protected battery.

Conclusion

The battery works fine and can deliver at lot of current, the do protection will protection the battery from over discharge and short, but probably not from normal overload.
Specifying one type of cell on the website and another on the battery is confusing.

Notes and links

The batteries was supplied by a reader for review.

Thanks HKJ!

I was hoping this would trip the over current at 15A as the website says it should, unfortunately that means it’s not really protecting the battery from over heating? Quite similar to the Keeppower P1831R in terms of circuit protection values?
