Protected 18650 from Vapcell, these are fairly high current, especially for protected batteries.

The two cells tracks nicely and can easily deliver 10A, at 15A they get hot and the protection will trip after some time.

This test only goes to 15A, this is not enough to trip the protection in a short test.

Here I increased the current at 0.1A each second, and after 198 seconds the over current protection tripped.

Stepping the current faster (0.5A/second), means less discharge and the battery do not get as hot, this means the current limit will be higher.

Conclusion
The batteries looks good, but the over current protection is a bit on the high side and this means the protection circuit can get rather hot.
Notes and links
The batteries was supplied by Vapcell for review.
The spikes in the curves was due to a damaged battery holder. The batteries melted it, before my temperature cut-out activated.

Thanks for this review. At first glance I would guess: 30Q + protection?

Certainly a battery to remember if you are looking for a high drain protected 18650.

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.
