Conclusion

This looks like a good high capacity 18500 battery. It can deliver some current, but it is not a high current batterg

Looks like the best capacity choice of 18500 battery. Shame, gearbest and bangood do not offer anymore. Do somobody know a reliable source?

This battery has been around for a while, I have some too. Good to see that it tests well.
Thanks for the test!

“I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation. And we scientists don’t know how to do that.”   (Gus Speth)
