Tenpower 40TG 4000mAh 21700 Battery

This battery advertises a 35A maximum continuous discharge rating, however Mooch* recommends limiting to 30A to stay within safe temperature limits.
A little better performing than the Samsung 40T and roughly equal to the Molicel P42A, it's ideal for use with most regulated devices.
Supplied in a protective case.

*The capacity and continuous discharge ratings in the specification above have been verified by Mooch, the most well-known independent battery tester. Since 2015, he has spent countless hours putting batteries through a series of tests to verify (and often debunk) manufacturer's claims about the true capabilities of the batteries we rely on to power our devices safely.
