Charging unprotected 21700

Well as I said the cells reviewed by HKJ test well, unlike some Chinese cells.

Some experience of the 21700 provided by Convoy:

There’s reviews of my Convory M21F with the supplied Liitokala 21700 5000 mAh cells showing good performance.

Some older comments:

There been some reports of fake Liitokala cells doing the rounds. Some Chinese brands, Catchfire, Bonfire etc, are awful.
