Are these any good: Skyray SR14500 3.7V 900mAh Li-ion Protected Rechargeable Battery

Hi

I was wondering are the Skyray SR14500 3.7V 900mAh Li-ion Protected Rechargeable Battery sold by tinywind any good and safe to use?

as they have run out of the xtr 14500 and wanted some cheap batterys to use in my AA lights to give abit of boost in output.

For 14500s, I run Sanyo UR14500P 840mAh unprotected cells. They are at the top of the heap. You can find them with PCB protection circuits, that may, or may not, be too long for you light, offered by people like KeepPower and Orbtronic for <$8.
