Very good Performance. Cheap. Tested up to 2A without issue. No heating up whatsoever.
Not true to rating. Tested capacity is only 531 - 550 mah when discharged from 4.2V to 3V at 1A. Will probably hit 650mah when fully discharged to 2.8V. Still far from the rated 80mah though. Stays at 3.4-3.6V most of the time during 1A discharge so a buck boost circuit board is best.
This is the best 16340 I've tested so far. I've tested many other 16340 (rated at 650 - 1000mah) but none of them came close to this (most have weak output current and not even close to 350mah). And at this pricing, there is nothing to lose when you buy this. You will be surprised at the amount of current this small battery can give out.
