Excellent cells, will buy more!

I purchased 2 of these cells separately, a week or so apart. First one measured 3.65V when I received it, second one was unfortunately overcharged at 4.23V. Both cells were around 4.2Ah on my CC load tester @ 5A load. I regularly subject these to sustained 11A+ loads in my Convoy M3-C for up to 10 minutes, and these definitely are excellent cells for high powered flashlights.

Please DON'T stock these with such a high state of charge!

High Drain Battery 21700 4000mah 35A

A solid, robust and well made battery capable of handling High Drain devices with ease. I torture these batteries in a application that normally requires a High Drain Lipo battery, upwards of 65A - 100A. While these will not handle such a high amperage draw they do easily sustain a constant draw of 25A+ with peaks out to 40A in short bursts. Voltage sag is minimal compared to other Li-ion brands and they do not produce high temperatures when used in this way (heat means lost power). The cells can and have been taken as low as 2.8V without damaging them allowing the use of the maximum amount of stored energy which means longer use/time from them between each charge.
They are equal to and in some cases better than the four Big Li-ion Battery Brands.
The cherry on this cake is that VAPO supply these cells at a very reasonable price when compared to other suppliers.
