Good cell. Very high drain rate, stays cool.

If your device cannot accept a Nitecore NL1834 and you need a faster drain rate than other cells, this is a good value battery for higher capacity with good high drain rate staying cool for charge and discharge.

Having great luck with Efest purple 18350 batteries in the past I made a purchase of a small batch of 18650's from Battery Junction. I used them quite a bit in the short time since purchase. After breaking them in I ran the batch through my battery analyzer and charged, discharged, tested under load and checked for capacities. The consistancy between cells was excellent and the capacities were all over 60 MaH higher than spec (3500 maH, 20 Amp high discharge currerent). They were at a great price too.

I do like these batteries and haven't had any issues with them. However, there are some other brands and even other Efest cells that have a higher constant discharge with a 3000+mah rating.
