Nitecore NL1829LTHP Low Temperature Li-ion 18650 Battery.

The Nitecore NL1829LTHP is an 18650 Li-ion battery that can be used in temperatures as low as -40ºC, making it ideal for use in severe environments. The cell has a high discharge of 8A which makes it suitable for high performance flashlights, such as the Nitecore Concept 1, HC33 and TM28. 

The battery has a range of internal safety features including a pressure relief valve which activates in the event of a rapid temperature increase, a microporous barrier to protect delicate internal components and built-in PTC which inhibits high current surges. In addition, the 18650 has an integrated high performance protected circuit which protects against overcharge, over discharge and short circuiting.

I have not had a chance of testing this battery at low temperatures. Otherwise, it looks very well built and it works well at room temperature (being able to power a 1800 lumens torch).
