Samsung 21700 40T Battery

This is the best battery on the market for regulated devices pulling up to 25A (up to ~75W).

This battery provides incredible performance for both regulated and mechanical devices, but truly shines when using a regulated device, with incredible battery life. 

 

Please see Mooch's review of the Samsung 21700 40T battery here.

"This cell outperforms every 18650 and 20700 in regulated devices at up to about 20A-25A (60W-75W). Only the Samsung 30T hits harder for 21700’s ...
At above 20A-25A (60W-75W) the Samsung 30T is the better performer anyway. The 40T is best at low to mid power levels where it can be the most efficient."
