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."

The new smurfs.

These batteries aren't the most amp powerful 30A... but what they lack there, they make up for in capacity..4000 maH these are perfect for 21700 orientated regulated mods... but where I think they shine is in a single coil squonk set up... where current isnt the biggest factor ...

If this is you and your set up... leave the 30Ts for the Cloud heads... and grab a few..

Battery goodness

I never thought I'd be reviewing a battery, but here I am. This is a good battery. You probably won't notice any difference between these and the Samsung 30Ts, but you will when compared to crappier brands (I'm looking at you iJoy).
