Samsung 21700 Battery 40T 

As one of the top-performing 21700 batteries from Samsung, the 40T (INR21700-40T) offers 4,000mAh in capacity with a 30A maximum continuous discharge.

Samsung has really hit some “Grand Slams” just in the past couple of years with Li-Ion cells. This Samsung 40T is just one of those examples!
However what makes this cell so special is it’s ability of having “Maximum Balance” with Very High Capacity. Featuring Ultra-High Discharging/Drain capabilities without compromise. This was previously thought to be impossible as you have only so much room in a cell for either Capacity or High Drain. Samsung have proved the impossible, possible with this cell.

Samsung has become the leader in the R&D department as of lately, this Samsung 40T is just one shining example of that. Having a legitimate 4,000 mAh in capacity with a 30 Amp True Constant Discharge Rating without involving a temperature limit cutoff and not making the cell over worked, is nothing short of Amazing.

This is the hardest initial hitting cell made that has a legitimate 4,000 mAh or greater in capacity. Now you can have a true “Peace of Mind” that your demanding needs and wants will be more than satisfied and met with no problems. This is a truly a Phenomenal cell in the 21700 form factor size.

The twin brother to the 30T, the 40T lasts a bit longer in the ring but hits a bit less hardcore than the 30T. It’s a great battery, endorsed as one of the best by Mooch. Especially excellent in regulated mods for the best in class capacity they provide, without compromising on output too much!
