Samsung 40T 21700 4000mAh 35A Rechargeable Battery (40T3)
What makes this cell so special is it's ability of having "Maximum Balance" with Very High Capacity and while having Ultra-High Discharging/Drain capabilities without any compromise, this was previously thought to be impossible as you have only so much room in a cell for either Capacity or High Drain, Not both.
This is the hardest initial hitting cell made that has a legitimate 4,000 mAh or greater in capacity. With this cell 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.
