Samsung 21700 4000mAh 35A Battery
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. 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. 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 4,000mAh in capacity with a 35 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 4,000mAh 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.
