Samsung 40T 21700 4000mAh 35A Li-Ion Battery

(12 customer reviews)

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.
