Samsung 20S 18650 2000mAh 30A Battery - INR18650-20S

This cell is the top in terms of current discharge/drain in the 18650 form factor size. It is for Mega-High Discharge/Drain devices only. This cell is the hardest punching cell in the 18650 size class by far all the way until it reaches about 33% drained. With a True 30 amp Continuous Discharge Rating with no temperature cut needed, you can see why that's the case. It also packs a modest 2,000 mAh in capacity as well. However, this cell is only the clear winner of the King of Drain in the 18650 form factor size, when it's used above the 25 amp mark, due to the shortage of capacity needed to sustain it's voltage throughout it's drain. It is an awesome cell when used in device(s) that require or demand more than 25 amps of Continuous Discharge/Drain, this is where this cell's potential is truly unlocked. This power cell does have a moderate range of capacity as well, but not its best strong suit.
