Samsung has made some really impressive innovations with renewable technology in the last couple of years with Li-Ion cells, and the Samsung 21700 40T rechargeable battery is one great example.
What makes this battery cell so special is the ability to have “Maximum Balance” with Very High Capacity while also having Ultra-High Drain/ Discharge without any compromise. This was previously thought to be impossible as there's only so much room in a battery cell for either High Capacity or High Drain, not both.
This is the hardest initial hitting battery made that has a genuine capacity of 4,000 mAh or greater. With this battery you get peace of mind that your demanding needs will be satisfied with no problems.
The Samsung 40T rechargeable battery is a truly a phenomenal cell in the 21700 form factor size.
