**Please note these 4000mAh batterys have the far superior 21700 type cells you will find that most that are being sold are using the lessor 18650 Cells
The stronger heating and lower resistance of 21700 cells than the 18650 results in higher polarization in the 18650 and deviations between the voltage curves for the two formats at higher C rates. The 21700 has about 50% greater capacity and energy density than the 18650 for discharge rates up to about 3.75C.
As the old saying goes, You get what you pay for
Massive 4000mAh dont run out of charge again with this massive capacity !
