Only in one review: Voltage 3.6 V (Vapcell T20 21700 2000mAh 40A/60A); Current 40 A (Vapcell T20 21700 2000mAh 40A/60A); Test current 30 A (Sony/Murata US18650VTC4).

Vapcell T20 21700 2000mAh 40A/60A: They deliver up to 40 A well, but 2000 mAh is a low capacity for the 21700 format.

Sony/Murata US18650VTC4: Quality high-current cells; at high discharge currents, their advantage over the Samsung 20S nearly disappears.
