Only in one review: Voltage 3.6 V (Vapcell T39 21700).

BAK 32140FS-48: The cells delivered nearly their rated capacity and stayed below 60 °C at 40 A; the difference from Gotion is small.

Vapcell T39 21700: The high-current cells showed good capacity and low impedance, but the two samples were not quite consistent.
