Review conclusion	With reservations	Not recommended

Only in one review: Capacity at high current 3096 mAh (Vapcell F32); Energy 11.33 Wh (Vapcell F32); Resistance 16 mΩ (Vapcell K31 18650); Temperature rise 74 °C (Vapcell F32); Price 14.99 $ (Vapcell F32).

Vapcell F32: The F32 cells handle the rated 10 A well and are consistent, but capacity is only around the stated minimum.

Vapcell K31 18650: Capacity is close to the rating, but parameter variation and increased resistance make these cells a poor choice.
