Battery Storage Case
Vapcell Battery Storage Case
Made for Lithium batteries. Best to store in a case to stop short circuits or wear of the outer wrapper. Lithium batteries can be extremely dangerous if mishandled
Designed for 2x 18650 batteries
Also shown fitting 1x 26650 battery and 2x 21700 (not protected). It's a tight fit for the 2x 21700 batteries, but still fits. The 21700 are the Molicel P42A at 70.00mm length.
Much better than those cheap plastic cases that often break at the hinge or clips.
The yellow colour may appear different in person or on your device's screen since all screen colour settings are different.
