The Efest Double Battery Case can store two 20700 batteries or 21700 batteries, matching security with high-quality production.
The double-compartment design ensures that the batteries will not come into contact with each other when stored. The soft plastic shell of each compartment is removable, with a secure seal on each to stop them coming loose.
We never recommend you keep batteries loose, when transported or stored, they should be done so in a dedicated case.
