PROTON 18650 3018mAH 2pk By BlackCell

BlackCell's Proton series batteries feature an innovative Graphene Li-Ion cell to produce the best conductivity and maximum charge speeds possible. Unlike other 18650's on the market, all BlackCell batteries come with a secondary ventilation system on the base, designed to deform in the event of the top vent failing.

This pack includes 2 high-capacity 3018mAH batteries, perfect for high-drain devices that require reliable, long-lasting power.
