BlackCell’s Proton series batteries are here! The Proton batteries feature an innovative Graphene Li-Ion cell in order 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.
