BlackCell Proton 3000mAh 18650 Li-ion Rechargeable Battery (1PC)

Regular price R 160.00 Sale

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.

These cells can handle high amperage and are safe to use in series / multi-cell applications. They can be charged with any Li-ion battery charger with 4.2V output.

    Do not overcharge or over-discharge.

    To combat this, do not leave your batteries in any charger without supervision. Make sure that you are able to see or check on the charger every 15-30 minutes. This way when the charger indicates that the batteries have been fully charged, you can remove them from the charger. Leaving batteries in a charger all night long or longer can cause them to be overcharged, which can result in battery failure. Charging your battery over 4.25 volts can shorten its life-cycle and going over 4.5 volts can cause it to burst. Cease using your charger if this ever happens.


    - Do not use if damaged or temperature is above 212°F/100°C

    - Do not disassemble or modify the battery

    - Do not carry batteries in your pockets or purse

    - Batteries may explode or catch fire if not used correctly

    - Do not discharge batteries beyond the recommended voltage.
