Material In Use

MWB HC-18650 & 21700 Battery-Packs are manufactured with the highest rated Lithium-Ion cells on the market today. MWB designs and build our own BMS / PCB's that prevents the pack from over-discharging and over-charging. Each pack is welded with .375 Nickel Tabs for the best overall contact between cells, and are tested for high rated charging cycles along with high ambient temperatures. Our standard connector is the 22 gauge 2-Pin JST SM Connector that can be change depending on your needs.

⚠ Important Safety Warnings

  • Inspect Before Use: Always check that the battery terminal insulator is intact and properly positioned. Do not use the battery if the insulator is damaged, missing, or improperly installed.
  • Use Correct Insulators: Only use insulators specifically designed for the battery type (e.g., 18650, 21700). Using incorrect or poorly fitting insulators may leave the terminal exposed and increase the risk of short circuits.
  • Proper Installation: Ensure the insulator is centered over the positive terminal and securely adhered to the battery. Misaligned or loose insulators can expose the terminal and compromise safety.
  • Avoid Damage: Handle the insulator carefully during installation. Do not puncture, tear, or deform the insulator.
