3.7V 3000 mAh Lithium Batteries 18650-1S2P-3C

3.7V 3000 mAh Lithium Batteries 18650-1S2P-3C
  • Parallel Capacity Scaling: Two cells in parallel to achieve a robust 3000mAh.

  • Advanced Cell Matching: Both cells are meticulously matched for resistance and capacity.

  • Precision Spot Welding: Pure nickel strips ensure a low-resistance, durable connection.

  • Shared Current Load: Parallel design reduces stress on individual cells, extending pack life.

  • Reliable PCM: Protects both cells equally against over-charging and discharging.

  • Stable 3.7V Output: Keeps your device’s power system simple while increasing endurance.
