Important Notes Before Ordering

60 Days Returns

1-Year Warranty

  • True Capacity (Honest Rating): Verified under a standard test procedure—CC/CV charge to full, then 0.2C constant discharge to the specified cut-off voltage at 25 °C. No inflated numbers.
  • A-grade 18650 Cells, Matched & Balanced: Only A-grade new cells are used. Packs are grouped after dual sorting by capacity and internal resistance (Low IR) to improve consistency and reduce voltage sag.
  • Low Internal Resistance Design: Low-IR cells plus proper nickel strip layout and wiring deliver more stable output under load with less heat—better efficiency and steadier runtime.
  • Professional Build & PCM Protection: 100% functional testing before shipment. The built-in PCM provides over-charge, over-discharge, over-current and short-circuit protection for safer use.
  • Reliable Cycle Life (up to ~800 cycles): Under standard conditions (about 0.5C charge, 0.2C discharge, 25 °C, rated cut-offs), typically up to ~800 cycles to ~80% of rated capacity.*
* Actual results depend on discharge current, ambient temperature, cut-off settings and usage habits. Use within rated limits for best longevity.
