Key Performance Highlights

  1. High Power Output: Continuous discharge up to 36 A (with cooling) for very high current applications.
  2. Fast Charging: Supports 3C charging (9 A) when temperature and conditions allow.
  3. Good Energy Capacity: Nominal capacity of 3,000 mAh (typical).
  4. Low Internal Resistance: Very low DC internal resistance (~17 mΩ), leading to reduced voltage sag and heat generation.
  5. Excellent Cycle Life (High Load): Retains ~75% capacity after 500 cycles at 100 W discharge.
  6. Wide Operating Temperature Range: Operable from –40 °C up to +60 °C for discharge; and 0 °C to 60 °C for charge.
  7. High Energy Density: 631 Wh/L (volumetric) and 234 Wh/kg (gravimetric).

Frequently Asked Questions

What are the key electrical and mechanical parameters?

  • Nominal voltage: 3.6 V.
  • Typical capacity: 3,000 mAh.
  • Maximum continuous discharge: 36 A per Molicel spec.
  • Weight: ~47 g.
  • Dimensions: ~18.6 mm diameter × 65.2 mm height.

What is the expected cycle life under high-power usage?

  • Rated for 500 cycles of ~100W discharge + 1C charge, with 75% capacity retention.
  • This makes it attractive for designs that demand repeated high-power cycles, such as power tools or high-performance packs.

What is the cell’s internal resistance?

Very low DCR (DC internal resistance): ~15.39 mΩ, enabling high efficiency and better power delivery.

What is the thermal and operating temperature range?

  • Discharge temperature range: –40 °C to +60 °C.
  • Charge temperature range: 0 °C to +60 °C.
  • The cell is designed with optimized thermal distribution (low hot-spot delta, ~2 °C) to help with high-power usage.
