Key Performance Highlights

  1. High Energy Capacity: Rated standard discharge capacity is ~3,350 mAh.
  2. Nominal Voltage: 3.6 V.
  3. Moderate Continuous Discharge: Supports up to ~8 A continuous current.
  4. Good Mid-Drain Performance: Maintains ~95% capacity even at 2C discharge (≈6.8 A).
  5. Cycle Life: After 500 cycles (at ~1 C charge / 1 C discharge), capacity stays ≥ ~2,010 mAh (~60% of original).
  6. Recovery After Storage: Recovers at least ~2,680 mAh (80% of capacity) after 30 days at 60°C.
  7. Low Internal Resistance: Nominal AC impedance is ≤ ~35 mΩ, which helps reduce heat.
  8. Reliable Packaging: Typical cell weight ≤ 50 g; dimensions: max dia ~18.55 mm, height ~65.25 mm.
  9. Wide Operating Temperature Range: Charge: 0–45°C, Discharge: –10–60°C.

Frequently Asked Questions

What is the maximum continuous discharge current?

  • The continuous discharge current is 8 A.
  • There is also a 13 A pulse/discharge peak, but that is not for continuous operation.

What is the recommended charging method?

Use CC/CV (constant current then constant voltage) charging.

Standard charge current: 1,700 mA (0.5C) to 4.20 V.

For longer cycle life, charge at 1,020 mA per the datasheet.

What are common use cases for this cell?

Energy-storage systems, e-bikes, power tools (with moderate current draw), portable electronics, and other applications that benefit from high capacity and relatively stable mid-drain performance.

What should I watch out for when using in a pack?

Because continuous discharge is only 8 A, it may not be suitable for very high-current power tool packs. (Some users note this vs other cells.) > “I would go with the 30Q… the 35E has about half the continuous discharge rating of the 30Q”

Make sure to balance cell matching, use proper BMS, and avoid deep discharging below safe limits.
