Key Performance Highlights
- Very High Capacity: Typical ~5,300 mAh, with a minimum rated capacity of ~5,140 mAh.
- Nominal Voltage: ~3.63 V.
- Long Cycle Life: Rated to retain ≥ 80% capacity after 1,000 cycles (at 1C charge / 1C discharge under specified conditions).
- Moderate Discharge Capability: Max discharge current up to 3C (~15.9 A) per spec (not recommended continuously for cycle-life).
- High Charge Current: Supports up to ~5,300 mA charging (though not for long-term cycle use).
- Wide Operating Temperature Range: Charge 0°C to 45°C; Discharge –20°C to 60°C.
- Low Internal Resistance: Initial AC resistance is very low (≈ 13 mΩ per vendor spec) helps with efficiency and heat management.
- Robust Energy Density + Stability: Designed for applications needing high energy storage with reasonable current draw, such as e-bikes, energy storage systems, and high-capacity power packs.
