• Space-Efficient: 30% smaller footprint than cylindrical cells of similar capacity.

✅ Customization Ready

• Flexible Orientation: Can be mounted horizontally or vertically.

• Scalable for 12V/24V/48V Packs (e.g., 4S1P = 12.8V/50Ah).

1. Extreme Discharge Performance

• 70C Continuous Discharge: Supports 1,225A continuous current – one of the highest power outputs in its class.

• 140C Pulse Discharge (10 sec): Delivers 2,450A burst current for peak power demands.

• 3.7V Nominal Voltage | 17.5Ah Capacity (64.75Wh): Optimized for high-energy bursts.

2. Ultra-Low Internal Resistance

• ≤0.5mΩ DC IR: Minimizes heat generation during high-current discharge.

• Voltage Stability: Maintains >3.5V under 50C load, ensuring consistent power delivery.

3. Advanced Safety & Durability

• Thermal Runaway Prevention: Ceramic-coated separator (180°C thermal cutoff) and pressure-activated vent.

• Robust Cylindrical Design: Reinforced casing to withstand vibration and mechanical stress.

• Certified Safety: Complies with UL 1642, IEC 62133, UN38.3 (passes nail penetration and short-circuit tests).

4. Fast Charging & Efficiency

• 5C Fast Charging: 0–80% in 12 minutes (with specialized charger).

• High Energy Efficiency: >95% energy conversion even at 50C discharge.
