EVE INR21700 50PL 3.7v 5000mAh Li Ion 21700 Battery Cell 125A Low Internal Resistance

Engineered for high-demand power applications, the EVE INR21700-5000 50PL redefines performance standards with its exceptional energy density, ultra-low internal resistance, and extreme discharge capabilities. Ideal for electric mobility, power tools, and energy-intensive devices.

1. Unmatched Power Density & Capacity

• 5,000mAh (18.5Wh) Capacity: Highest in-class energy storage for 21700 form factor.

• 50A Continuous / 80A Pulse Discharge: Sustains high-current demands without voltage sag.

• Energy Density: ≥250Wh/kg, outperforming mainstream competitors (e.g., Samsung 50E: 240Wh/kg).

2. Ultra-Low Internal Resistance (IR)

• ≤12mΩ DC IR (25°C): Minimizes heat generation, boosts efficiency by 15% vs. standard Li-ion cells.

• Voltage Stability: Maintains >3.2V under 30A load (90% energy utilization).

3. Long Cycle Life Under High Stress

• 1,200+ Cycles (to 80% capacity @ 1C/1C, 25°C) – even at 3C discharge: 800+ cycles.

• Low Self-Discharge: <3% per month (vs. 5–8% for NMC alternatives).

4. Enhanced Safety Architecture

• Triple-Protection Design: Integrated CID (Current Interrupt Device), PTC, and venting membrane.

• Stable NMC Chemistry: Passes nail penetration (150°C max. surface temp) and crush tests (UN38.3 certified).

5. Wide Operating Temperature Range

• -20°C to 60°C: Delivers >65% capacity at -20°C (with pre-heating support).

• Optimized Thermal Management: Ceramic-coated separator prevents thermal runaway.

⚡ High-Performance Power Tools

• Sustained Torque: Drills/saws maintain peak power under load (30A+ bursts).

• Fast Charging: 2C charge (0–80% in 25 mins).

Electric Mobility & E-Bikes

• 48V/60V Packs: 13S4P config delivers 2.6kWh, 100km+ range @ 750W motor.

• Hill-Climbing Support: Stable voltage at 25A continuous discharge.

✈ Drones & UAVs

• Payload Capacity Boost: 20% longer flight time vs. 4000mAh cells.

• Instant Thrust Response: <0.5s voltage recovery after 80A burst.

Portable Power Stations & Medical Devices

• High Efficiency: >95% energy conversion in backup systems.

• Low Noise: Minimal heat dissipation fans required.
