Rechargeable Li-Ion 18650 21700 60V 20Ah Lithium Ion Battery Pack For 1000w Electric Scooter

Rechargeable Li-Ion 18650 21700 60V 20Ah Lithium Ion Battery Pack For 1000w Electric Scooter

Advantages:

1. High Energy Density & Compact Design

21700 Cell Technology: These cylindrical cells (21mm diameter × 70mm length) offer up to 20% higher energy density than older 18650 cells, storing more energy in a smaller volume.

Lightweight: Reduces scooter weight (e.g., a 60V/20Ah pack may weigh ~5kg vs. 10–15kg for lead-acid), improving portability and handling.

Space Efficiency: Enables sleeker battery designs that fit seamlessly into scooter frames.

2. High Voltage for Enhanced Performance

60V System: Delivers higher power output (P = V × I), enabling faster acceleration, steeper hill climbing, and higher top speeds (e.g., 50–60 km/h for high-performance scooters).

Efficiency: Reduces current draw, minimizing heat loss and extending motor lifespan.

3. Long Cycle Life & Durability

Extended Lifespan: 21700 cells typically offer 1000–2000 charge cycles (depending on chemistry), lasting 3–5 years with regular use.

Deep Discharge Resistance: Tolerates deeper discharges (e.g., 80% DoD) without significant degradation, unlike lead-acid batteries.

4. Fast Charging Capability

Rapid Recharge: Supports high charging currents (e.g., 3–5A), achieving 0–80% charge in 1–2 hours (full charge in 2–4 hours).

Compatibility: Works with standard EV chargers and fast-charging stations.

5. Advanced Battery Management System (BMS)

Safety Features: Prevents overcharging, over-discharging, short circuits, and thermal runaway.

Cell Balancing: Ensures uniform charging across cells, maximizing capacity and lifespan.

​Thermal Management: Maintains optimal operating temperatures (e.g., via cooling plates or vents).
