Product Description
33140 3V 10Ah Sodium-Ion Battery for Electric Bicycles
Key Features
- Enhanced Safety: Sodium-ion chemistry offers greater stability with higher resistance to thermal runaway compared to lithium-ion batteries.
- Excellent Low-Temperature Performance: Maintains over 85% discharge capacity retention at -40°C.
- Long Cycle Life: Designed for 2000-4000 cycles (to 80% initial capacity), reducing replacement frequency.
- High Discharge Rate: Supports 5C to 10C continuous discharge rates for high-power applications.
- Cost-Effective & Sustainable: 30%-40% lower material costs than lithium-ion with more stable supply chains.
