33140 3V 10Ah Sodium-Ion Battery for Electric bicycles

Features

1. Enhanced Safety: Sodium-ion chemistry is generally considered more stable and less prone to thermal runaway than some high-energy lithium-ion chemistries, offering higher resistance to overheating and related safety issues .

2. Excellent Low-Temperature Performance: Maintains strong functionality in cold environments, with discharge capacity retention of over 85% at -40°C .

3. Long Cycle Life: Engineered for long-term use, with a cycle life of 2000 to 4000 cycles (to 80% of initial capacity) , reducing the frequency of replacement.

4. High Discharge Rate Capability: Supports high discharge rates (5C to 10C continuous) , making it suitable for applications requiring high burst power.

5. Cost-Effective & Sustainable: Sodium resources are more abundant and widely distributed than lithium, leading to lower material costs (typically 30%-40% lower than lithium-ion) and a more stable supply chain .

Warnings & Safety Instructions

Charging

• Use Designated Chargers: Charge only with a charger designed for sodium-ion batteries with the correct voltage and current limits.

• Temperature Control: Do not charge outside the recommended temperature range (ideally 0°C to +45°C). Charging in extreme temperatures can cause permanent damage or hazards.

• Voltage/Current Limits: Do not exceed the maximum charge voltage or current.

Discharging

• Voltage Limit: Do not discharge the battery below the recommended cut-off voltage (≥1.5V). Deep discharge can irreversibly damage the battery .

• Current Limit: Do not exceed the maximum continuous discharge current.

• Temperature Monitoring: If the battery becomes excessively hot during use, stop operation and allow it to cool down.

Storage & Disposal

• Ideal Storage Charge: For long-term storage (longer than one month), store the battery at a state of charge between 30% and 50%.

• Storage Environment: Store in a cool, dry place away from direct sunlight, heat sources, and moisture. The recommended storage temperature is typically -20°C to +35°C.

• Disposal: Do not dispose of in regular trash. As a rechargeable battery, it must be recycled or disposed of according to local regulations at designated battery recycling centers.
