18650 7.4V 1700mAh Sodium-Ion Battery Pack

Features

1. Inherent Safety: Sodium-ion chemistry is often considered less prone to thermal runaway compared to some high-energy lithium-ion chemistries, contributing to enhanced safety.

2. Excellent Low-Temperature Performance: Typically maintains better performance than lithium-ion batteries in low-temperature environments (e.g., -20°C).

3. Fast Charging Capability: Supports relatively fast charging, potentially up to 1C or higher.

4. Abundant Raw Materials: Utilizes sodium, which is more abundant and geographically widespread than lithium, potentially leading to better supply chain stability and lower long-term costs.

5. Environmentally Friendly: Some chemistries can be made from more environmentally benign materials.

Specifications

Applications

• Portable Electronics: Power banks, portable speakers, and other consumer devices requiring moderate power.

• Power Tools: Suitable for a range of cordless tools such as drills and saws, benefiting from the high discharge current capability.

• Emergency Lighting & LED Lamps: Used in emergency lighting systems and LED照明.

• Small Energy Storage Systems: Applicable in small-scale energy storage applications, such as backup power for electronic devices or integration with solar panels.

• Electric Toys: Used in electric Toys.

Warnings & Safety Instructions

Charging

• Use Designated Chargers: Charge only with a charger specifically designed for sodium-ion batteries with the correct voltage (e.g., 8.6V-8.8V for a 7.4V pack) and current limits. Using a charger for other battery chemistries (e.g., Li-ion) is unsafe.

• Temperature Control: Do not charge outside the specified temperature range (0°C to +55°C). Charging outside this range may cause damage or hazard.

• 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 (approx. 5.6V-6.0V for the pack). Deep discharge can damage the battery.

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

• Temperature: Avoid discharging at temperatures beyond the specified range for optimal performance and safety.

Storage

• Ideal Storage Charge: For long-term storage, it is recommended to store the battery at a state of charge between 30% and 50%.

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