Product Description
18650 7.4V 1700mAh Sodium-Ion Battery Pack
Features
- 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.
-
Excellent Low-Temperature Performance: Typically maintains better performance than lithium-ion batteries in low-temperature environments (e.g., -20°C).
-
Fast Charging Capability: Supports relatively fast charging, potentially up to 1C or higher.
-
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.
-
Environmentally Friendly: Some chemistries can be made from more environmentally benign materials.

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.
