How to Choose the Right Variant
Measure your original battery (Thickness × Width × Length in mm) and match to the Cell Model or dimensions in the table above.
- Cell Model number is printed on the original battery label (e.g. 606080, 957084)
- Measure T×W×L with a ruler or caliper if the model number is not visible
- Higher capacity = longer runtime between charges
- FCB-CDC1: Igniter/booster clamp accessory only
Applications
- Car jump starters and emergency boosters
- UAV drones and quadcopters
- RC vehicles and aircraft
- Portable power applications
Installation & Compatibility Check
- Verify cell model number: Check the label on your original battery for the cell model number (e.g. 606080) and select the matching variant
- Check dimensions: Confirm the replacement battery fits within the original housing (T×W×L must match)
- Connector compatibility: Verify discharge and balance connector types match your device before connecting
- Polarity: Confirm positive (+) and negative (−) terminals before connecting. Reverse polarity may damage the device
- Power off first: Always switch off the device before replacing the battery
Safety Information
⚠️ No PCM Inside: Use only with devices that have built-in battery protection. Do not use with unprotected circuits.
Charging: Use a compatible Li-Po balance charger for 3S packs. Charge voltage: 12.6V (4.2V/cell). Never leave charging unattended. Charge in a fireproof LiPo safe bag.
Storage: Store at ~11.4V (3.8V/cell) in a cool dry place (15–25°C). Use charger “Storage” mode for long-term storage.
Operation: Do not short-circuit, puncture, crush, or expose to fire. Avoid discharge below 9.0V (3.0V/cell).
Temperature: Operating range: 0°C to +45°C. Do not charge below 0°C.
Inspection: A swollen Li-Po battery is a fire hazard — stop use immediately if swelling, damage, or leakage is detected.
Shipping & Transportation Notice
Li-Po batteries are classified as dangerous goods. Subject to IATA regulations (UN3480/UN3481). Extended delivery times may apply due to customs and carrier handling. MSDS and UN38.3 test report available upon request.
