2. Safety Information
Lithium Polymer (LiPo) batteries are powerful and require careful handling. Failure to follow safety instructions can result in fire, personal injury, and property damage. Always prioritize safety.
- Charging: Use only a LiPo compatible charger with a balance function. Never charge unattended. Charge in a fire-safe area, away from flammable materials.
- Storage: Store LiPo batteries at room temperature, in a dry place, and at a storage voltage (typically 3.8V-3.85V per cell). Do not store fully charged or fully discharged.
- Handling: Do not puncture, disassemble, short-circuit, or expose the battery to extreme temperatures or direct sunlight. Avoid physical impact.
- Discharging: Do not over-discharge the battery below 3.0V per cell. Over-discharging can permanently damage the battery and create a fire hazard during subsequent charging.
- Damage: If the battery becomes swollen, damaged, or shows any signs of abnormality, discontinue use immediately and dispose of it safely according to local regulations.
- Disposal: Never dispose of LiPo batteries in regular trash. Consult local regulations for proper disposal of LiPo batteries, often involving specialized recycling centers.
3. Product Features
The Gens ace 22.2V 4000mAh 60C 6S LiPo Battery Pack is designed for high-performance applications, offering reliability and efficiency.
- Utilizes superior Japan and Korea Lithium Polymer raw materials for consistent performance.
- Designed for quick recharging and a long cycle life (minimum 150 times).
- Achieves an energy density of up to 200Wh/kg.
- Equipped with an EC5 Plug connector and JST-XHR balancer connector for broad compatibility.
4. Setup
Before initial use, inspect the battery for any visible damage or swelling. Ensure all connectors are clean and free from debris.
- Initial Inspection: Carefully remove the battery from its packaging. Check the battery casing, wires, and connectors for any signs of damage. Do not use if damaged.
- First Charge: For optimal performance and safety, fully charge the battery using a compatible LiPo balance charger before its first use. Refer to the 'Operating: Charging' section for detailed instructions.
- Connecting to Device: Ensure your device (e.g., RC vehicle, drone) is compatible with a 6S (22.2V) LiPo battery and features an EC5 connector. Connect the EC5 plug from the battery to your device's power input. Connect the balance lead to your charger's balance port when charging.

5. Operating
5.1 Charging
Always use a LiPo balance charger. Set the charger to the correct cell count (6S) and capacity (4000mAh). The charging current should generally not exceed 1C (4.0A for this 4000mAh battery) unless the battery specifies a higher charge rate.
- Connect the main EC5 plug to the charger's output port.
- Connect the JST-XHR balance lead to the charger's balance port.
- Select the 'LiPo Balance Charge' program on your charger.
- Set the cell count to 6S and the charging current to 4.0A (1C).
- Start the charging process and monitor the battery and charger throughout. Disconnect immediately if any abnormality is observed.
5.2 Discharging
Avoid over-discharging the battery. Most electronic speed controllers (ESCs) have a low voltage cutoff (LVC) feature. Ensure this is set correctly for 6S LiPo batteries (typically around 3.4V-3.7V per cell, or 20.4V-22.2V total for 6S).
- Stop using the battery as soon as you notice a significant drop in power or when the LVC on your device activates.
- Never discharge below 3.0V per cell (18.0V total for 6S).

5.3 Storage
Proper storage is crucial for battery longevity and safety.
- For short-term storage (a few days), ensure the battery is at a storage voltage of 3.8V-3.85V per cell.
- For long-term storage (more than a week), charge or discharge the battery to a storage voltage of 3.8V-3.85V per cell.
- Store in a cool, dry place, away from direct sunlight, heat sources, and flammable materials. A LiPo-safe bag or container is recommended.
6. Maintenance
Regular maintenance helps ensure the battery's performance and lifespan.
- Regular Inspection: Periodically check the battery for any signs of physical damage, swelling, or unusual odors.
- Connector Care: Keep the EC5 and balance connectors clean and free of corrosion. Ensure they make a secure connection.
- Temperature Management: Avoid operating the battery in extremely hot or cold conditions. Allow the battery to cool down between uses, especially after high-discharge applications.
7. Troubleshooting
If you encounter issues with your Gens ace LiPo battery, consider the following common solutions:
- Battery Not Charging:
- Ensure the charger settings (LiPo mode, cell count, current) are correct.
- Check all connections (main and balance leads) for proper seating.
- Verify the charger is functioning correctly with another battery if possible.
- Reduced Run Time/Power:
- Check if the battery is fully charged and balanced.
- Ensure the low voltage cutoff (LVC) on your device is set appropriately for 6S LiPo.
- The battery may be aging or damaged. Consider replacing if performance significantly degrades.
- Battery Swelling:
- Immediately discontinue use. Swelling indicates internal damage and a potential fire hazard.
- Safely discharge the battery to 0V (if possible and safe to do so, e.g., with a specialized discharger in a fire-safe area) and dispose of it according to local regulations.
