Please read these instructions carefully before use to ensure optimal performance and safety.
2. Safety Guidelines
Lithium Polymer (LiPo) batteries are powerful and require careful handling. Failure to follow these safety guidelines can result in fire, personal injury, and property damage.
- Charging: Always use a LiPo-compatible charger. Never charge unattended. Charge in a fire-safe area, away from flammable materials. Do not charge a swollen, damaged, or punctured battery.
- Storage: Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures. Use a LiPo-safe bag or container for storage. Do not store fully charged or fully discharged for extended periods.
- Disposal: Dispose of damaged or unusable batteries safely according to local regulations. Never throw LiPo batteries in regular trash.
- Handling: Do not short-circuit the battery terminals. Avoid physical damage, such as dropping or crushing. Keep out of reach of children and pets.
- Temperature: Do not expose to temperatures above 60°C (140°F). Do not use if the battery is excessively hot.

4. Setup
Before connecting the battery to your RC model, ensure all components are compatible and correctly configured.
- Inspect Battery: Visually inspect the battery for any signs of damage (swelling, punctures, loose wires) before each use. Do not use a damaged battery.
- Connectors: Ensure the XT60 plug on the battery matches the connector on your RC model. If an adapter is needed, ensure it is of high quality and rated for the battery's current.
- Secure Placement: Securely mount the battery in your RC model using straps or a battery tray to prevent movement during operation. Ensure wires are not pinched or exposed.
- Balance Lead: The JST-XH balance lead is used for charging and monitoring individual cell voltages. Ensure it is connected to your charger's balance port during charging.

5. Charging Instructions
Proper charging is critical for the longevity and safety of your LiPo battery.
- Use a LiPo Charger: Only use a charger specifically designed for Lithium Polymer batteries with a balance charging function.
- Connect Battery: Connect the main XT60 plug of the battery to the charger's output port. Then, connect the JST-XH balance lead to the charger's balance port.
- Set Parameters: Set the charger to the correct battery type (LiPo), cell count (3S), and charging current. A charge rate of 0.5-1C is suggested for optimal battery health, though the battery is capable of 5C fast charging. For this 1500mAh battery, 1C is 1.5A.
- Monitor Charging: Stay present and monitor the battery during the entire charging process. Disconnect immediately if you observe any swelling, smoke, or excessive heat.
- Full Charge: The charger will indicate when the battery is fully charged. Disconnect the battery from the charger once charging is complete.

6. Operating Instructions
Follow these guidelines for safe and effective operation of your RC model with the Zeee LiPo battery.
- Initial Check: Before each use, ensure the battery is fully charged and securely installed in your RC model. Check all connections for tightness.
- Discharge Limits: Do not discharge the battery below 3.0V per cell (9.0V for a 3S battery). Over-discharging can permanently damage the battery. Most ESCs (Electronic Speed Controllers) have a low voltage cutoff feature; ensure it is set correctly for LiPo batteries.
- Temperature Monitoring: If the battery becomes excessively hot during use, stop operation immediately and allow it to cool down before further use or charging.
- Avoid Overload: Do not continuously draw current beyond the battery's specified discharge rate (120C).
7. Maintenance and Storage
Proper maintenance and storage will extend the lifespan of your Zeee LiPo battery.
- Storage Voltage: For long-term storage, charge or discharge the battery to its storage voltage (typically 3.8V-3.85V per cell).
- Cool, Dry Place: Store batteries in a cool, dry environment, ideally between 5°C and 20°C (41°F and 68°F).
- LiPo Safe Bag: Always store LiPo batteries in a fire-resistant LiPo safe bag or container to minimize risk.
- Regular Inspection: Periodically inspect stored batteries for any signs of swelling or damage.

8. Troubleshooting
Here are some common issues and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Damaged balance lead/main connector, faulty charger, over-discharged battery. | Check connections, try a different charger, or consult Zeee support if the battery is severely over-discharged. |
| Battery swells during charge/discharge | Overcharging, over-discharging, physical damage, internal cell damage. | Immediately disconnect and safely dispose of the battery. Do not use. |
| Short runtime | Battery degradation, improper charging, high current draw from model. | Ensure full balance charge, check model's power consumption, consider battery replacement if old. |
