Safety Warnings
Lithium Polymer (LiPo) batteries require careful handling. Failure to follow these safety guidelines can result in fire, personal injury, or property damage.
- Users must read the safety manual before using the battery.
- Use only a Lithium Polymer (LiPo) specific balance charger.
- The suggested charge rate is 0.5 - 1C. Do not exceed 5C fast charge capability.
- Never charge the battery unattended.
- Maintain ambient charging temperature between 41°F (5°C) and 95°F (35°C).
- Do not puncture, disassemble, short circuit, or expose the battery to extreme temperatures or direct sunlight.
- If the battery swells, leaks, or shows any signs of damage, discontinue use immediately and dispose of it properly.

Application Compatibility:
This Zeee 3S 5200mAh Lipo battery is compatible with various RC models, including helicopters, airplanes, multirotors, boats, cars, and trucks. It is suitable for 1/10 scale vehicles or larger, such as Traxxas Slash VXL, Slash 4x4 VXL, E-Maxx Brushless, E-Revo Brushless, and Spartan models. Compatibility is ensured if the voltage, dimensions, and plug type match your specific RC model requirements.

Setup and Charging
Choosing a Charger:
- The charger must have a balance charging function.
- The charger must support 3S battery charging (11.1V nominal, 12.6V fully charged).
- The recommended charging current for this battery is 2.6A to 5.2A. Ensure your charger supports this range.
Charging Process:
- Connect the battery's main discharge plug (T Plug or XT60) to the charger's output.
- Connect the battery's balance lead to the charger's balance port.
- Select the LiPo balance charge program on your charger.
- Set the correct cell count (3S) and charging current (0.5-1C, e.g., 2.6A to 5.2A for a 5200mAh battery).
- Start the charging process and monitor the battery throughout. Never leave charging batteries unattended.

Operating Instructions
- Ensure the battery is fully charged and balanced before use.
- Securely install the battery in your RC model, ensuring it does not shift during operation.
- Connect the battery's discharge plug to your RC model's ESC (Electronic Speed Controller).
- Always monitor battery temperature during operation. If the battery becomes excessively hot, stop use immediately and allow it to cool.
- Avoid over-discharging the battery. Most ESCs have a Low Voltage Cutoff (LVC) feature; ensure it is set correctly for 3S LiPo batteries.
- After use, allow the battery to cool down before recharging or storing.
Maintenance and Storage
- Storage Voltage: For long-term storage, charge or discharge the battery to its storage voltage (typically 3.8V per cell).
- Storage Environment: Store batteries in a cool, dry place, away from direct sunlight, heat sources, and flammable materials. A LiPo-safe bag or container is recommended.
- Regular Inspection: Periodically inspect the battery for any signs of damage, swelling, or leaks. Do not use damaged batteries.
- Disposal: Dispose of damaged or old LiPo batteries responsibly at designated battery recycling centers. Never throw them in household trash.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Incorrect charger settings, faulty charger/battery, poor connection. | Verify charger settings (3S, LiPo mode, current). Check all connections. Try a different charger if available. |
| Battery swells or gets hot during charge/discharge | Overcharging, over-discharging, internal damage, excessive current draw. | Immediately disconnect the battery. Do not use. Dispose of safely. Ensure correct charger settings and appropriate LVC in your RC model. |
| Short run time | Battery degradation, high current draw from model, improper charging. | Ensure battery is fully balanced. Check for excessive load on your RC model. Consider battery age and cycle count. |
| Uneven cell voltage | Improper balance charging, damaged cell. | Always use a balance charger. If cells remain unbalanced after multiple balance charges, the battery may be damaged and should be replaced. |
