Safety Warnings
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.
- Read Manual: Users must read the entire safety manual before using the battery.
- Charger Type: You must use a Lithium Polymer (LiPo) specific balance charger only. Do not use NiMH, NiCd, or other battery chargers.
- Charge Rate: The suggested charge rate is 0.5 - 1C. Exceeding this rate can damage the battery and pose a fire risk.
- Unattended Charging: Never charge the battery unattended. Always monitor the charging process.
- Temperature: Do not charge or discharge batteries in extreme temperatures. Keep batteries away from direct sunlight, heat sources, and flammable materials.
- Physical Damage: Do not puncture, drop, short-circuit, or disassemble the battery. If the battery is damaged, swollen, or leaking, discontinue use immediately and dispose of it safely.
- Storage: Store batteries in a fireproof container or bag, away from children and pets, at room temperature and at a storage charge (typically 3.8V per cell).
- Disposal: Dispose of damaged or depleted LiPo batteries according to local regulations. Never throw them in household trash.

Setup
Before first use, ensure your battery is properly prepared.
- Unboxing and Inspection: Carefully remove the batteries from the packaging. Inspect them for any signs of physical damage, swelling, or leaks. Do not use if any damage is observed.
- Initial Charge: For optimal performance and safety, it is recommended to fully charge the battery before its first use. Use a compatible LiPo balance charger and set the charge rate to 0.5-1C (e.g., for a 6000mAh battery, charge at 3.0A to 6.0A).
- Connector Check: Ensure the EC5 connector on the battery is clean and free from debris. The JST-XH balance connector should also be checked for proper pin alignment.
- Compatibility: Verify that your RC vehicle's ESC (Electronic Speed Controller) and motor are compatible with 3S (11.1V) LiPo batteries and the EC5 connector type.

Operating
Using your Zeee Lipo battery in your RC vehicle.
- Installation: Securely install the battery in your RC vehicle's battery compartment. Ensure it is snug and cannot shift during operation.
- Connection: Connect the EC5 connector from the battery to the corresponding connector on your RC vehicle's ESC. Then, if applicable, connect the balance lead to your vehicle's balance port or a separate monitoring device.
- Compatible Vehicles: This battery is specially compatible with 1/8 and 1/10 scale RC cars, Losi, Slash, HPI Strada XB 1/10 RTR Electric Buggy, Team Associated, Axial, Duratrax, Emaxx, Bandit, and Rustler versions. Always ensure the voltage, dimensions, and plug type match your specific model.
- Monitoring: During operation, avoid over-discharging the battery. Most ESCs have a low-voltage cutoff (LVC) feature for LiPo batteries. Ensure this is set correctly to prevent damage.
- Disconnection: After use, always disconnect the battery from the vehicle.

Maintenance
Proper maintenance is crucial for the longevity and safety of your LiPo battery.
- Storage Charge: For long-term storage, charge or discharge the battery to its storage voltage (typically 3.8V per cell). Do not store fully charged or fully discharged.
- Storage Environment: Store batteries in a cool, dry place, away from direct sunlight, heat, and moisture. A fireproof LiPo bag or container is highly recommended.
- Regular Inspection: Periodically inspect your batteries for any signs of swelling, damage to the casing, wires, or connectors. Discontinue use if any issues are found.
- Avoid Over-Discharge: Never discharge the battery below 3.2V per cell. Over-discharging can permanently damage the battery.
- Balance Charging: Always use the balance charging function of your LiPo charger to ensure all cells are charged equally, which helps maintain battery health.

Troubleshooting
Common issues and potential solutions for your Zeee Lipo battery.
- Battery Not Charging:
- Ensure the charger is properly connected and powered.
- Check all battery connectors (EC5 and JST-XH) for secure connection and damage.
- Verify charger settings are correct for a 3S LiPo battery.
- If the battery is severely over-discharged, some chargers may refuse to charge it for safety reasons.
- Reduced Run Time:
- Battery may be aging; LiPo batteries have a finite number of charge cycles.
- Ensure the battery is fully charged and balanced before use.
- Check for excessive current draw from your RC vehicle (e.g., motor issues, binding drivetrain).
- Environmental factors like cold weather can temporarily reduce capacity.
- Battery Swelling:
- IMMEDIATELY DISCONTINUE USE. Swelling indicates internal damage, often due to overcharging, over-discharging, or physical abuse.
- Move the swollen battery to a safe, non-flammable location (e.g., outside in a fireproof container).
- Do not attempt to charge or use a swollen battery. Dispose of it safely according to local regulations.
- Overheating During Use:
- This can be a sign of excessive current draw from your RC vehicle or an internal battery issue.
- Check your vehicle's motor, ESC, and gearing for proper setup and efficiency.
- If the battery consistently overheats, discontinue use and inspect for damage.
