3. Safety Instructions
WARNING: Lithium Polymer (LiPo) batteries can be dangerous if not handled correctly. Failure to follow these safety instructions may result in fire, personal injury, or property damage.
- Use only a genuine brand BALANCE CHARGER specifically designed for LiPo batteries.
- NEVER leave the battery unattended while charging.
- Do not overcharge the battery beyond 4.2V per cell.
- Do not over-discharge the battery below 3.2V per cell.
- Always store the battery in a safety guard bag or a fire-resistant container.
- Check the battery condition carefully before using or charging. Discontinue use if the battery shows signs of heating, deformation, leakage, gas venting, or smoking.
- If battery fluid comes into contact with eyes, wash immediately with clean water and consult a doctor.
- Remove the battery from devices when not in use.
- Keep batteries away from children and pets.

4. Setup and Connection
Follow these steps to properly connect your LiPo battery to your RC model:
- Ensure your RC model's power is turned OFF.
- Carefully place the LiPo battery into the designated battery compartment of your RC model.
- Secure the battery to prevent movement during operation.
- Connect the T-plug discharge connector from the battery to the Electronic Speed Controller (ESC) of your RC model. Ensure the polarity is correct.
- Connect the JST-XH balance plug to your balance charger for charging, or to a voltage checker to monitor cell voltage.

5. Charging
Proper charging is essential for the longevity and safety of your LiPo battery:
- Always use a dedicated LiPo balance charger.
- Connect the main discharge plug (T-plug) and the balance plug (JST-XH) to the charger.
- Set the charger to the correct battery type (LiPo), cell count (4S), and charging current. The suggested charge rate is 0.5C-1C (1.65A-3.3A).
- Monitor the charging process and never leave the battery unattended.
- Charging should stop automatically when the battery reaches its full voltage (4.2V per cell).
6. Operation
When operating your RC model with the Youme Power LiPo battery, observe the following guidelines:
- Ensure the battery is securely mounted in your RC model to prevent shifting during maneuvers.
- Monitor the battery voltage during use. Avoid discharging below 3.2V per cell to prevent irreversible damage and maintain battery lifespan.
- If the battery runs out during operation, immediately disconnect it from the Electronic Speed Controller (ESC).
- The battery is designed for high burst discharge, providing steady power for demanding RC applications.
7. Maintenance and Storage
Proper maintenance and storage are crucial for extending the life of your LiPo battery:
- For long-term storage, charge or discharge the battery to its storage voltage, typically around 3.8V per cell. This prevents degradation.
- Store batteries in a cool, dry place, away from direct sunlight, heat sources, and flammable materials.
- Always store LiPo batteries in a fire-resistant LiPo safety bag or container.
- Regularly inspect batteries for any physical damage, swelling, or signs of leakage.

8. Troubleshooting
If you encounter issues with your LiPo battery, consider the following:
- Battery Not Charging: Ensure all connections are secure and your charger settings (LiPo, 4S, current) are correct. Check for any damage to the battery or charger.
- Reduced Run Time: This could indicate an aging battery, improper charging, or over-discharge. Ensure you are not discharging below 3.2V per cell.
- Battery Swelling/Bloating: This is a serious safety concern. Immediately discontinue use, place the battery in a fire-resistant container, and dispose of it properly according to local regulations. Swelling is often caused by over-discharge, overcharge, or improper storage.
- Overheating: If the battery becomes excessively hot during charging or discharge, immediately disconnect it and allow it to cool in a safe, non-flammable area. Overheating can lead to fire.
