1. Important Safety Information
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. Users must read this safety manual before using the battery.
- Charging: Always use a LiPo-compatible charger. Never charge unattended. Charge in a fire-safe area, away from flammable materials. Do not overcharge or over-discharge. The recommended charge rate is 1C.
- Storage: Store LiPo batteries at a storage voltage (typically 3.8V-3.85V per cell) in a cool, dry place. Do not store in direct sunlight or extreme temperatures.
- Handling: Do not puncture, short-circuit, or disassemble the battery. Avoid physical impact. If the battery swells, leaks, or shows any signs of damage, discontinue use immediately and dispose of it properly.
- Disposal: Dispose of damaged or unusable LiPo batteries according to local regulations. Never dispose of them in regular household waste.
- Children: Keep batteries out of reach of children.

7. Charging Instructions
Proper charging is crucial for the longevity and safety of your LiPo battery.
- Use only a charger specifically designed for Lithium Polymer batteries.
- Always charge in a fire-safe location, such as on concrete or ceramic tiles, away from flammable materials.
- Never leave a charging LiPo battery unattended.
- Ensure the charger settings match the battery's specifications (7.4V, 2S, 5000mAh).
- Always balance charge your LiPo battery. This ensures each cell reaches the same voltage, preventing imbalance and extending battery life.
- Do not exceed the recommended charge rate of 1C (5 Amps for a 5000mAh battery).
- Disconnect the battery from the charger once charging is complete.
8. Maintenance and Storage
Following these maintenance and storage tips will help prolong the life of your HRB Lipo battery:
- Storage Voltage: For long-term storage, charge or discharge the battery to its storage voltage (3.8V-3.85V per cell).
- Temperature: Store batteries in a cool, dry environment, ideally between 5°C and 20°C (41°F and 68°F). Avoid direct sunlight and extreme temperatures.
- Physical Inspection: Regularly inspect the battery for any signs of damage, swelling, or leaks. Discontinue use if any issues are observed.
- Connectors: Keep connectors clean and free from corrosion.
9. Troubleshooting
If you encounter issues with your HRB Lipo battery, consider the following:
- Battery Not Charging: Ensure the charger is properly connected and set for LiPo batteries. Check for damaged wires or connectors. Verify the battery is not over-discharged (below 3.0V per cell), as some chargers may refuse to charge severely discharged batteries.
- Reduced Performance/Run Time: This can indicate an aging battery, improper charging, or an issue with the RC vehicle's power system. Ensure the battery is fully charged and balanced.
- Battery Swelling: Immediately discontinue use and safely dispose of any swollen battery. Swelling indicates internal damage and a significant safety risk.
- Overheating: If the battery overheats during charging or discharge, stop immediately. This could be due to a faulty charger, excessive discharge rate, or internal battery damage.
