2. Safety Information
Lithium Polymer (LiPo) batteries are powerful and require careful handling. Failure to follow safety instructions can result in fire, personal injury, and property damage. Always observe the following precautions:
- Charging: Use only a compatible LiPo balance charger. Never charge unattended. Do not overcharge or discharge beyond recommended limits.
- Temperature: Do not expose to extreme temperatures (above 60°C / 140°F or below 0°C / 32°F). Avoid direct sunlight.
- Physical Damage: Do not puncture, drop, short-circuit, or disassemble the battery. Discontinue use if the battery is damaged or swollen.
- Storage: Store in a fireproof container or bag, away from flammable materials, and out of reach of children.
- Disposal: Dispose of LiPo batteries according to local regulations. Never dispose of in regular trash.
3. Setup
3.1 Unpacking and Inspection
Upon receiving your TATTU Pro battery, carefully inspect it for any signs of damage during transit. Check the casing, connectors, and cables. If any damage is observed, do not use the battery and contact customer support immediately.
3.2 Initial Charge
For optimal performance and longevity, it is recommended to fully charge the battery before its first use. Use a compatible 12S LiPo balance charger with an AS150U-F connector. Ensure the charger settings match the battery's specifications (44.4V, 12S, 22000mAh).

3.3 Connecting to Device
Connect the AS150U-F discharge plug of the battery to your compatible device (e.g., drone, RC vehicle). Ensure a secure connection. The smart battery features allow for communication with compatible devices to monitor battery status.
4. Operating Instructions
4.1 Charging the Battery
Always use a dedicated LiPo balance charger. Connect the main AS150U-F plug and the balance lead to the charger. Set the charger to the correct cell count (12S) and voltage (44.4V). The charging current should not exceed 1C (22A for this 22000mAh battery) unless specified otherwise by the manufacturer. Monitor the charging process and never leave a charging battery unattended.
4.2 Discharging and Usage
The TATTU Pro battery is designed for a 25C continuous discharge rate, with a maximum burst rate of 50C. Ensure your application's current draw is within these limits. Monitor the battery voltage during use. Do not discharge the battery below 3.7V per cell (44.4V total for 12S) under load, or 3.0V per cell (36V total for 12S) at rest, to prevent irreversible damage.
The integrated smart features provide real-time data such as fuel gauge, current detection, and usage logs, which can be accessed via compatible smart battery systems.
5. Maintenance and Storage
5.1 Proper Storage
For long-term storage, charge the battery to a storage voltage of 3.8V-3.9V per cell (approximately 45.6V-46.8V for 12S). Store the battery in a cool, dry place (ideally between 5°C and 20°C / 41°F and 68°F) away from direct sunlight, heat sources, and flammable materials. Use a LiPo-safe bag or container.
5.2 General Care
Regularly inspect the battery for any signs of swelling, damage, or loose connections. Keep the connectors clean and free from debris. Avoid dropping or subjecting the battery to heavy impacts. If the battery becomes wet, dry it thoroughly before attempting to use or charge it.

6. Troubleshooting
- Battery Not Charging: Ensure the charger is properly connected and functioning. Verify charger settings match battery specifications. Check for any visible damage to the battery or connectors.
- Reduced Performance/Short Run Time: This could indicate an aging battery, improper charging, or over-discharge. Ensure proper charging and storage practices.
- Battery Swelling: Immediately discontinue use and safely dispose of the battery. Swelling indicates internal damage and a significant safety risk.
- Smart Features Not Responding: Ensure the battery is properly connected to a compatible device or smart charger. Refer to your device's manual for troubleshooting smart battery communication.
If you encounter issues not covered here, or if troubleshooting steps do not resolve the problem, please contact TATTU customer support.
