AirTek LIPO User manual

Thank you for purchasing your Lipo pack from Airtek Hobbies. Lipo batteries outperform previous battery technology such as
Ni-Cd and Ni-MH by a signicant margin in terms of capacity, voltage and weight. The downside to these performance gains
are that lipo batteries require special handling and care. When following these guidelines you can expect safe and reliable
performance from your battery pack.
PLEASE THOROUGHLY READ THE FOLLOWING INSTRUCTIONS BEFORE USING YOUR BATTERY PACK FOR THE FIRST TIME.

This considerably reduces the charging times which for many modellers provides greater convenience and ying time.
