Charging the Battery

Your Beast comes with a Celectra™ 1-Port 2S 7.4V
DC Li-Po Charger and UMX 2-Cell 7.4V 120 mAh
20C Li-Po battery. Please visit www.horizonhobby.
com for optional battery adapters. Refer to battery
warnings. It is recommended to charge the battery
pack while you are inspecting the aircraft. The flight
battery will be required to confirm proper aircraft
operation in future steps.

The Battery Charging Process

1. Charge only batteries that are cool to the touch and are not damaged. Look at the battery to make
sure it is not damaged e.g., swollen, bent, broken or punctured.
2. The connector on the battery is specifically designed to allow the battery to fit into the charge port one
way to prevent reverse polarity connection. However, check for proper alignment and polarity before
proceeding to the next step.
3. Gently press the battery connector into the charge port located on the front of the charger.
4. When you make the connection successfully, the green LED blinking on the charger slows, indicating
proper connection.
5. Press the button on the charger, the red LED will illuminate, indicating charging has begun.
6. Charging a fully discharged (not over-discharged) 120mAh battery takes approximately 25–30
minutes.
7. When battery is fully charged, the green LED will illuminate.
8. Always unplug the battery from the charger immediately upon completion of charging.
CAUTION: Overcharging a battery can cause a fire.
WARNING: Failure to use the proper charger for a Li-Po battery can result in serious damage, and if left
charging long enough, will cause a fire. ALWAYS use caution when charging Li-Po batteries.
WARNING: Selecting a charge rate higher than 2.5 times the battery capacity may cause a fire.
