Charging the Battery
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.
Your UMX Extra 300 3D comes with a 1S 3.7V Li-Po Battery
Charger and 150mAh 1-Cell 3.7V 12C Li-Po battery. It is
important that you only charge with the included charger,
or the E-flite
®
Celectra™ 4-port Charger (EFLC1004). Refer
to battery warnings. We recommend you charge the battery
pack first. You will need the flight battery 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. Remove the cover on the bottom of the charger and install four of the included AA batteries, noting
proper polarity. Replace the cover after the AA batteries are installed.
3. Slide the battery into the slot on the charger. The end cap of the battery is specifically designed to
allow the battery to fit into the slot one way (usually with the label on the battery facing outward)
to prevent reverse polarity connection. However, check for proper alignment and polarity before
proceeding to the next step.
4. Gently press the battery and its connector into the charge jack/connector located at the bottom of
the slot in the charger.
5. When you make the connection successfully, the LED on the charger turns solid red, indicating
charging has begun.
6. Charging a fully discharged (not over-discharged) 150mAh battery takes approximately 25–30
minutes. As the battery nears full charge, the LED begins to blink.
7. When the battery is fully charged, the LED blinks approximately every 20 seconds or goes out en-
tirely.
Note
: If the LED stays on when the Li-Po is removed, the AA batteries in the charger are low.
8. Always unplug the battery from the charger immediately upon completion of charging.
CAUTION
: Overcharging a battery can cause a fire.
