• It takes approximately 30–40 minutes to charge a fully dis-
charged (not over-discharged) battery. As the battery nears
full charge, the LED light will begin to blink. When
the battery is fully charged, the LED light will blink
approximately every 20 seconds or will go out entirely.
Note: The Li-Po battery included with your J-3 Cub will arrive
partially charged. For this reason the initial charge may
only take 15–20 minutes.
Note: You can expect to charge the Li-Po flight battery
approximately 15–20 times before it will be necessary
to replace the AA batteries in the charger. Replacing
the included batteries with alkaline batteries will result
in more charge cycles than with the included batteries.
Note: If LED remains on for longer than 40 minutes
while charging and/or 5 seconds after removing the
Li-Po flight battery, please replace the AA batteries in
the charger.
