Plug the USB charger into a device, computer, or other suitable power source. Carefully
plug the battery connector into the charge plug. Note the orientation of the battery plug
to the receptacle, it will only plug together one way so be gentle and don’t force it!
You’ll notice that the red LED is illuminated once the battery pack is properly connected
to the charge lead. When the LED is lit, the battery is charging. Once it goes out, the
battery is charged and ready for use. Depending on the device (computer, phone charger,
etc.) charging times will vary from 20-40 minutes.
IMPORTANT NOTES ABOUT LITHIUM-POLYMER BATTERIES
• Space-Age Lithium Polymer (Li-Po) batteries are amazing in their ability to store energy. However,
they must be treated with care. Even the tiny battery in this helicopter has the energy potential to
cause an explosion or fire if mishandled or abused, so please treat it accordingly.
• Misuse or abuse of LiPo batteries can cause personal injury, property damage, and bodily harm.
Purchaser assumes all risk in use of this product. If purchaser is unable or unwilling to assume such
