WARNING: Lithium Polymer (Li-Po) batteries come partially charged and are significantly more volatile than the alkaline, Ni-Cd or NiMH batteries used in RC applications. Keep batteries out of reach of children, unless supervised by a responsible adult. All interactions and warnings found on the sheet inside of this cad must be followed exactly. Mishandling of Li-Po batteries can result in a fire.

Before handling and first use, visually and physically inspect the battery pack, wire leads, and connectors to ensure there are no loose connections which may cause short circuit and eventual fire. By handling, charging or using this Li-Po battery you assume all risks associated with Li-Po batteries.
