IMPORTANT PRECAUTIONS FOR CONTROLS AND BATTERY CONNECTIONS HANDLING LITHIUM-POLYMER BATTERIES WARNING!! Never attempt to care for lithium-polymer (Li-Po) cells in the same way as other battery types!! It is very important to have a good understanding of the operating characteristics of Li-Po batteries—especially their exact rated voltage and maximum acceptable charge current. Always read the specifications printed on the label of your Li-Po battery prior to use. Great Planes will not be held responsible for any and all incidental damages and bodily harm that may result from improper use of lithium-polymer batteries with this charger. Failure to follow the care and handling instructions can quickly result in severe, permanent damage to the batteries and its surroundings and even start a FIRE!
