• Designed for one to three cell Lithium
        batteries with Lightning Power  type balancing plug
• Match up the positive to positive and negative to
        negative terminals.  In the event that positive and negative
        wires are mixed up, the Lightening Power Onboard Battery
        Monitor will not light up.  No damage to the unit or battery
        will occur; just reverse the connection.
• Each cell is at or above 3.3 volts when the corresponding light
        is green ( i.e. 3s lithium polymer pack @ 10volts equal three solid
        green lights on the monitor)
• Whenever any cell drops below 3.3volts, a red light will light up
        solid (the battery monitor will work only if the batter is under load;
        i.e. hovering the helicopter).
• The kit includes the following:
                                              1.  Battery monitor
                                              2.  Two 4.5 ” wire extensions (Thunder Power/ 
                                                   Flight Power and Lighting Power compatible)
                                              3.  Double sided foam tape.
