This is an example of how to use the BatteryLevel function.

//  Display battery voltage for four seconds.
// This version uses floats and requires NXTs with firmware 1.28 or later.

// Note: the BatteryLevel API call returns an unsigned integer giving the 
// battery level in millivolts.
task main()
{
   float volts = BatteryLevel() / 1000.0;
   TextOut(0, LCD_LINE2, FormatNum("Battery: %5.3f", volts), true);
   Wait(SEC_4);
