Conventional 12V battery cars for cars and motorcycles can be directlymodified for power supply; 24V battery cars such as large trucks are notrecommended, because the voltage will exceed 24V after the car isstarted. Unless the voltage is reduced by other equipment, the poweramplifier will heat up too much and will be used for a long time. It is notgood for the chip and even burns out. Features:
