Abstract
An intrinsically safe battery pack assembly (200) is formed by disposing electrical components (208) on a single side of a printed circuit board (PCB) (210) and coating the component side of the PCB with a low pressure molded encapsulation (220). The bottom surface of the PCB provides interface contacts for a charger and radio. The LPM encapsulation is formed over the top side of the PCB to cover the electrical components at a predetermined height set to be at the height of the tallest component. The top surface of the PCB having the electrical components and LPM encapsulation (220) is oriented to face the plurality of battery cells within the battery pack (200).
