Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction, pulsating direct current is used on PWM controllers. By PWM control technology, a 15v battery can have output equal with 3.7v/7v/11v battery to generate equivalent heat level. The PWM control technology enable the battery output adjustable to any heating levels in request, it could be 3 settings, 4 settings or up to 9 settings. 

The AC402 battery is perfect for 7V/12V/15V heated clothing.
