Heated Jacket Power Bank 7.4v 4400mAh (AC403)

AC403PC-7V4400 battery is 7.4v 4400mah version of AC403 rechargeable li ion battery pack. AC403 battery is 4x18650 li ion rechargeable battery pack designed for heated jacket and other heated products with PWM the adjustable pulse DC output technology. 

Application products like: heated jacket, milwaukee heated jacket, heated gloves, dewalt heated jacket, heater body suit and other heated wears products. The AC403 battery is designed for electric heated wears application.  It's size is  24*81*95mm( 24*81*100mm for wireless version) , with an ON/OFF switch and a LED screen, a 3.5*1.35mm coax type socket connector. 

The AC403 battery LED screen can be made to reflect the battery fuel level status by displaying number 0~9, 9=full, 0=need charge.
The AC403 battery can be made to have different output mode: Constant DC type, Pulse DC type (adjustable pulse settings), or two both.  Asarke Heated Clothing Battery is using Pulse-Width Modulation(PWM) or Pulse-Duration Modulation (PDM) technology which able to control/adjust the output power rate thus achieve desirable heat level in heater. 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.
The AC403 battery has backwards DC port with aperture to hold the plug which make perfect stable connection, specially good for heated sports wears application. 
By adopting different cells the capacity can be:
14.8V 2200mah/2600mah/3200mah/3400mah
7.4V 4400mah/5200mah/6400mah/6800mah
3.7v  8800mah/10400mah/12800mah/13600mah
*For 11v battery we have smaller size version AC301 in same function by 3x18650 design.
