Since the last update on the Sx350 chip they have been recommending that you run dual batteries. I have never ran dual batteries before except in my vamo. This is my first box mod that I will be using with dual batteries. How is the best way to wire up the the chip? I am getting the keystone 18650 battery holder and putting it into the Hammond 1590g box. I will post pictures when I am fully done with the box but really need help with the wiring for the batteries. Thanks ahead of time.
