The Ethix lipo bag specifically designed by Mr Steele himself will warm your packs to optimum ripping temps, tell you what voltage they are, charge your gopro and even feel deluxe against your hands with the robust synthetic suede lined interior. 
The internal heating element is designed to run off of a 12V regulator that is built inside. The bag itself is thermally isolated and comes with a sleek zipper to keep all the dirt out, and the high temperature inside. The outer pocket stores your phone while charging, or while you're out and about.
The bag is designed to hold upto 30x 1300mAh 4S or 20x 6S 1300mAh packs neatly.
