Lithium Polymer batteries don't perform well when cold, as many pilots from up north have probably experienced! For maximum discharge capability, LiPo batteries should be slightly warm, and this heated lipo storage case does just that. Check out all our chargers & charging accessories and all of our TBS Products! Features 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 action camera, 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 maintain 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 up to 30x 1300mAh 4S or 20x 6S 1300mAh packs neatly.
