For work a Vision 1300 mAh with a T3 attached and 2 evods in my pocket for back ups plus a ego c 1000 mAh twist in my clipboard and an extra Kgo 650 mAh that stays in my truck. At home, I use either my Vamo or Tesla or both with any one of the following attached to it. J tank, DCT tank, Iclear 30 or my HH357 when I feel like dripping.
