I have purchased 126 of these, and am trying to think it all out. I believe these are the best, cheapest, largest capacity, lowest weight, and most forgiving of any I have seen. I got mine off Ebay for just over $600. I hope they are the holy grail of batteries for us.Has anyone looked at using these li-ion bags to build a pack? My quick calc is that ~45 pouches would crank up to right voltage range. 8 amp hour rating looks workable. Of course, there is the challenge of a BMS charging system and possibility of explosion and fire inside the small cabin space, but you know... progress requires some sacrifices.
