    A number of the posts above mention LiPo batteries. Please think twice before doings so. LiPo cells can be damaged, especially on landing should something go wrong (like your parachute get tangled). As many of you know, LiPo cells can easily start a lithium fire when damaged and unlike most uses, you are not usually close enough to deal with any problems. Depending on the weather and location, it can be hours, days, or you may never actually locate the payload.
    The Energizer L91 Batteries used here are safe and work well with the cold. If you need rechargeable, standard Li-Ion metal cells will be a better than the plastic LiPo cells, but the by far the best bet is using LiFePO4 cells that are much safer to use.
