Step 16: Batteries

Picture of Batteries
For everything that needs a AA battery, like the Canon camera and the Microtrak, you'll want to get yourself at least 12 AA lithium batteries. They usually comes in a blue package. Let me remind you, these are lithium and not lithium-ion.

Lithium batteries work in extreme cold condition, which you will be facing in near space.
