Hey guys, we’re looking at sending one of your mintyboost kits to space. Well, 100,000 anyway. We’re going to launch a weather balloon with some electronics aboard. We’re considering using the mintyboost to ensure the batteries don’t run out before recovery. But weight’s an issue. Can you tell me what the weight of the mintyboost is?

I assume he was referring to 100,000 feet. Not 100,000 units!
The weight can be reduced by shaving down the plastic of the battery holder and by shortening the leads. Every fractional gram of overhead saved leaves more for payload.
Also you can get rid of the Usb plug, and socket, just solder the cable directly
Awesome! Congrats Adafruit!
And lets not forget shaving the smallest corners of unused PCB, eliminating the 8 pin socket, and weighing the batteries to find the lightest ones. (keeping in mind mA ratings – dry cells are nice, but..)
Use (1) LiFePO4 cell and solder the battery wires directly to it. Forget the batt holder all together.. Lithium Iron Phosphate is light weight.
