Thinking about how to package the battery and electronics in minimum-size, MD 24mm (and 18mm) rockets. There are long, skinny LiPos that could go alongside some of our smallest altimeters, etc. That's nice, because you don't have to assemble a choo-choo train of electronics plus battery (plus electronics plus battery...). Shorter body tubes are lighter and have less skin drag. But with dimensions like 60x11x6mm, for example, if you run the long dimension parallel to the airframe centerline and then accelerate it, what is the g tolerance of such a battery? Would it be better to just wire two or more of the thumbnail-sized 100 mAh cells in parallel and stack them flat, with the largest surface perpendicular to the airframe long axis so the hydraulic head pressure at the bottom of the stack is minimized? Or at least stack them like books side by side, minimizing the height?
