I'm making my own little accelerometer based delay timer board ("little" being the operative word) to make a 24mm 2-stage composite motor rocket. Weight is at a premium in my design, so I'm trying to use as small of a battery as possible. If necessary, I can probably get away with a very small ( 2-cell?) lipo battery. However, the idea I'm considering right now is a coin battery connected to a pump-up DC-DC converter connected to a capacitor. Thus I could take a 1V low-current battery and turn it into a 12V high-current discharge. The question is, how big of a capacitor would I need?
Anyone have any guidance on this? (Or do I need to go buy a bunch of igniters and do my own tests?)
As an fallback, anyone know if a single cell (3.7V) lipo battery will ignite an igniter, or do I need to go to a 2-cell 7.4V lipo?
