You'd think moving to a 9V alkaline would allow you to deliver 9A, but it doesn't really work that way. Unlike LiPo batteries, Alkaline cells have a very high source resistance and their current producing ability -is nowhere near linear. +is nowhere near linear. They work fine to fire commercial low-current +e-matches, but we strongly prefer LiPo batteries for our own projects. If you're using a programmable pyro channel on Altus Metrum products that include that capability (TeleMega, EasyMega, EasyTimer) to do something like
