8 AA's should be fine for receiver & single igniter. Thumbnail is for single or multiple paralled igniters. IRF540N was suggested by wayneh & looks like a good choice as it allows 22A of firing current & probably up to 80A in this use. Suggest C or D cell batteries for firing ckt. Some C & D cells are AAs wraped up in C & D clothing.
