insert witty tagline here
I'm dreaming up a new scratch build and I could use some guidance from those of you here on TRF that really know batteries.
Here's the situation - I might need to airstart as many as nine black powder motors at once. I would be using Q2G2 igniters. Avionics are still being considered but I have available either: a Perfectflite MiniTimer (which I've used on a few rockets already to airstart up to three motors at once), a MissileWorks RRC3, or a Featherweight Raven. I've been reading up on using dual 9v's (wired per specs from the altimeter manufacturers in question) and know that that is one possible option. And I've been reading quite a few threads that get into technical detail on battery outputs, voltage drops, amperage ratings, and such, and quite honestly I get most of it, but after a while my head starts to spin a bit.
So....those of you who DO really get it - what would you recommend? Which avionics/battery setup would you choose/recommend if you wanted to airstart 9 BP motors? Simple timer, or auxillary output from a full featured altimeter? Dual 9v's, or some specific LiPo? Do I even need more oomph than I could get from a plain old (but fresh) 9v? (and yes, "oomph" is plenty enough technical jargon for me).
thanks in advance, s6
