Launch Controller Batteries

Is there a reference somewhere listing how much battery power is required for an igniter to start a rocket motor?

The reason being that I wish to construct my own launcher and want it to have adequate power, but not vaporize the rocket when I push the button. LOL

I plan on using it to ignite mini-motors through D sized motors. I know Estes has used 4x "AA" baterries, 4x "C" batteries, and 12v lantern batteries in the past.

Maybe even using a rechargeable USB style battery, if it can safely be utilized.
I'd also like to consider using a heavier gauge and longer length wire and more robust micro-clips. I am looking for suggestions and examples. Also maybe advice on cluster ignition too.

Thanks!

Per the back of a newer package of Estes igniters they require 6 to 12 volts. The minimum all fire current is 2 amps and the maximum no fire current is 500 mA (0.5 amp).

I use a 20v rechargeable Li-Ion drill battery. Small, fits in my controller, easy to come by and I already have them for my cordless power tools. I use a 4 ohm 100 watt current limiting resistor paired with the loss in 25 to 30 foot extension cord put the right amount of current to instantly ignite without drawing excess. If my memory serves me (bad idea) I'm drawing about 4 amps. Like many of us I'm an engineer (electrical), so I like to over do this type of stuff. Laugh if you want but it works fantastic and I want the motor to ignite when the fire button is pushed NOT have to hold it for 15 seconds. We Launch all day and still have plenty of juice to keep going. Absolutely zero misfires regardless if using the old pyro tip or new style Estes igniters.

you Really want to have something that can handle 12 volts, this will let you move up to cluster motors.

For cluster ignition, I would suggest that you look into a relay launch system. That way the battery is next to the launch pad, and the remote only throws the relay, so it can be low current wires. All of the high current wires are shorter and next to the pad.
