You can do it with a single battery. All that's needed is for the long wire to carry enough current to drive the relay coil. Battery goes by the pad.
Connect from +12V to a NO contact of the relay. Connect the other contact through the igniter to -12V. Run a wire from +12V to your launch button then back to the to the top of the relay coil. Connect the other end of the coil to -12V. I made the switch removable for a safety. Keep switch with you. Plug in and it's ready to fire.
This is what I used for the 1000' controller for this static test.
