Glow Plug Igniter run off RC LiPo battery bump starter box with voltage regulator

I wanted less things to carry when taking my RC cars car out. I wanted to run the glow plug igniter off the liPo batteres that power the bump box. You need a igniter with a voltage regulator. The glow plug is expecting 1.2V. If you supply the voltage coming straight from the battery its going to burn out the glow plug coil. The voltage regulator is sometimes referred to a buck converter
