    I need to find what will be a simple answer for all of you guys, I teach and fly radio control aircraft so when things are working I just switch on and that's it. but we use batteries to run stuff. my question is, what resister do I need to use to make a 2volt battery run a 1.5v glow plug? this is in a glow engine. we use pre-made circuit boards to run starter motors and glow plug. but I do have loads of these batteries so if I could make a load of these battery connecters all the guys a teach could have a cheep glow plug starter, thanks for this guys

    You would probably need a simple voltage regulator to have best performance. Any idea what current a glow plug draws?

    Something like this...

    though you may want to add a few capacitors for stability.
