Hay Micro,
Maybe you need to work out more.
I have a heavy duty starter that won't turn my HC Saito .80 when powered by a 7 AH 12V battery. Spins it fine when it's run by a 12V lawn tractor battery. Hint: it ain't the volts, it's the amps.

Hey, better check your theory with a wattmeter, the 7AH 12 gel cells like the one i have in my flight box won't hold the voltage when placed under the heavy load of a starter, this is why your lawn tractor battery will spin it and it will probably stay at 12V, and your hint is not a hint becuase when you put more volts to a DC electric motor it will also increase the amperage which means more power.
That's what I was telling you, in a nutshell. You can have all the starter in the world AND you can toss in another 6 volt battery -your reference to 18 volts - but if the combination of batteries can't supply the necessary current (power) you won't spin the engine. Get it now?
