Doesnt anyone move up to 18volt from 12?

so far my dynatron has been fine with engines up to zenoah 45's....but starts to slow down!

the dynatron will handle 2x12 volt batteries in series giving 24volt - and more volts means more torque..!
its easy to use two 12's as their both the same capacity.
I have tried one 12v in series with one 6v - both of the same capacity (ie amps per hour)
this gives me a faster spin with 18volts - and both batteries give up eventually - at the same time (because everybodies borowing it at the field!!)

but like Betelgeuze said - be carefull with all that torque that your engine isnt locked up!!

regards 2 all
