great reply guys. This should help a lot of people that just do not know...i am one of them.
I HAVE BEEN FLYING GAS AIRPLANES SINCE 1946...TOO OLD TO CARE ABOUT DOING THE MATH.
JUST STARTED USING A-123 LIFE BATTERIES...MY IGNITION SYSTEMS ARE ALL GOOD FOR AT LEAST 7 VOLTS. HOWEVER, IT WAS NOT THAT WAY IN THE PAST.
GOOD JOB TO TRUCKRACER AND PULL UP FAST.
