Best battery for starting RCMK R254 EVO engine

MrUnlimited · May 24, 2012

Guys,

What do you suggest as battery for powering my Sullivan Tork startermotor to start my 26cc RCMK R254 EVO engine? I blown today a 5s 35C 5000mah battery when trying to start the enigne. What is the best battery? The old fashioned 12V car battery of something lighter to carry.

I use a 19.2 volt lithium-ion Die Hard from Sears with a Sullivan S-650 starter. The two together turn my highly modified, very high compression, rear exhaust QD 4,000+ RPM for starting. I also have a precision machined 2.000" dia. brass flywheel that accepts a Gates Truflex 2L210 "V" belt. The fully charged battery can turn the engine over for starting about 50 times. There is a light on the battery to indicate when the battery needs charging.

The battery, starter, belt, & flywheel are 100% reliable.

Thanks Jim, I also was looking for A 123 systems batteries. 6 batteries gives 19.8v with 2300mah and a max draw power of 120amps.

That should be plenty. The S-650 will give 600 in-oz of torque while drawing 100 amps.
