I wonder where some of this info comes from
The 1100 and 2300 ma cells sold by DeWalt/Black n Decker (VPX) are same chemistry
use the same charger on either
As for low power input ignitions
Look at the logic when deciding how much battery power you need..
It takes MORE power to fire thru higher pressure in the combustion chamber.
These little engines typically have quite low cyl pressures so if the low output setups work, you are working with a low output engine. No secret there
if it will run on 80 oct fuel it is a low output engine. I don't care what power is claimed .
When testing for performance , test using a high output ignition too.
Just because the engine is not sputtering does not mean the spark is adequate.
High output ignitions do add performance in high output engines . some of these rehashed weed eaters are not high output so any spark will run em.
