Haven't used the pack at the moment, but find that the quality of components is excellent.
l have been using the Single cylinder start pack and I found that using a two cell Lipo. did not give a positive spin up and the motor and esc got a bit warm.
Switching to an eight cell Nimh battery gave an almost instant start with no apparent heating by touch felt
Using my Mega Meter I got these test figures.
Standing current 0.40A
Possibly glow plug current?
Maximum start current 21.22A
Maximum start wattage 193.5W
