Lithium batteries

In the Harley Davidson's with High compression motors they say to hit the starter for 1 sec then let it set for a few then hit the starter again for 1 sec and let it set a few this gets the battery warmed up and on the third time crank away, I watched one video of a guy cranking a 125 cu in Harley for 2 min and it wasn't slowing down. I know they got power the jigawatt motorcycle battery has 900 cca.
