Apples to apples test today. Greenworks battery drilled 82 holes through 24″ of ice. Strikrmaster battery drilled 78 holes… Both batteries were in the back of my truck since last night. Both batteries were the 6.0. I did not buy a Chinese greenworks battery though, it was $147. Strikrmaster 6.0 is around $215. Label on the strikrmaster battery says 216 watt hours. Label on greenworks battery says 240 watt hours. Pulled both battery packs out of the case and both sets of batteries are identical down to the numbers.

I just ordered a new 6 ah battery from greenworks before my trip to LOTW. Drilled 25 holes through 40+ inches of ice on on the greenworks battery in -13 to -25 degree weather. Pulled both the strikrmaster battery and greenworks apart today. Both packs are identical batteries down to the numbers on the batteries. Never used a full strikrmaster battery up there. Someday I will get around to seeing a hole for hole comparison.
