This is video showing the power difference of the 18v Ryobi ONE+ High Capacity battery , (part#) P108 4AH , it really can make the tool perform. On the right you have the New 300ft-lbs P261 impact wrench using a 1.2AH compact battery and on the left you have the old model P260 impact wrench that puts out 200ft-lbs of torque using the extended capacity 4AH P108 battery. If the speed difference isn't obvious ,the big diffence can be seen in this video where a compact battery could only drive 1 lag bolt before shutting down [ Ссылка ] where as the 4H battery still has full power to do more work. And of course I can only say this for lag bolts and no promises the older model would perform so well when it comes to automotive nuts and bolts.
