The larger battery does not increase the usable power of the 2101.
It will increase run time.
The higher torque mowers have more powerful motors,drain a battery faster thus they come with larger batteries to maintain run times.
I've got a 2101 too....
I'm a bit disappointed in its power.
Looking back I regret not buying the most powerful push mower they make.
I have the snowblower,blower,weed whipper and chainsaw.
The mower is the only one I'm disappointed in.
Suction is horrible.
