Use your Pro 2 with an external battery instead of internal battery, in addition to internal battery or with a second external battery. This 3 advantages: 1. It is 13 lbs lighter so easier to lift; 2. You can leave the machine in the car and only bring in the battery to charge; and 3. Replacing batteries only takes a few minutes.
