Has anyone used a 7.5 Ah and 5.0 Ah for the snowblower? I have the self-propelled lawnmower with 7.5Ah battery. Lucked out today on an EGO snowblower (no batteries) at Goodwill that came in on a pallet of equipment. Looks brand new (may have been a floor model at Home Depot they are clearing out for summer equipment). I called EGO; they said it needs a minimum of 10 Ah and that a 7.5 and 5.0 in combination would work. Just wanted to find out if anyone has used this combo and how it worked for you.
