I currently use an old Ozito 36V 3AH mower, Ryobi 2-stroke whipper snipper and Homelite 2-stroke blower. The mower works fine but the battery is on the way out and they don't make the batteries anymore, so need to upgrade. I also want to upgrade the 2-stroke tools to battery operated. I have a small 800 square block to maintain and am perfectly fine doing over a two day period if battery needs charging.
My main question is what would be the best budget friendly brand / option to get me these 3 tools interchangeable with batteries. Running the same batteries would be a big saving if possible. From what I see looking on bunnings etc is the whipper snippers use a different AH battery so not interchangeable with mower?
