There are a few large vendors to choose form though. While you have to choose your battery system up front, there are some good choices. the vendors have to compete as well as for companies they have stuff and batteries break all the time so if one vendor is a problem they just move one crew to a different system and distribute their old stuff to other crews. Or just start buying the new vendor for all crews and when not much of the old stuff is left throw it away.

Note that the above is about professional grade tools where you will find is useful to be locked into a battery system. For typical people have a drill on a different battery from the blower isn't a big deal, just buy a couple batteries. When the battery wears out in 10 years buy a whole new tool with a new battery.
