On a completely different note, how do people manage so many different battery systems? I watch Matthias Wandel and he seems to use every kind of power drill under the sun. The battery management would drive me mad. I had settled on Makita 18V with various adapters, only recently adding Milwaukee M12 because the tools are too good to miss out on.
I've got my chargers mounted on the wall, all together, and 2 shelves for batteries right next to them. I rarely keep batteries in the tools, so the habit is when I grab a tool, I also grab its battery, and when I put the tool away, the battery's taken out and put on the shelf or charger. So no matter what tool I grab, I know right where the batteries are. I don't have to go looking through my tools to find one with a battery still in it, and hoping it's charged enough. If I need to use my M12 small recip saw, I don't need to remember where I put my oscillating multi tool because that's the last time I used that bigger M12 battery...it's on the battery shelf.
The only real bummer is weight...let's say I'm grabbing three tools...I might
have to bring 3 batteries, depending what the tools are. Maybe I've been lucky that I've never gotten to a location, and realized I grabbed the wrong (or not enough) batteries. But if i travelled to more job sites, and had to travel with multiple brands' batteries AND either extras or chargers, that would get heavy and cumbersome...AND you'd have to make sure you had access to three power outlets (which isn't always the case) or having to also bring a power strip...which is also annoying.
