Kits that don’t include a charger but DO include batteries.

For example. I’d 100% purchase the OSC18 kit that comes with the battery, but I definitely don’t need nor want to pay for yet another charger. I think I have three airstream chargers at this point and one old charger from my T12+3. I’d love the new battery pack, but really hate the idea of not only paying for another charger, but also contributing to overall e-waste that that kind of purchase produces.

I’ve bought many (10+) Milwaukee kits with chargers I don’t need. Easily sell them locally for $20-25. Makita 36v kits (4+) I sell the chargers for $60.
I recently scored a ETSC kit with a Charger I didn’t need. Sold it on eBay for about $55.

I understand your desire to buy more kits without stacking up chargers I’m just letting you know they are relatively easy to pass on, not create waste, and I wouldn’t let that stop you from buying more tools.

You can only choose between a basic tool-only kit, or the full set with everything included.

It is always easy to sell off Festool things that are not needed, like your chargers.

Wait for the next 'get a free battery' promotion?

The charger is cheap, not much environmental impact either.    If they didn't include it, you would have the problem that if you want to sell the tool to someone without any charger, now they have a problem.  Maintaining a SKU of every item with/without a charger would be a logistics PITA with little/no value. The systainer and insert would be the same, try selling it and someone would yell you left the charger out and demand a charger.

Other companies sell bare tools, no battery or anything, these make a lot of sense if you are adding to a system.

If environmental concern was big, one would skip the battery tool and just used a corded.

Having chargers with every tool/in a systainer is nice in that you might not always be in your shop, you might be someplace else with a small sub set of tools, having some chargers all ready packed up is great.  Might not use them often, but when you do, you be glad you have them.
