It’s hard to convince me how making a high demanding cordless tool compatible only with small batteries make any sense. Imagine having a V8 sports car with a 10-gallon gas tank.
Shortly:
The "V8 sports car" from Festool is the CT26 with the SYS POWERSTATION 1500Wh fuel tank. Besides, "sports cars" do not use (heavy) V8 engines for half a century or so, those are the muscle cars you were thinking of probably.
The "Small but-still-pimped-up Japanese car" is the CTC MINI with the dual 150Wh fuel tanks.
The "400 ccm pumped up Dragster Quad" is the CTC SYS with the dual 75Wh fuel tanks.
Stop thinking of the CTC SYS as "just another small cordless vac but now from Festool". It is a 1-mile dragster with the fuel tank to match.
If that is not what you need (most folks truly do not), just let it be and look at the CTC Mini (or the CT SYS) for your use case.
