New Mafell saw

[Lincoln]

Mafell are releasing their K85 saw, in a dual battery, 18v, version in January. This is the equivalent of Festool's HK85 saw = 85mm depth of cut, 60* tilt, runs on their standard tracks and cross-cut tracks.
Will be interesting to see which battery they recommend with this size saw - from memory, 5.5ah was the one to use for the plunge saw. They now have high power 10ah available to them in the CAS system.

The Metabo CAS 5.5 amp battery weighs exactly the same as the 8amp version. I can’t figure that out.

My suspicion is that we'll soon see tab-less batteries become widespread, allowing higher performance out of the same size of battery.

Makita has already released a tab-less version of their 4Ah 40V battery, apparently it has the same performance as the much larger 5Ah and 8Ah batteries, but in the meaningfully smaller 4Ah size.

I have  tried an 18v - 5ah a few  times  in my  milwaukee  circular saw  and  fully charged  its  pretty  much useless. Just no reserve.
I always  reach  for  the  12ah.

And would  question  the suitability  of  such a large  saw  using batteries.
I use a HK85  quite  a  lot  and  usually  in the workshop and I would  never swap it  for  cordless.
I cut plywood  stacks  full depth  of  the blade.
No  battery saw  can handle  that.

Don’t know if they have what you need but Metabo still makes some of their tools in Germany.
