I am sure that the guys at Festool HQ are looking at this but is it really needed?
How many of the professional woodworking FOGgers find that they do not have enough power to last a full day assuming that you start out with a pair of fully charged batteries? If you answer this question please state the tool model or its voltage and the Ah capacity of the batteries.
I no longer do very much serious woodwork away from base (too busy with the magazine and video work) but I was always let down by the low capacity of my old NiCads on my cordless drills (one each of drill-driver, combi drill and impact driver which are still in use). I have been lucky enough to have been allowed to use the Hitachi machines, seen in my latest videos, for over a month and they really do have loads of power. I have not been able to play with any Festool rechargeable kit and so cannot make any comparison. The current Festool kit might be better than the Hitachi machines if they are more efficient. Until I test them I have an open mind (hint!).
