Yes the Protrak is a wonderful charger. Maybe it doesnīt look as good as other chargers and the old case feels a little on the cheap side but there is a new one right now. Beside this it works awesome. There are some wellknown chargers from the German brands but I prefer the Protrak.
Dimensions are about 175 x 175 x 65 mm + wires. In inch itīs about 7 x 7 x 2.6

You donīt need the thermal tray for charging NIMHīs itīs just another option. Beside this the tray is using not only one but three thermal sensors and is showing all of their readings in the display. But the deltapeak cutoff is really working good so Iīm not using the thermal cutoff even as I have one.

I donīt have the Intensive Care System. Iīm using the Robitronic system which is working really good but takes some time as itīs discharging current is 1 amps. Iīm planning for buying an additional Rayspeed unit but itīs not easy getting one currently.
