I have an old Sunpak 611 in great working condition. It fires up using regular C batteries n off the wall adaptor but I want to rebuild the CL-1 cube with new NiMh sub C cells. I don't have the old batteries in the cube so I have no idea how the thermistor(s) was hooked up. Anyone have any ideas or perhaps have an old CL-1 cube I can compare it to for wiring? I put a set of NiCads in the cube without the thermistors n it charges just fine but I am worried when I get the new NiMh I am running the risk of overheatting em. Any info is appreciated.
