I have a Metz 60CT-4, complete with Metz power pack. It works great. My backup unit is a Metz 45CL-4 with Quantum Turbo power pack. I'm wondering if I can use the Quantum Turbo with the Metz 60CT-4 flash head, and the Metz power pack with the Metz 45CL-4. I measure the output voltages from the Metz power pack. They are 350 VDC and 7.5 VDC (I'm using a 7.2 V LiIon battery). I have not measured the output from the Quantum Turbo, but from what I read, the outputs are 335VDC and 8.4VDC. I can easily make the cables. Have any of you something done this? Thanks.
