I've just looked at the Talentcell web site since many OP's have said they use them.
It looks like their LiPo units could be outputting as much as 12.6 volts at full charge. ( and the LiFe ones even more! ) according to a quick glance at their tech specs. And that the voltages will drop during use ( as would be expected for the typical discharge curves for a particular chemistry).?
Am I wrong on this or is there built in Buck/Boost circuitry in them to provide steady output voltage?

I operate mostly from my shack also. I just use a Talentcell battery pack and just charge it when I shut down for the day. I have used this for about a year with no problems. This way I know I will not over voltage by little gem.
I expect to mostly operate from my shack where I have a [nominal] 12V (really 13.8-14.6 VDC depending on whether or not I'm charging my LiFePO4 shack battery) distribution panel which is clearly too much for the QMX+. I've been thinking about using this though I hope to find one that has a narroweradjustment range so that a "slip" of the hand doesn't fry the radio. Adding series diodes to power from the distribution panel is problematic because of the power range I use.

I'm not wedded to this approach and would appreciate advice or any other approaches that you have used.
