I had the $50 iFi iPower 9VDC wall wart on the microRendu and I also tried a couple 6VDC cheapies from Amazon ($9 and $12). They all worked fine and sound about the same which tells me there's nothing really special going on in the $50 iFi.
I may try a couple 18650 or 26650 Lithium Ion batteries in series when I have the time. I already have a few of them plus the battery holders. I'm gone all next week on travel for work so that will cut into my play time. ;-)

You'll note there are no recommended conventional (non-ultra or supercap) battery supplies for the unit.
My understanding is they do not offer particularly low impedance.
The power supply list on our website is just intended to be a good starting place. Feel free to try other power supplies as long as they meet the minimum requirements of the unit.
I'm sure there are hundreds of power supplies and batteries that will work wonderfully with the µRendu that are not on the recommended list.
As for Lithium Ion batteries I suspect you are correct. Relative to a NiCad or Ni-MH battery the ESR of a Lithium Ion battery is higher, but I don't know how much higher. So I'll try some Ni-MH batteries. ;-)
