I will second the idea of using a Drok Power Supply.? I bought a 10 amp 12vdc adjustable Drok wire frame supply from Amazon.? ?I run it at 7.5v - about the same as the two batteries would provide,? ?It seems to be very clean ad holds the voltage very steady.
?
I had tried a 9vdc 5a brick power supply that was made for a computer. While it did not have any RFI that could detect, the zBITX ran pretty hot with a 9v supply, and the voltage dropped quite a bit whenever I transmitted.? It seemed like 5a wasn't quite? enough.
?
And, I also found out that the JESSPOW 18650 Flat Top 3300mAh Li-ion Batteries that Amazon sells are good quality.?
