I only want to carry it with me on trips to monitor my cells now and then. I dont wanna go through the hassle of connecting my pack to it. I only need to monitor for a moment or two then put it back in my bag. I wont be using it for charging. So looking to use a small battery with an XT60 connector.

Says it needs minimum 7V, so a 3S 18650 pack of whatever is around should work fine. Even 2S should work, though it might shut off before they're empty.

Wouldn't it be easier to just carry a celllog or something similar instead? Would probably cost about the same as the battery you need.

The elegant way to do it would be with a QC3.0 battery pack (you can get them for $30 on Amazon) and program its output to be 7 volts.

Would a portable battery bank for smartphones work? I could cut the end of a usb cable and attach an xt60

Yes - BUT - to get to output 7 volts it has to be a QC 3.0 supply and you have to spoof it with a little controller. Not the easiest thing to do. But elegant.

But isnt 7V the minimum input voltage? It ranges from 7 to 32V so shouldnt a normal unmodified battery pack do the trick?

I would just go with a cellog style meter and balancer. Simple. Now how to find a good one ? AS I have 5 of Them 3 different styles. All cheap but do work. Not the two hyperions. bad. To easy to back charger on the road.
