Replaceable battery mod with USB passthrough

[6steelstrings]

I was about to pull the trigger on a Pioneer4U ipv 5 when I discovered that the USB port is for firmware upgrades only.

Can someone suggest a mod that uses USB charging?

I do believe the PICO uses external 18650's and has passthru charging. I may be wrong though. I don't own one but it's on the top of my get list right now.

Yeppers. Who_Dey is correct. My wife and I are running two of them.

The Pico and Istick TC 200w do this.
