Has anyone had success powering the R3 from batteries?
R3 does not support battery
post your build? how are you hooking things up?
I have run my R3 from a battery USB phone charger. The particular USB battery I use has three ports, each will produce 5v @ 2.5. I then use two of those ports with 2 x 5v -> 12v USB step-up adapters. They will each produce 12v @ 1A. I then wired them into parallel to power a single plug which I can run to the R3.
no on full load transferring many files large or small…

Whenever I try to connect the M2000 via USB(which happens to be a device that can charge other devices through its usb c port) and the Note 20 Ultra 5G into USB the R3 reboots and will not come up without boot loop unless both USB devices are removed.
Out of four different 12v stup up devices this is the only one to boot up the BP-R3. DROK USB Cable DC 5V Boost to 9V 12V Voltage Converter 1A Step-up Volt Transformer Power Regulator Line with LED Display
There is also a HIGHROCK 30cm USB 2.0 a Power Enhancer Y 1 Female to 2 Male Data Charge Cable in use with this setup as well.

- have two, both when on full load transferring files via wifi between multiple machines the device will reboot.

misc pats for this build I also have:
-MCP73871 USB 5V DC Power Boost Solar Lipoly Lithium Lon Polymer Charger Board 3.7V/4.2V Battery Management Charger Module
-1.5A Multi-function Mini Boost Module Step Up Board 5V 8V 9V 12V LED Indicator Diy Voltage Module 3.7V lithium battery boost

chenyang CY 50cm 9Pin 10Pin Motherboard Female Header to Dual USB 2.0 Adapter Cable](https://amzn.to/3JbI7dY) is what I use for USB to pin on board.
The goal is to have 40000maH with a USB-c charger that has pass through so when its in my car its all ways topped off and if I ever need to take it out and throw it in my backpack I know it’ll run for 6-12 hours easily.
My setup works quite well at all loads. The draw of my R3 has never exceeded the ~30 watts my setup will supply.
Well, after going through two of those USB power boost line DC 5V to 9V 12V Step UP Modules I’m done with them.
Now the LM2596S-ADJ 3-40V DC-DC adjustable step-down Voltage regulator power supply MODULE BOARD is powered from a Ryobi battery just fine and when transferring large files via wifi the R3 no longer reboots.
It’s set to 12.2V which is what I measured coming off the included power adapter for the R3.
