Uconsole A-06 shuts off when 4G module enabled

I’m having an issue with the 4G module on my A-06 uconsole where the system shuts off when running on battery power. As soon as I enable it using uconsole-4g enable the system powers off within 5 seconds or so. However, when charging via USB the cellular functions work great after upgrading the firmware and I’ve been able to use the internet, send/receive texts, etc. How should I go about debugging this issue, logs, etc? Thanks!

Potentially your batteries aren’t good? Do you have spare 18650’s lying around you could try swapping in?

Sudden big current spike causing a voltage sag in the battery? You could try measuring the voltage on the power supply and see if it dips when you turn the 4G on.

If you’ve got batteries with built-in protection maybe it’s a little sensitive to how much current is drawn?
