Does the battery on this connect on only two wires? I can't keep track of which Onyx models do this. Using only two wires is not typical of modern practice. At the very least you want a temperature sensor directly on the battery, maybe some sort of battery identification system.

If you want to run anything without battery, it's better to inject power at the battery incoming point rather than using the USB connector.

There are three wires. Positive, negative and I don't know what. There is no temperature sensor connected directly to the original battery - only the two terminals.

The white wire is probably the temperature sensor. It's mounted on the BMS (battery management system) PCB under the Kapton tape.

It's interesting that that's the second Onyx I've seen with both solder spots to tack solder the wires and a nearby connector.

The Poke3 uses a high density (0.4 mm pitch) mezzanine connector for the battery. I've no idea how many conductors it's actually using.
