Hi guys. I think Flir one's on-board battery is an unbelievable bad design, it's not only compeletely useless, adding more cost, also users have to worry about a separate battery level, wasting more power to charge it, and not to mention sometimes the connector will loose make the thing not work.
I suppose there's a chip similar to those inside phones, preventing the whole thing from booting while the battery is absent. Have anyone ever tried to remove or skip that chip, to make the dongle just work like other USB thermal cameras?

At least one forum member has stated success with removing the battery and directly connecting the battery input terminals to the USB 5V rails on the USB connector that plugs into the phone.

Hi guys. If you remove the battery from a imager Flir One Pro Gen3, will the imager work without a battery when voltage is applied to the Type-C charging connector?
-
no it wont work without battery., tried.
-
Maybe try with a big capacitor instead, and possibly a resistor. Something just to persuade the charging circuit to fire up and deliver 4.2V into something it thinks might be a battery.
There is nothing clever there, the battery is only a 2 wire connection.

strange but 3 wires are from battery.

Must be differences as they went along then, mine is 2 wire (open on bench now). May explain why the other one worked on 5V too.
Can you work out what the 3rd wire is for ? If you are lucky just a thermistor
Hopefully 3 wires are a bit less likely to fall out as well.
