Can the battery in the Mini 2 controller be tested for voltage and it's health without splitting the case??
No, sorry as said, I don't want to open the controller up.
Probably the only terminal available would be the charge port. If you can find a pin description for that port, it might be possible. What information those pins could provide would likely depend on what DJI has allowed through that system.
Thanks. I was on my way out of the office when I saw your post and didn’t have time to hit the Google button which I use quite often.
Board has been ordered.
