Topic: Remote Battery

[Mattk]

Just stating the facts 

And of course 6.2v won't do any damage, Davis's own gear puts out 6.8 volts.

Not real sure why 7.5v was even raised relative to the question?

1.3mm, centre pin+ would be about right. Also if being used in the ISS then the jack is best to be a 90 degree or if straight then very short with no cable restraint, mostly just use the jack, throw away the screw on plastic cover and heat shrink

Actually it's  a 3.5x1.3mm plug. I just got done doing an AC conversion.

"You would unplug the solar and remove the battery. Then plug the power adapter into port 2 below"

Has anyone tested if it is also works to have all three (external battery, solar power and internal battery) connected?

I have AC, battery and supercap connected and no issues. However, Supercap does not seem to charge without the solar panel. The CR123A I think would make sense to keep, because if the mains power goes out you still got something that can transmit if your circuit to the station fails, or everything fails and you have your console on battery backup or something.

Thank you!
That was good to hear. I was also worried about having only one power source in case of outage on the grid.
May I ask what voltage are you delivering to power jack on PCB?

[azchrisf]

5.5 volts DC
The jack is spec'd for 3.3-6V IIRC, same as the Davis power brick for the console.
Tip is positive on the jack.
