Help!

I run my Oudie from my V7 so that it gets all the flarm data from my Flarm Core. Unfortunately it tends to run out of battery power towards the end of the flight, even though the V7 is supplying juice.

I measure the current draw of the Oudie in this setup and it came in around 160ma. I then plugged it into the Colibri II connection I have a s a GPS backup, and it then drew 360ma. The red charging light also came on. I moved it back to the V7 and the charging light went back to green and current again dropped to 160ma.

Conclusion: V7 output is current limited and starving the Oudie in flight.

Solution: so what I need is power from the Colibri II power supply, but data from the V7. Anyone ever done this? I could make some funky splitter cable, but I am worried about ground loops between the V7 and the Colibri II power supply.

Any suggestions or experience solving this problem?

Thanks,

Matt
