Electrically speaking it is not an issue. You will have two loads connected
to a source in parallel. A simple Y adapter can get you going. Use good
wire and connectors rated for the total load.
The key thing i would check is the battery current rating, often listed as
the C rating on consumer lipos. Determine your surge current and steady
current. I assume the rrc3 you are using is for ejection charges as well.
Add the rrc3 max current during the ejection event and the egg timer
current. As long as you are under the C rating for the battery everything
should go well. Steady current (not surge) in practice for me does not
exceed 60% of the battery current rating.
I'll see if I can find the ratings for you tonight. I use the rrc3 so I
should know that alteady....

Mike,
I'm assuming you're talking about a rocket where you're space
constrained. It's doable. I had a 38mm rocket that I put a TX and a
Quark in. If the battery is fully charged, and you don't have to wait too
long on the pad, there shouldn't be any issues.

Any (good) reason not to use the same battery for an altimeter and egg
finder? I have an av bay with a Perfectflite Stratologger and one with
a Missileworks RRC3. I was thinking of adding an eggfinder and using a
2S lipo, 400mAh to power them both. The altimeter would have its own
power switch so I can let the tracker power up and lock in before going
to the pad.
Thoughts?
