missileworks RRC2+ Altimeter battery

[Bryshereyy]

Hello all.
I've just finished building the Loc black Brant and using the missileworks RRC2+ Altimeter. Can I get some suggestions how to make some sort of charging port that's accessible from outside the rocket instead of having to keep opening up the electronics battery to charge it. It uses a9v battery thank you

You could install a panel-mount DC connector under/on the avbay switch band wired to your battery. Make sure your altimeter is disconnected while charging.

That’s probably the simplest thing to do. A USB would work, too.

Or a magnetic option-
