Is there any point in lots of batteries on a CommSat?

[Skorj]

All this time I've been playing, I've put large batteries on my commsats - large enough to relay large amount of science without running out.  But that's not needed, right?  As long as the commsat is out of physics range when I'm transmitting science, it doesn't consume electrical power? It seems obvious now that I say it, but I've been building RA-2s with huge battery packs for so long that I forget why I thought I needed to.

You are correct. The only reason to put batteries on a comm sat over those required to get it to its destination (usually 0) is if that sat is also fulfilling some contract that requires batteries on the craft.

Thanks!  That will sure make deploying a swarm of RA-2s easier.
