How about these at HC:

Rhino 360mAh 2S 7.4v 20C
Rhino 360mAh 3S 11.1v 20C
Rhino 460mAh 2S 7.4v 20C
Rhino 460mAh 3S 11.1v 20C
hexTronik D9 Gen2 350mAh 3S 11.1v
Polyquest 400mAh 2S 20C
Polyquest 400mAh 3S 20C

They are listed among much larger sizes. I'm pretty sure HiModel China also has the smaller sizes, but I think they can't ship lipos until the Olympics are over, probably just a few more days. Hope this helps.

P.S. Yes, HiModel has 200, 300 and 450mAh:

I've had good luck with them. Their cells are still going strong.
