I bought these 450 mAh 1S packs recently for the C186 / MCPX brushed motor project, but took notice that the appear to be the same size as my 360 mAh packs and noticeably smaller than my 380 mAh and 400 mAh LiPo's.

So I used a battery capacity tester to measure the actual capacity of the packs and discovered they are indeed only 360 mAh. Seeking an immediate refund. My only regret is that I gave a positive feedback already.

BEWARE THESE BATTERIES!
