So I just killed my lipo pack...what to do now?

Don't forget that A123's have a 100% usable mah rating, unlike lipo, you drain them right out, which is very abrupt when it happens. So the difference isn't so much then.

The M1's yes are bulkier than lipo, but they are very light for their size, they need to shrink them smaller is all.
