my 900mah 2 cell lipo, took a full charge the other day of 1044mah. how the hell does that work?

My 4600 NiMh will charge to over 5000. It's not uncommon for the cells to attain more capacity than is stated by the mfr. Back in the day, I used to get 2200+ out of some 1800 NiCad cells when I'd charge them w/ my Tekin BC112C.

To you I say, bonus!

X2 the cells are all slightly under rated.

a Lipo should not be taking that much charge, a lipo is nothing like NIMH or NICAD, if you are getting that much over on the charge something is wrong with either the charger or you have a mislabeled battery, or the cells were totally drained not a good thing either..

typically when charging lipos you never reach the full MAH anyway, because the cells should never be fully discharged ..

Ahh very good point - I should have pointed that out in my OP.

10% +/- on a lipo in its first couple charges if you totally drain the pack is not unheard of and common. Just keep an eye on the pack for puffing.

hopefully you are balancing the cells
