Run one pack for a few hundred cycles at high current and it'll lose capacity (the cells wearing out). Now if you try and charge those two packs together the worn one will overcharge before the new one is full.
Like I said, if the mismatch is small, you'll be ok. After all, cheapo unmatched packs don't explode when you charge them. But if the mismatch is bigger you're inviting trouble. Unless you have the tools to know whether the packs are well matched I'd say don't bother trying.

yes it is there is as much chance of one cell expolding etc in a 6 cell pack as in a 12/18 etc pack
boats use far more cells in one pack thean we do!
