I'd really say be very careful if you're going to try this. While what you say is kind of true, it's not exactly true. Even when the packs are new all gp3700s don't have the same capacity/peak voltage. And it gets worse as the cells wear out. Imagine you take two packs that were identical when new. 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.
