Charging 4 saddles at once?

[Cardnim]

OK, probably a stupid question, but thought Id ask anyways.

Ive jsut moved from stick packs to saddles and tonight will make up a balance lead so I can charge each pair of saddles as a set (i.e. 2 saddle packs on charge at once, just like my old 7.4v two cell stick packs)

However, it occurs to me that a saddle is just a single cell lipo that we put together to create the 7.4v we need; and if we can do this for charging, then surely I can put ALL FOUR of my saddle packs together using linkage wires, and then balance charge them all at the same time as a 4 cell lipo battery.

My thinking is that as long as the batteries are all wired in series (i.e. not parallel) then it should charge fine.

Or am I just stupid?
