A123 charge rate?

Ouch. Well, I should mention that my 7s packs are made up of a 4s and 3s in series. So I guess I can charge them separately at the 10A rate and put them together, which is what I've been doing currently. Just wanted to see if there actually was a charger that was capable of charging the 7s packs at around 10A.

While I'm on the subject, I don't suppose there's any way to connect the balance taps of the 3s and 4s packs together so that if I decide to charge them as a 7s pack, I can balance at the same time?

I suppose I'd have to be very careful as to which way I plug the 4s and 3s packs into the series connector so that the balance connectors are also correct, but it should be possible right?
