I can't find the formula right now. [:'(] But I have never heard of anyone charging a 2200 pack to 100% in less than 20 minutes. There are limitations to how fast you can safely put electrons back in a pack.

The problem is unless you have the balancer slaved to charger you cannot (or should not) charge it as hard (more than 1C). No charger, I know of, supports multiple balancers attached to it.

Most people I know that are heavy in to electrics have a generator, multiple chargers, with many balancers, and many many packs. Everyone has there own system.

I did find out, while looking for the answer for you, that my 1010 with connected 210V does safely support the charging of my 6S 4900 Evo packs at 8.25 amps! This is well above the suggested 1C charge of 4.9 amps. The intelligent/connected charger/balancer allows this to happen.
