Charging thru the balance wires is accepted a limited to 2amps, so with a large capacity lipo, charging this way would take literally hours. I only charge thru balance wires when I am trying to solve a prob with an individual cell. Sometimes charging a prob cell directly will resolve its probs.
Otherwise, I balance charge using the main power leads to charge thru and balance wires for balancing.
There are a lot of Hyperion resources on the net, I guess they assume you'll find them. Heres a link about their G3 lipo care and usage -
