First - thanks for the thread -very informative
Now, I have the 1010B charger that I mainly charge 5S1P A123 packs on. currently two of the three packs fly in the same plane as parallel packs (doubling my mAh) and the third flies alone in another plane. I use the balancing board that came with the charger and connect the two balancing tabs to the "b" and "b1" ports and then connect a homemade serial deans adapter to the main discharge leads which then plugs into to the main output leads on the charger. I set the Charger up for 10S 2300 mAh and start charging....
Would connecting them up parallel and setting the charger up for 5S 4600 mAh be any faster/better?
