I think this thread covers my question just want to make for sure. I am doing a 200 in a 1550P and plan on using a 1300mah lipo as it is a Plus size enclosure. In case that the pack will not fit my back up plan will be two HG2's in soldered to together in series. I reads in this thread that I will have to put a jumper between pin 2 and 3 on the balance socket for the charger to operate properly in a 2s config. Is this correct and is there anything else to be done to run a 133 charged internally. Thanks.
