I don't have any 2 cell hard packs but I do use Hyperion. You can get a hyperion 2 cell side tap(3 wires). Wire the red wire from the tap to the positive wire on the battery, wire the middle wire from the tap to the plug that goes in the balance port on the battery (you will need to get that plug from the battery mfg). Wire the last wire from the tap to the negative battery wire & you should be good to go.
