Cant go wrong with the Hyperion LBA10 or Flightpowers V-Balancer. The LBA10 is a little easier to get adapters for that are pre-made. Depending on your charger too, Like the 610iNET has a balancer built in. And both the FP and Hyperion can link to another of the same and balance large packs up to 12s. Both are capable of being connected to the charger to charge and balance at the same time.
