The first pic would cause problems. The "ground" point from the BEC feeding the LVC is floating at 1/2 total battery voltage. Since the LVC sees the whole pack voltage, it might totally short out "battery 2", unless the balancer inputs were isolated somehow from the rest of the LVC circuit.

The second pic looks like it would overcome this issue since all ground references are at an equal level.
