If you charge one battery at a time, there will not be any issues. Or if you want to charge both batteries at the same time, just disconnect ONE of the batteries from the receiver/power expander. This eliminates the common ground issue.

My A123 batts each have a seperate charge/balance lead so i dont have to disconnect them from the rx. The leads are stubbed off so i can get at them and hook up two cellpro 4 chargers. Chad is correct though, they soak up a charge so fast i typically just do one at a time.

Even with the balance tab as a charge lead you still have a common ground.....I think.
