I have been using pairs of A123 batteries with 2 heavy duty switches. Never had a problem but only concern is I don't have any isolation if one battery were to go south. Been thinking about some form of diode arrangement to provide isolation but then I would have to ask - which has higher chances of failing - an A123 pack or a diode?

My opinion two batteries pack connected directly to the receiver is better than diode isolation. Under heavy load a diode can either short (witch is better) or open. Remember if there is something onboard that would cause such circuit load, there is no way you would be able to land that plane unless you have two receiver.

P.S Two battery redundancy protect your system if one battery pack cell goes high in resistance (open).

Just my opinion
