Over time they will build up surface corrosion which causes high resistance which causes voltage drop which causes apparent power loss.   Ask me how I know this to be true!!!

That seems unsafe to me to have the batteries connected to the motor without an external physical circuit breaker but I'm probably overlooking some capability that can be set up using a Futaba 14MZ.  With the advanced planes that are a little awkward to a carry around armed and where the hatch has to be screwed into the fuse for extra canalyzer security it seems like an accident waiting to happen this way.
