I use an Emcotec dual batt,, switch/reg,, . It monitors both batt's and takes from the highest voltage source.

Are you sure ?
Below is the Emcotec DPSI Micro – DualBat spec.
The DPSI Micro – DualBat serves as redundant power supply in RC models. Redundancy is accomplished through two connected batteries. If one battery fails, safe operation is assured by the second battery. Usually both batteries are equally discharged. Furthermore, due to both batteries being “parallel”, current drawn from the batteries is cut in half; therefore, batteries with lower capacity can be utilized.
