I imagine that if you used a digital voltage comparator, operating at high frequency, that would monitor the input voltages and "forward bias" power from the stronger pack, instead of an either/or situation, you could closely regulate the voltage level from both packs, thus effecting a "Balance" throughout discharge. I've checked my Powerbus 40-24 inputs from the battery packs after coming off charge. . one pack is always slightly higher than the other, but after 2-3 flights both packs read the same, and this continues right down to my 6.1 vdc bottom limit for the packs. Not having the exact schematics or logic diagrams and flow chart parameters, and not being able to pick the circuit apart, it's kind of hard to refute the MANUFACTURER's claims. This is what is claimed by Herr Deutsch, and what I have actually witnessed through a few discharge cycles at the flying field.

I'm going to do 4-5 flights each with both planes this weekend, and will be doing "Switch on, servoes idling" voltage readings before and after each flight, to track the output voltages of the packs, and see how well they are being regulated by the power boxes. I just hope I can outlast the battery packs.

BTW, I just got off the phone with Gerhard. . the special "Logic" switch for the Competition powerbox units actually carries 100% of the current from the batteries, unlike the switch for the EMcotec, which is a TRUE logic-switch and controls the box itself.
