Fully charged packs don't stay at 4.2 volts per cell very long. On the other hand, once the initial charge voltage is burned off by a constant load, the voltage loss curve "flattens out". What if you put fully charged 6S and a 5S packs in series and "burn them down" to 3.869 volts per cell (a total of 42.56
volts for an 11-cell pack) so they were legal for use. Would the voltage of this depleted 11S pack be higher than a fully charged 10S pack at the end of a typical flight? If the end-of-flight voltage might be significantly higher for the 11S pack vice a 10S pack, it would be worth investigating, even considering the extra weight of the additional cell. Come on you electronic gurus, show me where I'm wrong.<BR>> <BR>> Ron Van Putte<BR>> <BR>> On Feb 28, 2010, at 10:00 PM, James Oddino wrote:<BR>> <BR>>> What comes after ...?
