Hi J-P,
Sometimes we see what we want and do not see the rest.
That 'Hint' says a 'bec' !!
The guys are talking about a 2nd battery , all be it a BIG one or in fact 2 cells from a BIG battery.
I will leave you to work it out.
Edit; I believe that the Emcotec Dual batt unit is the ideal way to use Chris's and Jim's idea - which is just brilliant for anyone that may be tight on the weight limit - like me.

This is the post I had started when I was interrupted by a phone call:
We need someone to jump in and tell us who came up with the idea originally to tap into the balance connector.
Regarding the Emcotec Dual Battery unit. It sounds as though the batteries are isolated from each other somehow but it is not clear how the one that is at a higher voltage will charge the one at the lower voltage. It sounds like it does and that could be a problem. If the motor battery gets too low the small receiver pack will try to recharge it. If this is so, it seems almost certain that the receiver pack would end up at 7.5 volts or so at the end of flight. Maybe that is okay as it is close to the storage voltage but if it goes much lower it won't provide much margin. What do you think?
