RE: 9.6v vs 7.2v
Guys...
I'd have asked " Where in the pack is the tap " as that will tell you the voltage needed by the 'limited' components. If this 'limit' is under 7.2v, sure, you can safely dispense with the blue tap, and just go red & black all the way.
If it ~isn't~ under the limit, perhaps a 5v regulator (like used for electronics boards) is called for, or a dropping diode or two. There ARE better ways to do this that critically unbalancing a battery pack.
IMHO.
