Now of course the alternator might come on at any time, i'm just not sure how this will play out.
Aha.

Well, it won't work that way. The alternator will simply try to raise the voltage of the added capacity to whatever its setpoint is ~13.5-14v.

You'll just be carrying dead weight.

If you want to leave the alternator connected and add a "boost" pack, it has to provide more voltage than the alternator puts out for it to automatically reduce its output.
