Oh poop! You're right Eastern--I *WAS* thinking more along the Li-Ion side there. BUt hmm... I think then that is even MORE reason why using the buckpuck
in this case... is nearly irrelevant if not a waste.
Why am I saying this? (for those who are reading and are new)...
Well, we have:
7.2v (Batteries)
~7v (LED fwd voltage)
=
NO waste of energy, especially if a super tiny resistor is used. And you know what--just like Eastern said--in the case of 7.2v Ni-Mh... you probably wouldn't even WANT a 1 ohm resistor in there... you might want 0.5 ohms or something, just for protection.
However, if the buckpuck was added... all it would do is suck a little bit more power to give current regulation... which won't really be necessary since the cell + LED voltages are matched so nicely.
