Just searched, I had previously figured out they are 7.4v, which is two Li ion cells in series. I imagine packs like that are pretty easy to find.
Now I just have to figure out what the connector is. I'm pretty good at that, I just haven't had the energy.
Two Li Ion cells in series can be over 8v, freshly charged could be 8.2v. When run down, closer to the 7.4 you cited.
Some of my Li Ion batteries for a DSLR camera (Pentax K-30) are two cells in series in one battery pack. The battery charger for that battery pack is labeled 8.4v output.
