All Lion batteries have circuit protector so it doesn't overcharge.

Take a look here. But if you buy two batteries you need PCB based on 7.4V and charger also based on 7.4V

I ended up going with 2 6000mah lion camcorder batteries - I already had 2x2-slot chargers for these batteries, the ones I bought were 7.2v and I hacked a nikon battery to get a bit of extra juice (and theorectically allow me to swap batteries during a shot).  I did manage to kill  one in the process though - a lip of the soldering iron.

One 6000mah battery gave me about 1500 shots. A bit less than I was hoping for but good enough

thanks for all the help folks!
