Radek, I believe the circuit diagram for the T45 battery pack is posted
somewhere... maybe on the Olympus Hardware page? Try a Google search and
check that page. IIRC, the separate circuits are tapped sequentially to
shorten the recycle time... while my battery pack holds a charge for only a
relatively few flashes (~50 was when I stopped) it recycled very fast from
any 'auto' or TTL setting, and only took about 10 seconds from a full dump
flash each time. But the flash tube started to get hot, so I quit.
