That makes me wonder about the possibility of a decent Nicad replacement
technology for recharging flashes.  Take the T45, for example, your choices
are low voltage packs (4.8vdc) with five parallel strings of near-zero
resistance Nicads, or a high-voltage external pack with transformers.
Either way, the nice super-lightweight lithium-ion batteries need not apply
as they can't recycle a high-power flash fast enough to be usable.  Besides,
when you do try to apply high-current usage to them, it essentially destroys
the cells.

But this is extremely good news about this development because the same
mechanism that allows for fast charging also allows for high-current
drainage without damage.
