Sure I know. But still, it is no magic, quite simple actually, and definitivly nothing revolutionary. Handling parallell connections is a quite simple match technically. And maybe betazone's original question is just about a single flash unit, where usually 2 or more batteries are connected serially, which is the most common way. That was what I was assuming anyway. Just as a matter of private interest, I once opened one of my laptops battery pack, and there was a whole complex electronic circuit inside the battery pack. And yes, even in my laptops (ever since my first laptop from 1995) you can actually put in two packs. Which explains why I could even imagine Canon to have some magic battery there you can actually connect them serially and it may still be OK even with gross charge differences between packs. I think that is possible to handle also, if they for whatever reason would spend an effort on it. Just imagine, batteries that have no polarity markings. A revolution that enables 3-year olds to change batteries in toys.Artosoft said:You are welcome .
But you know ha, can not just suka-suka put battery in parallel. Must have a regulator/controller circuit. A simple one is 2 diodes on positive of each battery.

BTW, I think just diodes is not a very good solution (simple and working though), it would give too high voltage drop over the diodes, which I am sure you know. But again, it depends on the voltage of each battery pack how that drop effects the overall performance.
