crystal focus 4.3 and 11.1V L ion?

[Novastar]

I think this question was actually answered recently in some thread--I don't remember which.

"11.1v" is actually >11.1v (it's more around 12.2v) on a full charge when first hooked up to CF v2-v4. It's too much for some of the components on the board.

If you REALLY need 11v (or let's say ~10.8v), you'd want to put some kind of zener diode off of the battery pack BEFORE it reaches CF, so that the pack is "dumbed down" to closer to a "true" 11v... or maybe even 10v.

Also, it's true that having a pack with greater voltage than the LED + board + speaker & components needs... WITH CF... actually does increase runtime a bit--but it's not something so ridiculously significant.

thanks Novastar, you guys pretty much put me in check on this I've decided to stick with 7.4v. Don't want to go overkill on my first try.
