Hey, ive got a host that supports 3AAA, but my driver needs 7-11V, i know that there is 3.7V AAA's out there. If i get two 3.7V AAA, put them in and then add 1 1.5V AAA? Would that work or do they have to be the same voltage? And if its not, how do i build a spacer to go into the 3rd spot?

A spacer can be made of almost anything stiff enough to hold up and small enough to fit the battery compartment. cardboard, wads of paper, plastic, section of a candy cane, a stick, dowel, acorn (CR123)... probably not mashed potatoes, but maybe a raw one... don't forget carrots, they come in different *widths and are easy to trim to exact length....

hey, ya know.... it doesn't even have to be Round! it could be a Square Thing!

anyhow, all those things can work, as long as you add a wire that connects two contacts, one on each end; and position those to touch the battery and contact that you're trying to connect.

That's about it. Some tech-head may try to tell you exactly how to do it, but don't let 'em take all the fun out of it for you ;-)

okay, ok... simple recipee: dowel of appropriate diameter. electrical tape. wire. 2 wood screws, to be fancy.

yeah. you could just hard-wire it if it's one of those cylindrical 3-battery holders; save-a-dowel or whatever ;-)

or you could change to a different driver, and see if a single 18650 or something will fit in the chamber instead...

Why don't you just get 3 10440's and stick them in? That comes out to 11.1 volts... Surely it's within tolerance?
I guess fresh batteries might be a little higher, but I have a hard time believing your driver would fry from that.

It creates excess heat, which can cause problems at higher voltages. It will fry unless given a strict duty cycle.

hey, sry for bring this back up, i just thought i would reply in an old section instead of make a new thread.
So my question is can i mix batteries? Can i put 2 10440's in with 1 regular AAA in? the voltages would be different (3.6V and 1.5V) so could this work?

That would be a recipe for disaster.....Do not mix battery chemistries or batteries of different voltages.

You might have a melt down or possible explosion.
