    Series AND parallel?

    Just hit me... To drop the voltage down, I got it. Thank you!

    Series AND parallel?

    I ended up going with this batt. pack + charger: http://www.overstock.com/Electronics/Nikon-S3-S5-S6-P2-P1-EN-EL8-Coolpix-Battery-and-Charger/4384372/product.html?CID=208011 Its the closest one I could find that met the size requirements, in addition to being dirt cheap. So I think the...

    Series AND parallel?

    Ok, so assuming I go with a lipo pack (which seems inevitable after the wisdom and advice provided), how do I wire it? I've never worked with either lipo packs or diodes before.... You guys have been great, I can't thank you enough!

    Series AND parallel?

    True, the batteries do output 1.2v (2.4v combined), but this is sufficient to power one the lasers. I popped them into one of the assembled units and it works, without a detectable difference between using regular alkalines, so this may not be an issue. But the charger issue is spot on, so...

    Series AND parallel?

    There are only 4 batteries, the 5th battery on the schematic is actually the wall charger to charge the batteries, I just couldn't find a wall charger icon in the schematics program. Additionally, the two switches can never be on at the same time, either one will be closed and the other open, or...

    Series AND parallel?

    I'm building a project that has 8x 5mw lasers, each requiring 3 volts. To power the lasers, I have 4 AAA rechargeable batteries. They are currently wired in parallel, as that is how they are wired when in the charger. I would like to wire the batteries in series to achieve the 3 volts total...
