TUTORIAL – Li-Ion & LiPoly tutorial. Power packs to propel your projects! – If you want to take your project portable you’ll need a battery pack! For beginners, we suggest alkaline batteries, such as the venerable AA or 9V cell, great for making into larger multi-battery packs, easy to find and carry plenty of charge. If you want to go rechargable to save money and avoid waste, NiMH batteries can often replace alkalines. Eventually, however you may want to upgrade to the shiniest new technology – rechargable lithium ion/polymer batteries…

  1. Great tutorial! One slight mistake I found under the “Protection Circuitry,” section:

    “On the batteries we cell, the protection circuit is soldered onto the battery”

    I believe you “sell” the batteries 🙂

  2. Love it!

    But I found this odd: “You can change the charge rate of each charger by soldering an LED into slot R4 (for the USB charger) or RPROG (the USB/DC charger).”

    Really? An LED into slot R4?

  3. typos fixed

  4. Pay close attention to the safety, charging and handling warnings on Lithium batteries. There are fire resistant safety bags available. Nothing’s so fun as having the inside of your garage coated with a black powder and going to the hospital for observation from breathing the combustion byproducts while trying to valiantly stamp out the fire. (True life experience of one of my modeler friends.) The other fellow had his handicap equipped van burn to the ground because he had LiPo’s on the quick charger sitting on his seat. We smelled smoke and turned to see the seat fully involved.)

    OTOH we’ve never had problems with Li-Ion batteries.
