  • These Ryobi 12V DC Battery packs have an easy connector to tap into their power. Cheap and lightweight, can power many different accessories for hours and hours. Just gotta finish up the wiring...

    I haven't done any real battery testing to see if the 3800mah /12V DC specs they list on the website is actual, but they do hold a charge and power up all my accessories for quite some time. Fairly light weight so all it takes is a bit of Velcro to hang it on the back of your Lilliput LCD monitors, or Portable LED lights that can accept DC in (like the or ). Unfortunately my 900 LED lights require 14V DC to be at it's 'Brightest' setting, but these little 12V DC batteries will power them up as well. Definitely not a bad price, and I have a few more on order. Trust me, i'm still putting them through the ringer. You can find them .

  • The votlage regulator on the Arduino can accept a maximum input voltage of 20VDC – This is well above the typicall voltage of a fully charged lead acid battery (13.8VDC). As you can see below, we simply used a 2.5mm DC barrel plug soldered to a pair of aligator clips. They clip on to the battery terminals and the Arduino fires right up. An inline fuse on one or both leads would be a safe addition to this setup – the instantaneous (shorted) current from a 12VDC battery of this size is very high.
