Oh so adorable, this is the tiniest little lipo charger, so handy you can keep it any project box! Its also easy to use.

SF-PRT-10473

This charger accurately balances and charges Lithium Polymer, LiFe (A123), NiCd and NiMH batteries. It will handle LiPo/LiFe up to 6S and NiMH/NiCd up to 15S and shows individual cell voltage during charge with realtime updates throughout the charge cycle.

I found these high-quality battery clips. They're molded plastic so they wont tear like cheap clips, and they cover the battery terminals to prevent shorts.

AF-368

If you need to connect a DC power wall wart to a board that doesn't have a DC jack - this adapter will come in very handy! There is a 2.1mm DC jack on one end, and a screw terminal block on the other. The terminals are labeled with positive/negative assuming a positive-tip con...

Need a big battery for your project? This lithium ion pack is made of 2 balanced 2200mAh cells for a total of 4400mA capacity! The cells are connected in parallel and spot-welded to a protection circuit that provides over-voltage, under-voltage and over-current protection.

SF-PRT-09518

This simple cable has so many uses! Plug the 9 volt battery clip onto a standard 9V battery and connect the other end to anything with a 5.5x2.1mm, center-positive barrel jack.
