Need Help with a DC-DC Buck Converter (LM2596) and LI-ION Batteries

I’m not sure what a cracked version is, but no it shouldn’t matter. You may have to update the parts library (it should happen automatically, but in some circumstances it doesn’t.) First try Help->check for updates to see what it says. If that doesn’t work you need to manually update the parts db. Note you need to find the Fritzing install directory on your system and load the github repository in to the Fritzing parts directory.

As to the batteries once you have dragged it in to a sketch (not in the parts bin!). Inspector will change some things. If what you want isn’t changeable then you (or more likely one of us) would need to make a custom part.

In Inspector (lower right circled in red) you can change amp hour ratings to some common values.
