Thanks everyone, particularly kingarthur who fixed the problem with the gimprovements mod I was using.

I now have Lithium Ion Batteries!!!!

Should I notify the author of that mod?

Decided to try the shortcut and use the console to grant research of Battery 2 - it worked but still no Lithium Ion Batteries!!! They do not show up in any searches so looks like they do not exist!!!

I have checked some Youtube videos - as recently as Aug 2016, the tech tree did not include Science Pack 4 (purple) as a prerequisite for Lithium Ion Batteries 9only green, red and blue science was necessary).

Is there a way to change this back?

Thanks

thanks
