GIFs of the paper copies of the schematics I received with my Balancer kit (quite legible and small for fast downloading; when printing from Windows, make sure to select the 'fit to page' printer option, otherwise they tend to print off huge):
PDFs of the original ORCAD schematic files (prettier, but much larger; good for ability to zoom in and read any fine print that you couldn't quite make out on the GIFs or your own paper copies):
