Battery MX Course Sample

I have been requested to create some system-specific training. This is one of the videos I created for the online course. The battery maintenance subject was created for the NCATT AET but I find it was useful for those preparing for the Airframe and Powerplant certificate written test. For more information on the Battery maintenance course:

I am always looking for suggestions for short system explanations.
