The video is a tutorial that describes how to determine how long to safely discharge a rechargeable Lithium-ion battery, so that it is not ruined, when a low voltage cutoff circuit is NOT used. The process is described, and the two previously converted to Dead Rail operation locomotives are compared and used to provide examples.
My Webpage titled “A Journey Into HO Scale Model Railroading in the
21st Century” is where I’ve posted a lot more information on my foam board constructed, portable, Dead Rail demonstration layout. It also has information on the conversion of two Walthers' EMD GP15-1s for Dead Rail operation using LocoFi and lots of other useful information and concepts.
