In addition to conventional track power and TMCC, battery powered locos have been part of my operating scene for over 5 years. During this time I have never lost a PC board and when the systems I tested ran into motor current overload, they merely shut down. Installation and proper battery management are important factors for this mode. There is a substantial federally funded program to keep improving the performance and reliability of lithium batteries. I endorse the idea of a battery power forum topic.
