Jonathan, I think that's what's also in the Deltang boards, but I'd still like to be able to "see" how many minutes/hours I have on the battery.
These 2000Mah and 2200Mah NiMh and LiPo batteries I'm using have been pretty stable and consistent over 5 years. I thought I had a problem with one last month but it turned out to be a loose pin in the harness. I can expect 2.5 hrs run time but I rarely keep track of how long I run a train at any given time. I might run one for 5 minutes or run have a 2-3 hour operating session. I could tell Alexa to start/stop a timer but it would be easier if I had a simple display in the circuitry that would hold a memory and could be reset.
