I have an AristoCraft FA that I had converted to run on track power or NiCads with the onboard train Engineer so many moons ago. I had 15 “sub-C” cells in that thing but they no longer take a charge.
I want to replace them with 14.8V of Li-ion so that I can run the track cleaner around. I don’t need a great deal of speed for that operation and 14.8 volts should be more than enough.
It is easy enough to calculate the battery life from the amp-hours, but what are people using (e.g., 5,200 mAH) and getting (e.g., 3 hr of actual running) in real life?
