I have one of the 6.8 Ah lipo batteries on order (if it actually gets here); http://www.ebay.com.au/itm/261192027140?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Ok I have an idea to charge it inside the steam tram motor.... using an isolated section of track run it onto said short length of track and as the motor block will have contact through the wheels and rather than the power running form the wheels to the motor have the juice running to the battery; apply power to the track and charge it up without having to invert the thing and plug it in. I would propose that a rectifier is inside the works somewhere to ensure that it is not polarity sensitive and this would also block current escaping back into the track. One problem I see is that the rectifier voltage drop may not provide enough volts to charge the battery and I may also need to "extend" the led indicator to let me see when the battery is charged..... Totally Heath Robinson I know but....
Thoughts from the floor?
Oh BTW this is an idea inspired from real life, this system was used in the 1890's in Bendigo with real battery trams, it was a total failure....
