Right off the bat, you need to describe what the heck you are doing, no offense.

1. lithium batteries cannot be combined in any way that the nominal voltage is 9 volts, they are 3.6 volts to 3.7 volts per cell.
2. unless you are trying to run without a motor controller, why are you picking 9 volts
3. assuming you want a control system, what system are you choosing.

The conversion is very simple, but more details are needed. Basically you ignore the wiring from the track pickups and connect to the motor. Lights are another story, again need your controller.

Forget smoke, uses as much power as the motor.

Measure it, it is NOT 9 volts and it is NOT 5.4 amp hours. it is 5.4 watt hours, big difference.

That is NOT a good battery to run the locomotives you have listed. Perhaps something like a Little Big Hauler, or a Piko 25 tonner.

love to see the arduino control system you will use... i can double check it for compatibility with your 11.1v packs.... (which will really be 10.8 to 11.1 nominal)
