Going to be R/C a aristo 2-8-2 that will be pulling 7 aristo heavy weight cars, I see where controls are offered in both 5 and 10 amp also batteries that are 14.8 and 18.5 and was wondering onn thoughts for this application, Bill

Battery choice I would go for;

The higher voltage to get a fast top end speed

The largest capacity (mAHr) to increase run time.

Basic rule of thumb I use for my battery choices for a small industrial loco a lower voltage will do but for larger “mainline” locos a higher voltage is the choice.

Controller rating;

Go for higher rating as it will not be running near its limits (not knowing current draw of motor)

Hope this helps

I second GAPs suggestions. 18.5V would be preferable for an Aristocraft loco rated up to 20V. Pulling 7 heavyweights (!) is quite a load and it may be drawing 2 amps or more, so a 4400mah battery or similar would be desirable (=4.4 amps for 1 hour).

I put a complete Aristo Train Engineer, the trackside one, in the tender of an Aristo Pacific many moons ago, and it worked fine.

Make sure you use thick wires, not the skinny ones. (18 gauge or larger.)
