Clem, all my steamers have the battery in the tender, diesels are inside on the chassis. The 9.6v battery I use is 1.1"x1.1"x4.5". I've never tried a smaller battery (size or voltage). I run at fairly slow speeds (usually under 60smph) and a lesser volt battery may work just as well, I don't know for sure. The 11.1 LiPo batteries are a bit larger and I use a 12v battery in the Williams/Samhongsa 4-8-4 and I believe one other. I go to All-Battery to determine which one will work, and usually find them on Amazon cheaper than what they are direct once shipping/tax is included. These batteries are good for several hundred if not 1,000 charges. I haven't had to replace one yet.
I wasn't sure how any of these would run with only a 9.6v battery, but they're just as fast as when they were under DCS/TMCC 18+ volts. I don't know what voltage actually gets to the motors using DCS/TMCC but I don't think it's over 12dc, but I could be wrong.
If you can follow an electrical schematic and do basic soldering you should be good to go. But there are a few places that will do the install for you.
