I'm starting a DCC conversion in a G-scale locomotive,
and would like the option to have 'Battery Powered Radio Control' in the future.
The system I want is the DRS1 MKIV, so I can use my existing DCC equipment,
but I haven't seen any of those in person yet.
How many wires do I need from the receiver in the tender to the decoder in the locomotive,
and how much space would be left for batteries ?
The usable inside dimensions of the tender are just over 3" x 2.25" x 1.25"
Also, what batteries might fit in that space,
that would be the optimal voltage and have long run-time ?

I run G-gauge locos with 'Battery Powered Radio Control', see here.
I decided there just wasn't enough room in the loco/tender,
so I put the electronics in 1 boxcar, and the batteries in a 2nd.
Long term plans are to use the MTH locos in DCC mode,
and use DCC++ to replace the rather large MTH Track Interface Unit.
Which would allow both track controller and batteries,
to fit in a single boxcar or passenger car.

Hello, Steve.
That doesn't sound promising,
since I like to run small switching locomotives, especially for operations.
Perhaps we're thinking of different systems.
I found the DRS1 receiver with built-in DCC booster for G gauge is 2.7" long and 1.2" wide.
They also sell a 3400mA 13.8v battery that is 2.75" x 1.46" x 1.46"
I'm guessing I should be able to easily fit a battery and receiver into my tender,
and get approximately 3 hours of run time.
Seeing how my loco's motor should only draw up to 1 Amp.

Eric,
My goal is to run large locos (eg. MTH Big Boy) with long consists.
I also am setting up a large outdoor track, about 750' at last measure.
I guestimate I will be drawing about 3 Amps for the loco,
plus a not insubstantial draw for the CPU and and Wi-Fi.
I am using Keeppower's 26650 5200mAh cell.
So maybe 1.5 hour run time.
Steve
