I would like to be able to run my small portable layout "off the grid".

According to MTH the TIU can be powered by up to 24V DC...and it appears the PS2 & PS3 engines would be compatible.

So, I figure if I take (2) 12V gel cell batteries and hook 'em up in series, I can get that to work... wondering if anyone has done this, or a similar application of DCS on DC?

The alternative is to use a 12V AGM battery with a pure sine wave inverter to 120VAC then plug in a Lionel Powerbrick, as I usually do...seems like it would be easier but more inefficient! (going up to go down)

Your thoughts and experiences would be appreciated!

G Gauge guys do this.  Battery pack in one car feeds disassembled TIU in another, and output goes to ps-2 board.  So no reason you can't do it for a layout you want to be portable.  Just think about using a smaller external fuse maybe 6-10 amps.  Batteries can source high current if shorted, with no protection.  G

I've powered the TIU with DC laptop supplies, so there's no reason I can imagine that you can't run it on batteries.  Obviously, only the two fixed channels will work with DC.

Thanks guys,

MTH says all ps2/ps3 engines will work... GRJ, any issues or differences using DCS compared to running on AC?
