Having previously converted only steam locomotives to battery power (battery and receiver inside tender),

does anyone have tips on how to find enough space to convert a diesel without using a following box car? 

Thanks

Rick

Finding space for the Rx should be relatively easy, it is the battery that is the problem.

There is a wide variation of 'spare' space depending on the model and scale.

I only have experience of UK prototypes in 00 scale,
and the available space varies from almost all space in my Lima diesels,
to modern Bachmanns which are stuffed with chassis metal to improve adhesion.

One advantage of Li-Po batteries,
is that you can have multiple small capacity cells scattered throughout the chassis,
connected in parallel giving in effect a larger capacity single cell.

Thanks, Dave


I should have also mentioned that I am working in HO scale.

I have watched a couple of YouTube videos (there aren't that many out there that show actual installation),
that show the Li-Po battery installed in the fuel tank (in the case of a model with a large enough fuel tank).

There is room for the Receiver to be installed flat on top of the motor.

Certainly, in any unit manufactured as a DCC product, the DCC receiver can be removed and replaced by the Micron receiver.

I have used 2 cell Li-Po (rather than 3 cell) batteries and no Pololu power boost with satisfactory results in all of my conversions so far.
I would therefore be hoping that the 2 cell would function well in a diesel locomotive as well.  
It's really just a case of purchasing HO units that have a large fuel tank I suppose.
But I was hoping to use early generation switching engines.

Thanks


Rick

Howdy Rick, a good friend of mine operates a large HO modern diesel powered layout following the Missouri Pacific RR.
He has a GP7 lash-up with one powered (Athearn) and the other is a dummy full of r/c board and 1600MAH 2 cell battery.
These are coupled together with a drawbar so they always run together. Maybe this would be of interest.

Woodie

I have managed to dig out an HO Athearn GP7,
which I converted by removing the decoder,
and fixing a DT Rx62 and nano-tech 300mAh 2s battery to the top of the hood with Blutac (plastic putty).

The battery measures 44mmx15mmx12mm.
I can’t say how long it would run because it hasn’t been tested.

But I have a UK outline 0-6-0 pannier tank, where a 48mmx28mmx10mm 450mAh 2s battery will squeeze inside the tanks,
and is shallow enough to clear the motor, with the Rx62 fixed beneath the cab roof,
which has run for 4 hours non-stop and was removed before the battery had expired.
 
On a pro rata basis I would expect the better part of 3 hours.

The photos are not terribly good,
but served as a learning curve for downsizing and uploading,
although I now need to crack why my browser does not support getting them from the gallery to the text!

I too had difficulty in getting images from the gallery into the text.
 

I use Windows-10 and found that if you open 2 copies of Freerails in separate tabs,

you can use the Gallery in one tab, and handle the text in the other,

so you can copy from one tab to the other.

Thanks, Dave


That's what I did, but just tried again to complete an earlier post with the same image,

and it's now too large!

I use a free program called IrfanView for basic image changes,

it does a lot more than that though.

I think my problem was finding out what happened if the Browse button was used,

and I picked up the original picture and not the revised one in the Gallery.

Tried to install Irfan View earlier this afternoon without success.

Good job, Geoff. Thanks for the photos.

I wasn't sure I could shoehorn a 2 cell Li-Po plus a receiver into a diesel.


I currently use 2 cell Li-Pos with great success in my steam locomotive conversions to battery powered.

My grandchildren have asked to run a diesel on my unfinished layout.  

I'm just trying to convert three units to run when they're over at my place.


Thanks


Rick
