Hi Gizzy
I have the Piko battery 'Clean Machine' and am wanting to 'RC' it with the Piko 34050 kit.
If you take out the weight plates from the sides that will give plenty of room for extra batteries.
The plates could be redistributed around the chassis. Or pieces of lead could be used (I have some lead flashing that I use for cutting out shaped pieces)
Have a look at my conversion where I stuffed 10 aaa’s in for a Fosworks setup. Admitedly I removed all the existing board and lights but could probably put lights in if I could be bothered.

Well I seem to have found the problem!

More by luck than design?

I charged up the Strikalite pack, which, as I mentioned, is not a tight fit in the battery space. (Oo-er Missus!)

I found that if I held the loco with the back of the cab facing down, the weight of the battery pack made better contact on the spring connectors, and the loco ran reliably. As soon as I put the loco on the flat, the loco would run intermittantly.

This seems to confirm my suspicion of a high current draw, due to the poor contact.

So the next step will be to fit the Piko battery holder, which fits snugly, once I get the replacement batteries delivered this week.

If necessary, I might fit a PP3 connector in place of the spring contacts, so that the battery holders click into place for a better contact!

Next job, is to advise Sandy at SGR....

Just out of interest, are the positive terminal caps shorter than a normal AA. The reason I ask is that I have encountered intermittent connectivity with certain makes of battery cells, which under examination were found to have short terminal caps and the 'shoulder of the battery was holding them just off the connection in the battery box. The negative battery box terminal were the spring type, so were fine, but the positive ones being a fixed plate were not adjustable. A small dob of solder sorted out the issue. (Worst offenders were IKEA AA & AAA rechargeables.)
Regards,
Paul.

Paul, my problem is not with the AAA cells per se but the battery holder/pack that the cells are fitted to.

They are fitted with a PP3 connector, but this connector butts upto spring connectors and these are where my problem is, especially with the Strikalite pack on the left....

Gizzy,
Chop the end off a washing up sponge, and stick that behind your Strikalite pack, before popping the grill back onto the loco.
OR,
Stick a thick piece of plastic /wood under the pack.. Long enough to use the original clip.

Good idea Phil!

Funnily enough, I've just cut up some hi density foam for another task, and I have a couple of off-cuts left over....

Yeah, I was going to suggest beefing up the spring contacts one way or another.

High density foam, which we use at work for tool trays JD.

Not like the water absorbent sponge you meant....
