Hi folks has. Anyone managed to use a lipo batterie for powering a g scale loco,I was planning to tow one in a water tanker to power my shay with rc..

Yes.
Though I would not use a 'polymer' battery..
You can get Lithium batteries in either a 'can' (look like a standard cell) or a 'plastic bag' (a true polymer battery).
Obviously, a standard cell is more robust than the softer, flexible type.
If this is your first-time with Lithium-based batteries:
Buy a made-up pack, with protection.
Buy batteries, and charger, from the same supplier. - Ask the question about the two being compatible with each other.
Never take a battery pack apart, and do make sure you do not over-discharge them (one reason for getting a protected pack).
Lithium 'cells' give a nominal 3.77V per cell, so you will only need 3-4 of these for your Shay.
They also have a higher charge-density than NiMH cells, so you can get more out of them.

Yes, I've used the Ansmann Lith-Ion packs (with built-in protection boards for safety) in both of my wireless-DCC loco conversions - in both cases 14.8volt packs, a 4S2P (8 cell) 5.2 Amp/hour pack in the 2095 BoBo, and a smaller 4S1P (4 cell) 2.6 Ah pack in the Saxon IVk:
Building the Multi-Power Loco.... - G Scale Central
Today, I managed to put in a little time on my Multi-Power Loco project - the idea of which is to take an LGB track-power loco (an OBB 2095 "Whizzy Cranks", as it has a nice boxy body with plenty of room for added internal gubbins) and turn it in to a "touring" loco that I can take, and run...
Multi-Power Loco Mark II.... this time it's steam..... - G Scale Central
Having had success with my first "Multi-Power" loco project using an LGB 2095 Austrian BoBo Diesel, as described here: https://www.gscalecentral.net/threads/building-the-multi-power-loco.309298/ I've now made a start on the second project, which is putting a similar setup into an LGB Saxon Meyer...
Battery packs (and charger) purchased from Rapid, though they are available from other suppliers such as CPC Farnell.

Phil posted just as I was typing mine, agree with all that he has said. A decent quality industrial Lith-Ion battery pack with internal protection and a matching charger is, in my opinion, the way to go.

then choose "Ansmann" in the "brand" menu.

I suppose it depends on how confident you feel with a soldering iron and having a working knowledge of basic electronics. I've been soldering together my own li-ion packs for around five years now. I always include a protection board and a balance charge socket. I tend to use 18650 can type cells as they are the most prevalent but I buy them from a reputable supplier such as Ecolux. They can be bought more cheaply on eBay, but I have found it's a false economy.
