Low cost Yeah Racing Lipo

[VintageRacer]

I have been looking for a cheap stick pack for my Optima and found these that are about the same price as some more expensive NiMH packs.

Anyone have any experience of these?

Some eBayers are selling for much less direct from Hong Kong too (about £20 shipped!) which makes it very tempting.

I'd have to factor in the cost of a balancer and a cut-off but might still be worth it.
