Cheap Lipos from Hong Kong - False Economy?

[JezT]

Hi,

My son, Max, and I went racing 1/10 electric offroad at Hinckley on Saturday - 1st time racing; Other than our lack of driving ability!, our only major problem was with batteries - between us we have 5 nimhs (2 x 2200, 1 x 3600, 1 x 4600, 1 x 5100) and 1 battery charger.... It was really confusing timing which to use, which to charge etc. Decided we want to go Lipo - we are equipped for it, both running Exceed 70A speedos and 10.5 motors, charger can charge Lipos also.

Problem is I am on a very tight budget; Been looking at Lipos from Hong Kong on Ebay Example:

To equip ourselves with 4 batteries would come in at under £50 - Is this a false economy? Bearing in mind our driving abilities, is 30C too powerfull? Any advice on buying from the East or recommendations please.

Cheers,

Jez
