ge power lipos???

hi all, i am needing some new lipos as i only have 2 2s lipos for my losi 8b at the moment.
since the pound is rubbish to the dollar at the moment it makes buying stuff outside the UK very expensive
so on ebay there are a few sellers selling these GE power 14.8v 25c 4000mah lipos and i was wondering if they would be any good for my losi 8b? and what the quality is like e.t.c

thanks richard
