Lipo battery choice

[Rcrcrus]

Hi all can any one share some infomation on lipos. I.ve seen some on ebay that are 2cell 7.4v 5000mah 30c. I would be using them in a losi 8t with a mamba monster combo. I'm going to be runing 2 packs. Now theas packs are cheap but are they worth the packaging. What i beleive is a lipo is a lipo they all got the same stuff inside. it's like buying a telly the inside is the same but the out side is not. Can anybody let me kow what they think of theas packs for £22.99. Cheers
