probably I will buy a pack of one of this manufacturers for compare with my nanotech/a-spec batterys ....... I dont put the nanotech/a-spec in the list because I verified are a awesome lipos and works great (I have 15 packs)
¿opinions? 
I like Promatch. Reasonably priced and good quality.
Gens Ace is
garbage, especially for 8th scale racing. When my current crop of Gens Ace dies, which I'm sure wont be long, I will be done with them.
Thunder Power is high quality, but pricey. However, if you get a good one, they will last a long long time.
