I personally have 12 lipos purchased from hobbyking as well as several friends who have "shared" an order to save $$ so far over 25 lipos all Turnigy but different mah and C ratings.
NOT A SINGLE FAILURE...... we all race weekly at a local track and run them in brushless vehicles so they are not babied. I run mine in a brushless Emaxx, E-Revo and Slash 4x4 so the get used.
I expected to have issues and always ordered more than I needed "just in case" heck at that price who cares and so far have been very pleased. My local hobbyshop also purchases them and re-labels them for re-sale. I would bet over 50% of the lipos at my local track came from Hobbyking.
Sorry you had a bad experience....but many LHS will not warranty lipos anyway. You have to deal with the manufacturere on the battery wty.
Sorry again...... but Hobbyking will continue to be where I get my lipos....hopefully my luck will hold out.
