I have to agree with the you get what you pay for attitude. I had a buddy of mine get me some 4 cell 4000 ma Lipos when he ordered from Hobby KIng. I just had bought a set of them from my local hobby shop a month or so before for $25.00 more than Hobby King. Giving credit where credit is due, they arrived within a week. Then the problem became apparent. Both batteries were bad and would not take a charge and the cells were all over the chart as far as voltage goes. One of them started to puff up while charging. As they say, the batteries went to the salt water and I learned a lesson....Cheaper is not always better.....
