I have 2 Trinity certified 7700 HC 2s lipos for sale. These are team driver packs and they were well taken care of . Packs are in excellent condition but are not perfectly flat. I wouldn't consider them puffed but they are not absolutely flat. this is common on these packs as there is just to much material in the same size case. Just want to be honest so you are happy with what your buying. asking $70 each shipped or $130 for both
