Arrival of new batteries

Today I received also a new battery pack. The new Turnigy Lipos are 15C rated and weight a little more than the first ones (only 10C). Now I have 6 x 8000mAh 6s batteries. Next test will be conducted to compare the performace of each one. With all batteries I should have a autonomy of about 20min full power. The battery weight is 6kg and the housing motor 2kgs as before. Here a photo of the two battery types:
