Here is a total scale flight of KDS Innova 700E without any 3D to test batteries from Vision battery Shenzhen. We flew on full positive pitch giving motor full load all the time for 5 minutes to 6 minutes time and pushed the batteries to their low cut off voltage limit. These are 6S 4000mAh packs from Vision and they impressed me with their performance on a big machines and a hot day giving juice to a motor operating on full load.
