Large fixed-wing UAVs, mapping, surveying, inspection and other endurance platforms are key application directions when the complete aircraft is compatible with the pack's voltage, dimensions, installed mass and electrical capability.\u003c\/p\u003e\n\n\u003ch3 style=\"font-size:15px;font-weight:bold;margin:14px 0 8px;color:#000;\"\u003eIs the XT90 version more powerful than the XT60 version?\u003c\/h3\u003e\n\u003cp style=\"font-size:15px;line-height:1.75;margin:0 0 14px;color:#333;\"\u003eNo. Both versions use the same BAK 50D cells and 6S3P architecture.
