The 6350mAh and 12700mAh packs use the more energy-focused 65E platform for applications where capacity and endurance take higher priority.\u003c\/p\u003e\n\n\u003cp class=\"collapsible\"\u003eCompact 4S1P batteries are particularly relevant to weight-sensitive long-range aircraft, while 4S2P packs provide substantially more stored energy and load sharing for larger FPV wings, fixed-wing aircraft and UAVs.
