It is ideal for heavy-lift FPV drones, high-speed copters, industrial drones, heavy robotic platforms, mobile stations, and power modules.<\/p>\n<p data-path-to-node=\"6\">The <strong>6S3P<\/strong> configuration (6 cells in series, 3 in parallel) provides a nominal voltage of <strong>21.6V<\/strong> and a capacity of <strong>15000mAh<\/strong>. This FPV Li-ion battery features a heat-resistant shrink wrap and is fully ready for use out of the box thanks to factory cell balancing.<\/p>\n<p data-path-to-node=\"7\">This 6S Li-ion battery is designed to power ultra-high-draw unmanned systems: 18\u201321 inch quadcopters, hexacopters, octocopters with a high takeoff weight, high-speed drones, and heavy UGVs. It delivers high discharge rates without voltage sag during peak startup loads and high initial torque demands.<\/p>\n<p data-path-to-node=\"8\">The use of an industrial-grade connector on the 6S3P batteries reduces the power line contact resistance to 0.15\u20130.20 mOhm, which is nearly half that of an XT90 connector. The connector can withstand peak current loads of up to <strong>330A<\/strong>, allowing you to utilize the full power of the high-discharge <a href=\"https:\/\/ft.systems\/lithium-ion-battery-inr-21700-5000-mah\/\">FT INR 21700 cells<\/a>.<\/p>\n<p data-path-to-node=\"9\"><b data-path-to-node=\"9\" data-index-in-node=\"0\">Key Advantages:<\/b><\/p>\n<ul data-path-to-node=\"10\">\n<li>\n<p data-path-to-node=\"10,0,0\">6S3P packs are perfect for powering power-hungry UAVs;<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,1,0\">the XT150 connector ensures stable operation at high currents with minimal contact resistance losses;<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"10,2,0\">soft-pack design with protective electrical insulation cardboard and heat-shrink wrap.<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A high-capacity 6S3P 15000mAh 21.6V XT150 Li-ion battery for heavy-lift copters, high-speed drones, heavy UGVs, and power-hungry stations.
