Capacity becomes flight time only after you subtract unusable energy, reserve and the mass penalty the pack adds.<\/p>\n<ol>\n<li>Take hover power at target all-up weight from a thrust table or flight log, not from the motor&#8217;s maximum rating.<\/li>\n<li>Set usable energy at 80% of nameplate if the pack has to survive hundreds of cycles.<\/li>\n<li>Flight time in minutes = usable Wh \/ hover W x 60.<\/li>\n<li>Add 15-20% for climb, wind and the go-around you will eventually need.<\/li>\n<li>Check peak current: max thrust current per motor x motor count must stay inside 5C, and sustained climb inside 3C.<\/li>\n<\/ol>\n<p>On this pack, 3,907 usable Wh gives about 29 minutes at 8 kW of hover power and about 39 minutes at 6 kW. Every extra kilowatt of hover power takes 5-6 minutes off the same pack.<\/p>\n<p>Then check mass share. An 18.12 kg pack inside a 25 kg airframe is 72% of the aircraft, leaving under 7 kg for motors, frame, avionics and payload. At that point the honest answer is usually a lighter pack plus a second one in rotation.

At 269 Wh\/kg pack level a semi-solid pack carries more watt-hours per kilogram than a typical high-rate LiPo, so it wins on flight time and cycle cost, and loses wherever peak current dominates.<\/p>\n<p><strong>Can a semi-solid pack replace a LiPo on an existing airframe?<\/strong> Usually not without rework. The pack is heavier per unit volume, the window runs to 4.3 V, and the tray has to clear ribbon balance leads and bullet main leads. Check peak current against 5C and confirm charger end voltage first.<\/p>\n<p><strong>What C-rate do I need for a long-endurance multirotor?<\/strong> Sustained climb current plus margin, not burst. Size continuous draw near 3C and keep short peaks inside 5C on a semi-solid pack. High-rate LiPo tolerates far more, which is why transient-heavy profiles still default to it.<\/p>\n<p><strong>How many cycles should I expect from a semi-solid pack?<\/strong> The label states 600 cycles, assuming disciplined storage voltage, moderate charge current and no deep discharges. Treat 600 as an upper bound tied to duty cycle, against 200-300 cycles for high-rate LiPo.<\/p>\n<p><strong>Does a higher energy density pack always increase flight time?<\/strong> No. Flight time is usable watt-hours divided by hover power, and a heavier pack raises hover power. Above roughly 60% pack mass share the extra energy is offset by the structure and thrust needed to carry it.<\/p>\n<p><strong>What information do I need to quote a long-endurance pack?<\/strong> Hover power or all-up weight, target endurance, motor count and KV, maximum thrust current per motor, and pack count per aircraft. With those five inputs we confirm voltage class, C-rate headroom and configuration before quoting MOQ and lead time.<\/p>\n<h2>Bottom line<\/h2>\n<p>Choose semi-solid Li-ion when flight time per sortie and cycles per pack drive your cost model, and high-rate LiPo when peak current and crash economics do. Convert the label into currents, mass and minutes before you sign a build sheet \u2014 this argument is settled by arithmetic, not by the word on the casing.<\/p>\n<p><strong>REACHSKY Engineering Team<\/strong> \u2014 propulsion and battery selection support from Changsha, Hunan.
