Li-ion (cylindrical) offers good energy density and excellent cycle life inside a robust steel can. Semi-solid offers the highest energy density (350-400 Wh\/kg at cell level) and the safest chemistry, at a higher cost. Choose based on whether you prioritize current, endurance, or energy per kilogram.<\/div><\/div><\/div>\r\n <div class=\"faq-item\"><button class=\"faq-q\">Does a high-voltage (LiHV) battery really give longer flight time?<span class=\"plus\">+<\/span><\/button><div class=\"faq-a\"><div class=\"inner\">Yes. LiHV cells at 3.85-3.95V nominal (4.45V max charge) hold roughly 5-10% more usable energy than standard 3.7V cells at the same weight. The trade-off is a modest reduction in cycle life, plus the need for an HV-capable charger.

A heavy-lift drone that spikes to 400A with a 66Ah pack needs about 6C of continuous headroom. Under-spec the C-rating, and the pack sags under load.<\/div><\/div><\/div>\r\n <div class=\"faq-item\"><button class=\"faq-q\">What certifications does a drone battery need for export?<span class=\"plus\">+<\/span><\/button><div class=\"faq-a\"><div class=\"inner\">At minimum, UN38.3 for transport, plus IEC 61960\/62133 or UL 1642 for safety. CE marking covers the European market, and RoHS covers hazardous substances. Larger fleets increasingly expect IATF 16949 process certification.<\/div><\/div><\/div>\r\n <div class=\"faq-item\"><button class=\"faq-q\">How does the custom OEM process work?<span class=\"plus\">+<\/span><\/button><div class=\"faq-a\"><div class=\"inner\">You provide a mission profile and target specs; we engineer a pack to your form factor, voltage, capacity, BMS and connector, then build prototypes, validate them, and move to mass production. First samples typically arrive in weeks. See <a href=\"https:\/\/wesbattery.com\/zh\/custom-drone-battery-oem\/\" style=\"color:var(--accent-soft)\">custom drone battery OEM<\/a>.<\/div><\/div><\/div>\r\n <div class=\"faq-item\"><button class=\"faq-q\">Can I ship drone batteries by air?<span class=\"plus\">+<\/span><\/button><div class=\"faq-a\"><div class=\"inner\">Yes, under IATA dangerous-goods rules: cells must pass UN38.3, be declared correctly, and fall within state-of-charge (SoC) limits \u2014 commonly \u226430% for air cargo.
