For multirotors the average is close to hover power at take-off weight; for spraying drones it falls as the tank empties. The catch is that adding capacity adds weight, which raises hover power, so each extra watt-hour buys less flight time than the one before. Check peak power separately: climb, wind gusts and aggressive manoeuvres set the current the pack must deliver without sagging.<\/p><\/div><div class=\"hb-calc\"><div class=\"hd\">Worked example: 14S agricultural multirotor (illustrative numbers)<\/div><ol><li>Pack: 14S 30Ah.

Extra capacity adds weight, which raises hover power. Beyond a certain size each added watt-hour buys very little flight time, and payload capacity falls.<\/div><\/details><details><summary>What C-rate does my drone battery need?<\/summary><div class=\"a\">Enough for the climb and gust peaks with margin, not just hover. Log current in flight if you can; we size from the peak and the time it lasts.<\/div><\/details><details><summary>Lithium-ion or LiPo for industrial drones?<\/summary><div class=\"a\">Cylindrical lithium-ion cells usually give more endurance and cycle life for long flights; pouch LiPo cells handle higher bursts. Many heavy-lift drones use high-rate cylindrical cells as a balance.<\/div><\/details><details><summary>Can you match our existing battery&#8217;s shape and connector?<\/summary><div class=\"a\">Yes. Send the drawing or a sample, the connector and the BMS protocol your flight controller expects.<\/div><\/details><details><summary>How should drone batteries be stored between seasons?<\/summary><div class=\"a\">At partial charge, in a cool dry place, and checked periodically.
