Set them in that order, because each one constrains the next.<\/li>\n<li class=\"leading-7 \">The examples in this guide come from MAD packs listed in the catalog. Product labels and catalog wording may describe a pack as semi-solid; that wording should not be changed to solid-state without the manufacturer&#8217;s technical confirmation.<\/li>\n<li class=\"leading-7 \">C-rating does not add capacity. It only sets how much current a pack can deliver, so an undersized rating shows up as voltage sag, heat and a shorter service life.<\/li>\n<\/ul>\n<p class=\"my-3 first:mt-0 last:mb-0\">Drone battery selection is a three-variable decision, not a single specification. Start with the voltage required by the propulsion system, then compare usable energy, current capability, mass and charging limits for the actual mission. Pack voltage sets the motor KV band and the ESC voltage class. Capacity sets how long the aircraft stays up. C-rating sets how much current the pack can push before it sags. Work through all three against one real platform and you can lock a battery SKU with fewer returns.<\/p>\n<figure id=\"attachment_7767\" aria-describedby=\"caption-attachment-7767\" style=\"width: 1600px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-7767\" src=\"https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured.webp\" alt=\"MAD 12S 35000mAh drone battery, front label viewed straight on\" width=\"1600\" height=\"900\" srcset=\"https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured.webp 1600w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured-300x169.webp 300w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured-1024x576.webp 1024w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured-768x432.webp 768w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured-1536x864.webp 1536w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured-18x10.webp 18w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured-800x450.webp 800w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/01-drone-battery-selection-featured-600x338.webp 600w\" sizes=\"auto, (max-width: 1600px) 100vw, 1600px\" \/><figcaption id=\"caption-attachment-7767\" class=\"wp-caption-text\">The MAD 12S 35Ah pack, labelled 44.4V \/ 1,554Wh with 5C continuous and 10C peak discharge.<\/figcaption><\/figure>\n<h2 class=\"mt-8 mb-3 text-[1.25em] font-semibold tracking-tight text-foreground first:mt-0 dark:text-zinc-100\">Drone battery selection: voltage, capacity and C-rating<\/h2>\n<p class=\"my-3 first:mt-0 last:mb-0\">Voltage, capacity and C-rating are separate specifications that must be checked together. Changing one may force a different motor, ESC, connector, mass or charging requirement, but the values do not automatically change each other.<\/p>\n<p class=\"my-3 first:mt-0 last:mb-0\">Pack voltage is the series count times cell voltage. The MAD 12S pack carries a 44.4V label and the 24S pack 88.8V, both consistent with roughly 3.7V per cell nominal. Series count fixes two things at once: the KV band your motors should sit in, and the voltage class your ESC, wiring and connectors must tolerate.<\/p>\n<ul class=\"my-2 space-y-1.5 marker:text-muted-foreground\/60 dark:marker:text-zinc-500 pl-6\">\n<li class=\"leading-7 \"><strong class=\"font-semibold text-foreground dark:text-zinc-100\">Voltage (S)<\/strong>\u00a0\u2014 sets the motor KV band and the ESC voltage class.<\/li>\n<li class=\"leading-7 \"><strong class=\"font-semibold text-foreground dark:text-zinc-100\">Capacity (Ah)<\/strong>\u00a0\u2014 sets endurance: flight time at a given average current.<\/li>\n<li class=\"leading-7 \"><strong class=\"font-semibold text-foreground dark:text-zinc-100\">C-rating<\/strong>\u00a0\u2014 sets the continuous current ceiling and how much the pack heats under load.<\/li>\n<\/ul>\n<p class=\"my-3 first:mt-0 last:mb-0\">Capacity in amp-hours describes charge quantity. When pack voltages differ, compare nominal energy in watt-hours (V \u00d7 Ah) before using Ah to discuss endurance. Usable energy, aircraft mass, temperature and mission power still determine flight time in practice. At a fixed current draw, a 55 Ah pack runs longer than an 18 Ah pack of the same voltage. C-rating then sets the current ceiling, because pack current equals capacity multiplied by the C-rating. A 55 Ah pack and an 18 Ah pack at the same C-rating can deliver very different continuous currents.<\/p>\n<p class=\"my-3 first:mt-0 last:mb-0\">Get the order wrong and the mismatch surfaces later. Too much KV on a high-voltage pack pulls current the wiring was never sized for. A high C-rating on a low-capacity pack still leaves you with a short flight. A big-capacity pack on an airframe that needs agility adds mass you fly with on every mission.<\/p>\n<figure id=\"attachment_7768\" aria-describedby=\"caption-attachment-7768\" style=\"width: 1672px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-7768\" src=\"https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix.png\" alt=\"Voltage, capacity and C-rating selection matrix for MAD drone batteries\" width=\"1672\" height=\"941\" srcset=\"https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix.png 1672w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix-300x169.png 300w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix-1024x576.png 1024w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix-768x432.png 768w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix-1536x864.png 1536w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix-18x10.png 18w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix-800x450.png 800w, https:\/\/reachsky.co\/wp-content\/uploads\/2026\/10\/02-drone-battery-selection-selection-matrix-600x338.png 600w\" sizes=\"auto, (max-width: 1672px) 100vw, 1672px\" \/><figcaption id=\"caption-attachment-7768\" class=\"wp-caption-text\">How series count, capacity range and C-rating map together across the MAD battery line.<\/figcaption><\/figure>\n<h3 class=\"mt-6 mb-2 text-[1.05em] font-semibold text-foreground first:mt-0 dark:text-zinc-100\">Drone battery selection: what C-rating do you need?<\/h3>\n<p class=\"my-3 first:mt-0 last:mb-0\">Size the C-rating to your worst-case continuous current, not to a peak burst.

For the same motor, increasing applied voltage raises the approximate no-load speed; it does not change the motor&#8217;s KV rating. Loaded speed depends on the propeller, current limit and operating point, so choose the KV band from the complete motor\u2013propeller test data. Push too much KV onto a high-voltage pack and current and heat climb. Run too little KV on a light pack and you leave thrust on the table and invite over-propping.<\/p>\n<p class=\"my-3 first:mt-0 last:mb-0\">That is why we size voltage first. Once the pack voltage is fixed, the KV band is a narrow window, and the ESC class and wiring follow from it.

Fix voltage first, then pick capacity and C-rating.<\/p>\n<h3 class=\"mt-6 mb-2 text-[1.05em] font-semibold text-foreground first:mt-0 dark:text-zinc-100\">What C-rating does a drone battery actually need?<\/h3>\n<p class=\"my-3 first:mt-0 last:mb-0\">Match the C-rating to your worst-case continuous current, not to peak bursts. Multiply capacity by the C-rating to get the pack&#8217;s current ceiling, then keep your mission average well below it. A pack that is always run near its limit runs hotter and ages faster, so leave headroom.<\/p>\n<h3 class=\"mt-6 mb-2 text-[1.05em] font-semibold text-foreground first:mt-0 dark:text-zinc-100\">Does a higher cell count always mean longer flight time?<\/h3>\n<p class=\"my-3 first:mt-0 last:mb-0\">No. Cell count sets voltage, not energy. Flight time depends on capacity and total current draw, so a high-voltage pack with modest capacity can fly shorter than a lower-voltage pack with more amp-hours. Size voltage for the motor band and capacity for endurance, and treat them as separate decisions.<\/p>\n<h3 class=\"mt-6 mb-2 text-[1.05em] font-semibold text-foreground first:mt-0 dark:text-zinc-100\">What capacity range fits an agricultural spraying drone?<\/h3>\n<p class=\"my-3 first:mt-0 last:mb-0\">The catalog examples include 6S and 12S packs used in agricultural applications. Confirm the current SKU, dimensions, weight, connector, charge limit and duty cycle before treating a range as suitable for a specific aircraft. Pick the smallest capacity that covers your tank-to-tank mission time at average current; extra capacity adds weight you carry on every flight. Confirm the choice against your duty cycle.<\/p>\n<h3 class=\"mt-6 mb-2 text-[1.05em] font-semibold text-foreground first:mt-0 dark:text-zinc-100\">Can I mix different series counts in one drone fleet?<\/h3>\n<p class=\"my-3 first:mt-0 last:mb-0\">You can, but keep the KV bands and ESC voltage classes separate. A 6S airframe and a 12S airframe need different motors and ESCs, so spares do not cross over. Standardise where maintenance cost matters, and keep mixed fleets only where the missions are genuinely different.<\/p>\n<h3 class=\"mt-6 mb-2 text-[1.05em] font-semibold text-foreground first:mt-0 dark:text-zinc-100\">What is the MOQ for MAD catalog battery packs?<\/h3>\n<p class=\"my-3 first:mt-0 last:mb-0\">Samples start at one piece through the catalog; there is no hard batch floor. Volume MOQ depends on the SKU, the marking method and the packaging you need, so it is confirmed per project. The MAD 12S 35Ah battery quotes volume pricing from 50 pcs.<\/p>\n<h3 class=\"mt-6 mb-2 text-[1.05em] font-semibold text-foreground first:mt-0 dark:text-zinc-100\">Which certifications come with your drone batteries?<\/h3>\n<p class=\"my-3 first:mt-0 last:mb-0\">REACHSKY works to an ISO 9001 quality system with RoHS and REACH aligned processes, and documents are provided on request. Certification scope depends on the SKU and the destination market, so confirm requirements in the quote. We only state certifications the specific part actually holds.<\/p>\n<h2 class=\"mt-8 mb-3 text-[1.25em] font-semibold tracking-tight text-foreground first:mt-0 dark:text-zinc-100\">Conclusion<\/h2>\n<p>For the next step, read our <a href=\"https:\/\/reachsky.co\/uncategorized\/battery-charger-selection-1-14s-vs-12-24s.html\">battery charger selection guide<\/a> and check the pack chemistry, supported cell count, charge-current limit and connector arrangement before choosing a charger.<\/p>\n<p class=\"my-3 first:mt-0 last:mb-0\">Voltage, capacity and C-rating are one decision made in three steps. Pick the series count that matches your motor KV band, set capacity to cover your worst-case mission time, then leave C-rating headroom above your continuous current. Done in that order, battery selection stops being a guessing game and becomes a specification.<\/p>\n<p class=\"my-3 first:mt-0 last:mb-0\">If you are sizing packs for a distributor range, a fleet or an OEM program, send us the airframe weight, duty cycle and target ship window.
