The 8S Sourcing Landscape

Because 12S (dual 6S) has dominated standard 700-class helicopter setups for over a decade, finding ready-made 8S (29.6V standard / 30.4V High Voltage) packs off the shelf can be a challenge. However, specialty manufacturers and select performance brands continue to stock them—and several custom pack builders offer tailored solutions for pilots looking to drop dead weight from their airframes.

Below is the complete manufacturer and sourcing directory for 8S packs, detailing available capacities, pricing, direct links, and real-world pilot feedback.

    Custom Pack Builders (OEM / ODM / Local Build) Custom cell selection (e.g., Tenpower 21700 or custom pouch configurations tailored to mAh requirements) Varies by cell grade & configuration Yattox / Grepow Custom Many industrial pack assemblers and specialty hobby shops will build 8S packs per customer request using specific discharge leads, soft/hard cases, and custom dimensions. Ideal for exact CG balancing.
    Sourcing Tip for Custom Builds: If you cannot find the exact dimensions or connector configuration you need from off-the-shelf suppliers, reaching out to custom lithium assemblers (such as Grepow or Yattox) allows you to specify exact discharge plugs (XT90, EC5, QS8), wire gauges, and form factors to match your airframe's battery tray perfectly.

    Why Source Dedicated 8S Packs?

    Instead of wrestling with two separate 4S or 6S packs in series—which introduces extra balance leads, unnecessary shrink wrap, and redundant solder joints—running a dedicated single 8S pack (or a clean 4S+4S hard-wired series harness) cuts down resistance, simplifies field charging, and shaves critical grams off your aircraft.
