Battery Science

UAV Battery Chemistries — LiPo, Li-ion, HV-LiPo, Solid State.

The chemistry inside the pack drives flight time, payload, cycle life and safety margin. This page maps the chemistries GenX supplies onto the missions they fit — so procurement teams and platform engineers can pick the right starting point before specifying capacity, voltage or connector.

Chemistry Index

Five chemistries, mapped to mission.

Every chemistry has a different envelope on continuous discharge, energy density, cycle life and safety. Pick the one that matches the mission first; then size the pack against airframe weight, motor C-draw and the platform's connector / BMS constraints. Jump straight to a chemistry below, or scroll to compare them.

Chemistries

One chemistry per mission class.

Use these cards to anchor a chemistry choice before specifying capacity, voltage or pack form factor. Every chemistry maps to one or more mission landing pages with real GenX SKUs.

  • Chemistry 01

    LiPo (LiCoO₂)

    Lithium Polymer — the UAV workhorse

    Pouch-format lithium polymer cells optimised for high continuous discharge and burst current. The default chemistry for racing, agriculture spraying, heavy-lift and any mission that draws high transient loads from the pack.

    Best for

    Agriculture spraying, heavy-lift cargo, FPV and acrobatic platforms, multirotor ISR with high transient motor draw.

    Watch out for

    Lower cycle life than Li-ion. Sensitive to over-discharge and storage at full charge — requires disciplined storage voltage management for fleet operations.

  • Chemistry 02

    Li-ion

    Lithium-Ion (cylindrical) — endurance chemistry

    Cylindrical lithium-ion cells (18650 / 21700 class) configured into UAV packs for energy-density-led missions. Better Wh/kg than LiPo at the cost of continuous C-rate — the right pick when flight time matters more than peak power.

    Best for

    Mapping and survey, fixed-wing and VTOL endurance platforms, BVLOS corridors, long-loiter ISR, last-mile delivery.

    Watch out for

    Lower continuous discharge than LiPo — not suitable for high-rate spraying or aggressive cargo lift. Pack-level engineering matters more (cell matching, BMS, thermal).

  • Chemistry 03

    HV-LiPo

    High-Voltage LiPo — 4.35 V/cell

    High-voltage lithium polymer cells charged to 4.35 V/cell instead of the standard 4.20 V. Slightly higher energy density and pack voltage than conventional LiPo, picked by OEMs whose platforms can take advantage of the extra top-end.

    Best for

    Premium camera platforms, racing builds chasing peak power, and OEM programs that have qualified their motors and ESCs against HV-rated cells.

    Watch out for

    Reduced cycle life compared to standard LiPo and requires an HV-capable charger. Mixing HV and non-HV packs in a fleet creates charger-confusion risk.

  • Chemistry 04

    Semi-Solid State

    Polymer-gel electrolyte — safety + density

    A bridge chemistry that replaces conventional liquid electrolyte with a polymer-gel composite. Targets higher energy density and reduced thermal-runaway risk relative to standard LiPo while staying compatible with existing pack-assembly processes.

    Best for

    Programs that need a step-up in safety margin without waiting for full solid-state availability — defense ISR, inspection in sensitive environments, indoor industrial inspection.

    Watch out for

    Emerging chemistry. Availability, cost and cycle life vary across cell suppliers — qualification at OEM level is recommended before fleet rollout.

  • Chemistry 05

    Solid State

    Solid electrolyte — roadmap chemistry

    Cells using a fully solid electrolyte. The chemistry that the UAV industry is watching for the next major step-change in energy density, safety and cycle life. Currently early-commercial and roadmap-bound for most production drone platforms.

    Best for

    OEMs evaluating long-horizon platform programs that will benefit from a switch to solid-state when supply matures. Conversations welcome to scope qualification work and supply expectations.

    Watch out for

    Limited production volume and early-stage pricing. Not a drop-in replacement for current LiPo / Li-ion packs — pack engineering, charger and BMS need to be specified against the actual cell SKU.

FAQ

Chemistry procurement Q&A.

Specific question? Engineering usually responds within one working day. Talk to an engineer.

  • 01

    How do I pick a chemistry without knowing the exact pack spec?

    Start from the mission, not the chemistry. If the mission is high-rate (spraying, heavy-lift), default to LiPo. If the mission is endurance-led (mapping, BVLOS, long-loiter), default to Li-ion. HV-LiPo, Semi-Solid State and Solid State are platform-specific picks that should be qualified with engineering before fleet rollout.
  • 02

    Can I mix chemistries inside the same drone fleet?

    Yes, but each chemistry needs its own charger profile, storage discipline and inspection routine. Mixed-chemistry fleets work well when each chemistry is mapped to a specific airframe role; they go wrong when ground crews share chargers across chemistries without process controls in place.
  • 03

    Is Solid State production-ready for my UAV programme today?

    Generally not as a drop-in replacement. Solid State is shipping in limited commercial volumes and cell pricing reflects that. It is the right conversation for long-horizon OEM platform programmes that can absorb a qualification cycle. Talk to engineering before committing.
  • 04

    Does HV-LiPo just mean a bigger battery?

    No. HV-LiPo cells are chemically rated to charge to 4.35 V/cell instead of 4.20 V. That gives you a higher pack voltage and slightly more energy in the same form factor — but it also reduces cycle life and requires an HV-capable charger. Motors and ESCs should be qualified against the higher voltage before the platform switches.
  • 05

    What documentation do you provide on chemistry for procurement?

    Each pack family ships with UN38.3 transport test summaries, MSDS, BIS registration references where applicable, and CE/RoHS declarations. For export shipments we attach commercial invoice, packing list and dangerous-goods paperwork compatible with IATA Section II handling.
  • 06

    Can GenX engineer a custom pack around a specific chemistry?

    Yes. The custom program covers cell selection across LiPo, Li-ion, HV-LiPo and emerging chemistries, BMS integration, connector and harness work, mechanical form factor and labelling. Most engagements start with a fitment review against your airframe and motor spec.
