A production-grade quad ESC for Group 1 and Group 2 small unmanned aerial systems — 80A continuous per motor, 12S battery support, CAN and Ethernet connectivity, onboard orientation telemetry, and aux power rails for the rest of your stack. NDAA-compliant, built in the United States.
Complete technical specifications for the Lirith QuadDrive 80A (MPN: LR-QD80-A-1). Print-friendly — use your browser's print function to generate a clean spec sheet for evaluation reviews.
Every ESC survives its datasheet under a fan on a bench. Few survive a sealed airframe, a desert summer, and continuous throttle. We design for the second case — thick copper, deliberate thermal pathways, and low-RDS(on) FETs selected for automotive thermal stability rather than peak current alone.
Humidity, dust, and salt kill uncoated electronics in the field. Every Lirith ESC leaves the line under a conformal coat that covers the whole board, with masked keep-outs at connectors and test points. It's not a premium option. It's the baseline configuration.
Per-motor RPM, current, voltage, and FET temperature stream alongside onboard orientation data — giving autopilots and operators the full picture they need to detect a failing motor, flag anomalies in flight, and build the sustainment logs that matter.
QuadDrive 80A supports the full range of modern control protocols, including CAN bus and Ethernet — enabling integration into advanced GCS architectures and high-bandwidth autonomy stacks without protocol adapters or signal converters. If your airframe already speaks CAN or Ethernet, so does this ESC.
Onboard regulated rails — 3.3 V at 3 A, 5 V at 3 A, and 12 V at 1 A — feed flight controllers, companion computers, and peripherals directly from the main battery without a separate BEC or power distribution board. Fewer points of failure, cleaner airframe wiring.
Every component on the BOM is documented to its origin. Every board is assembled and tested domestically. Every shipment carries the paperwork your procurement team needs. Supply-chain compliance isn't a sales attachment — it's how the product is built.
Tactical quadcopters, FPV strike platforms, short-range ISR. The 80 A continuous rating covers high-thrust Group 1 motors with headroom for sustained operations at temperature.
Heavy-lift quadcopters, longer-endurance hexacopters, multirotor ISR and logistics platforms. 12S compatibility and 160 A peak support the highest-voltage, highest-thrust propulsion stacks in this weight class.
Every Lirith QuadDrive 80A ships with the documentation package DoD primes, federal agencies, and Blue UAS integrators already expect from their covered-component suppliers.
