ESCs & Power Systems

Electronic speed controllers, power distribution boards and power modules for industrial UAV powertrains — sourced factory-direct in Shenzhen, matched to the motors they will drive, and documented lot by lot.

Paired Motor–ESC Sets Up to 18S-Class Systems Trial Orders Welcome

The Line

The electrical spine of the aircraft.
Three product families, one power path.

Electronic Speed Controllers

Industrial-grade controllers for UAV powertrains — from agile multirotor classes to high-current units for heavy-lift platforms. Supplied as standalone units or as matched motor–ESC sets, quoted against your platform's real load profile.

Power Distribution Boards

Distribution boards specified to the platform's current budget, routing pack power cleanly across the airframe. Sourced from the same vetted network of Tier-1 OEM factories as our propulsion lines.

Power Modules

Regulated power modules for flight controllers and avionics rails — stable voltage where the aircraft can least afford noise, specified alongside the flight-controller stack they will feed.

Specifications

Representative specification ranges.
Confirmed line by line at quotation.

Parameter	Representative range	Notes
Current class	Industrial ratings, up to high-current classes for heavy-lift platforms	Headroom checked against the motor's load profile, not just the label rating
Voltage class	Up to 18S-class systems	Matched to pack architecture and motor specification
Control protocols	Industry-standard control inputs	Compatibility confirmed against your flight-controller stack per RFQ
Integration	Paired motor–ESC sets available	Pairs verified as a unit before shipment approval
Firmware	Factory configurations as standard	Tuning support available through our engineering desk

Ranges shown are representative of the lines we trade, not a stock list. Every quotation is confirmed line by line against the manufacturer's current specification before we commit.

ESC–Motor Matching

The match is the product.
Reliability lives in the pairing.

On paper, an ESC is a component. In the airframe, it is half of a system. Current headroom, thermal margin and firmware behaviour all interact with the motor being driven — and a powertrain is only as dependable as the pairing decision behind it.

That is why we quote ESCs alongside the motors they will drive — including pairings for X13-class heavy-lift propulsion — rather than as line items in isolation.

Engineering & OEM support →

Current and voltage headroom checked against the motor's true load profile before the pair is quoted.
Thermal and mounting constraints reviewed against the airframe, not assessed from the datasheet alone.
Paired sets verified as a unit — so what arrives is a powertrain, not two boxes.
Delivered firmware configuration recorded, so repeat orders behave like the first one.

This judgment is earned in-house: our affiliated brand Lthunder engineers its own ESCs and flight controllers, and that bench work informs every pairing we quote.

Quality Control

Documented before it flies.
Every lot, every time.

Incoming QC

Units checked on arrival from the factory — visual, marking and authenticity checks against the purchase specification.

Pair Verification

Matched motor–ESC sets are verified as a unit before they are approved for packing and shipment.

Pre-Shipment Inspection

A documented inspection for every lot we ship, with records available to the buyer on request.

Documentation

Every shipment travels with structured, verifiable trade documents tied to the order it fulfils.

Questions

Asked before ordering.
Answered plainly.

Yes. Send the motor model or specification sheet with your RFQ. Our engineering desk pairs an appropriate controller, confirms current and voltage headroom against your platform's load profile, and can supply the pairing as a verified motor–ESC set.

Units ship in factory configuration by default. Where a platform needs specific settings, our engineering desk provides tuning support and records the delivered configuration — so repeat orders arrive set up identically to the first.
