Lion PowerCustom Drone Power Electronics
ESCs, battery packs and BMS, power distribution, tether power and wireless charging — designed around your airframe, payload and flight-time targets.
Where we fit on your drone
Every block in the diagram is a board we design for you — schematic, layout, firmware, prototypes and validation.
ESC / motor driver
Motor drives matched to your motors and propellers — efficient across the throttle range, quick to respond to the flight controller, and protected against stalls and overcurrent.
Motor Controller → 02Battery pack + BMS
Packs sized against your flight-time and weight budget, with cell monitoring, balancing and protection — and a state of charge you can trust before take-off.
Battery Management System → 03Power distribution & voltage converters
Light, efficient DC-DC rails for the flight controller, avionics, radios and payload, with low noise where sensors and radios need it.
Power Supply → 04Tether drone converter
The onboard converter that steps the tether's transmission voltage down to the drone's bus — power-dense and light, because every gram counts against payload.
Power Supply → 05Tether ground supply
The ground station that feeds the tether — converting mains or generator power to the transmission voltage, with the monitoring and protection continuous operation needs.
Power Supply → 06Wireless charger
A charging pad that tops the drone up whenever it lands — no connectors to wear out. Ground transmitter and onboard receiver are designed together for efficiency and tolerance to landing position.
Battery Charger → 07Something else on board?
Payload power, lighting, ground equipment — if it converts, stores or drives power on your drone, ask us.

Your team keeps its focus on the aircraft and the customer. We take the power electronics off your plate.
Your benefit
- Competitive advantage from the better performance of custom electronics
- Access to a highly experienced R&D team
- No risk associated with hiring a new workforce
- More time to focus on business development and the work that creates the most customer value
- Save time and money on EMC issues and certification
On every board
- Electromagnetic compatibility (EMC) design, so power electronics don't disturb GNSS, telemetry or video links
- Designed for CE / UL / IEC / FCC compliance, with pre-compliance testing
- Hardware and firmware from one source
- Prototyping and manufacturing — with support after hand-off
What clients say
Quoted feedback from past projects.
We were experiencing issue after issue with our motor controller modules and that's why we decided to get our own motor controller developed. Engineers at Lion Power made a really high-quality product which cut our field failure rate by 80%. Definitely recommend.
The stock motor drives that we used in our heat pump just didn't perform well enough and the price was ridiculous. We decided to invest in the development of our own drive so that we could own the design and manufacture it at a lower cost. Samo and his team proved more than adequate and they delivered the designs and validated prototypes ahead of schedule. This cost for our motor drive was reduced by 60%. Best investment we made.
Samo and his team took our project of developing the world's first USB-C charging for eBikes. Their expertise quickly identified improvements in our ideas and their commitment delivered the final product before the deadline. This allowed us to beat our competition as first to market.
We hired Samo because we needed scientific grade motor controllers for our robots that we just couldn't find elsewhere. Samo proved to be a reliable and trustworthy partner as he quickly and diligently responded to many requirement changes from our side during the project. Recommend.
We just completed our second project with Samo and are planning a third one. We went through a few 'low budget' freelancers before we found Samo and the results were 'low quality', like expected. Samo really turned things around for us. He took over the whole electronic system development and perfectly integrated with our mechanical department. The result was a high-power battery-operated LED light that passed all certifications with ease and is successfully selling.
I had an academic paper that described the high-voltage power supply necessary for our product. I reached out to more than 20 contractors and they all declined because they just didn't see the value in studying and learning something new. Samo gladly took up the challenge, reviewed multiple other academic papers, proved as a worthy discussion partner, improved upon the idea and finally built the power supply. It is now manufactured in multiple thousand units annually. Best contractor I had.
How we work
The same sequence, whether the deliverable is one board or a small production run.
Consult
Define the electrical and mechanical constraints — load, environment, volume, timeline.
Design
Topology, component selection, schematic and layout — reviewed against the real requirements.
Prototype
Bring-up, bench testing, and firmware to get a working unit in your hands fast.
Validate
Thermal, load, and reliability testing against the conditions the product will actually face.
Deliver
Production-ready documentation, firmware, and hand-off — or ongoing support, as needed.
Related work
The same building blocks a drone needs — motor drives, battery packs, BMS and chargers — from recent projects in other applications.
Synchronous Motor Control Card for Robotic Arm Actuators
Hardware and firmware control loops tuned to the client's actuator motors improved robotic-arm precision 30% — fewer defects, fewer mistakes in use.
Ultra-Compact Battery Pack for a Deep-Sea Light
A two-level cell configuration packed more capacity into a deep-sea light's tightly constrained battery volume — extending operating time 50% with no increase in product size.
Integrated Charger and BMS for a High-End Electric Road Bike
A compact, integrated charger and BMS let the frame get shaped around aerodynamics and rider comfort — not around bulky electronics.
