Specifications:
- Motor Current: ±300A max (±406A measurement range)
- Voltage: 60V – 168V (200V rated components, 40s Li-Ion max)
- Weight: ~180g with standard wiring
- Dimensions: 110 × 51.3 × 29.8mm
- Mounting: 7× M3 pattern
Electrical Features:
- GaN (Gallium Nitride) power stage — dramatically lower losses than silicon MOSFETs, 24ns dead time, zero reverse recovery — Why GaN?
- Integrated CANBus, IMU LSM6DSV32X
- Robust 2mm FR4 14-Layer 2OZ PCB
- Built-in ESP32-C3 running VESC Express — WiFi, Bluetooth, and LiSP scripting out of the box
- Phase shunt current sensing — ultra-low noise V0 & V7 sampling enables silent HFI sensorless operation. Accurate current measurement across the full duty cycle range, unlike low-side shunts that degrade at high duty
- Momentary button power control — auto shutdown on inactivity, low standby drain when off
- Power Connections: M5 crimping lugs (battery & motor)
- Signal Connections: JST GH locking connectors — CANBus, ADC, UART, PPM, Hall sensors, 5V/3.3V, SPI, Button, Encoder, Motor Temperature
- USB: Dual USB Type-C — one for STM32, one for ESP32-C3, both accessible via VESC-Tool
Motor Control:
- FOC, BLDC & DC: Compatible with sensorless, Hall sensor, encoder, or silent HFI (High Frequency Injection) — no sensor required, no audible noise.
- Control Flexibility: Current, duty cycle, or PID RPM control — adjustable limits for current, voltage, RPM, power, and regenerative braking via VESC Tool.
Custom Options Available
Custom G18 variants are available on request.
Voltage options:
100V version — EPC2361 GaN FETs, 3 in parallel
Typical effective RDS(on): ~0.25mΩ
150V version — EPC2305 GaN FETs, 3 in parallel
Typical effective RDS(on): ~0.73mΩ

We can also provide custom mounting plates depending on your build, heatsink, enclosure, or mounting requirements.
Contact us before ordering if you need a custom voltage version or mounting solution.
Note: When connecting the battery, use a precharge resistor to limit inrush current and prevent damage. Regenerative braking automatically reduces to 0A when the battery is full.

Been riding on the G18 esc for two months with a 32s pack and so far so good! Its thermals stayed clean, only went 47 degrees one time while my SF motor was overheating during a hot and technical event. The GaN mosfets seemed like the way to go compared to the concurrence. Moreover the new IMU is top notch and the board feels reactive and smooth.
For me it's the first 32s+ reliable controller after one year and a half spent with a Damocles sword above my head with a Thor400...
Will now build a 38s1p pack to go further with it but great job for a beta product!
I’ve been running the JetFleet G18 in a VESC-based Onewheel with a 40S (168V) battery pack, and so far it has been one of the most impressive controllers I’ve used.
Installation was straightforward thanks to the included GT mounting plate. It fit perfectly in the GT enclosure and made for a very clean, seamless install without any custom fabrication.
What stands out the most is how incredibly quiet this controller is. I’ve tested several VESC controllers over the years, and the G18 drives my motor noticeably quieter than any of them. The motor is essentially silent in operation. I suspect the excellent current sensing implementation is a major contributor here, as the controller’s sampling quality appears exceptional. The result is extremely smooth and refined motor control. The G18 uses a GaN power stage and is designed around low-noise current sensing and high-speed switching, which aligns well with what I’m experiencing in real-world use.
Thermal performance has also been outstanding. During normal riding, controller temperatures typically stay only 12–18°C above ambient. The GaN FETs are clearly doing their job here, delivering very low losses and excellent efficiency even at high voltage. JetFleet specifically highlights the low-loss GaN power stage as a core design feature, and my experience backs that up.
Another highlight is the IMU performance. Running at 3840 Hz, it produces a very stable ride feel with no observable nose hunting or oscillation. The board feels locked in and predictable, even when pushing harder.
The integrated ESP32-C3, VESC Express support, and high-voltage capability up to 168V make it a very compelling platform for advanced builds. The hardware is clearly designed with high-performance applications in mind.
Finally, customer support has been excellent. The JetFleet team has been responsive and helpful whenever I’ve had installation or configuration questions, which is especially valuable when working with cutting-edge hardware.
Overall, the G18 has exceeded my expectations. If you’re building a high-voltage VESC platform and want exceptional efficiency, outstanding thermals, near-silent motor operation, and great support, it’s an easy recommendation.
