Raw 10kW Power Output Test ⚡
Shadow Sabre 12FET controller tested on an e-bike setup under real-world load conditions.

This was not a studio demo.
No polished dyno graphics.
Just a raw field test to observe power delivery, throttle response, thermal behavior, and controller stability during a high-power run.

The Shadow Sabre 12FET is built for serious DIY EV builders, performance e-bike projects, scooters, go-karts, and compact high-power electric platforms.

Early access batch is available for builders who want to test, tune, and push the platform in real applications.

Controller: Shadow Sabre 12FET
Test Application: E-bike
Peak Output Observed: ~10kW
Platform: VESC-compatible ecosystem

Shadow Sabre 12FET Brutal Test — Pushed up to 27 kW

We recently pushed the Shadow Sabre 12FET motor controller through a high-power test, reaching around 27 kW peak power.

This test was done to evaluate how the controller behaves under aggressive load conditions, especially for compact high-power EV applications where controller size, thermal performance, and phase current handling matter.

The Shadow Sabre 12FET is designed for builders working on performance-focused platforms such as:

E-scooters, e-bikes, compact EV builds, dual-motor setups, go-karts, and custom high-power projects.

This is still part of our real-world validation and early-access testing phase. More test videos, installation examples, and application-specific setups will follow.

**Shadow Sabre 12FET — Dual Motor Drive Test**

Development update from the Shadow Sabre 12FET controller platform.

In this test, we are running:

• 2 × Shadow Sabre 12FET controllers
• 2 × hub motors
• 1 × throttle input
• CAN sync harness between both controllers
• Bluetooth module for setup / monitoring

This test is mainly relevant for dual-motor electric scooter and DIY EV builders where both controllers need to respond predictably from one throttle input.

For scooter upgrades, the focus is not only peak current. The real work is in throttle behaviour, controller sync, regen behaviour, wiring layout, tuning flexibility, and thermal reliability under actual use.

We are currently preparing this platform for early-access builders and real-world validation.

If you are working on a dual-motor scooter build, message us with your scooter model, battery voltage, motor rating, and current controller setup for compatibility discussion.

**Shadow Sabre 12FET — 350A Phase Current Brake Test**

Early test reference from the Shadow Sabre 12FET platform.

This test demonstrates the controller under a high phase-current brake test condition, along with ECO / SPORT / MANIAC mode behaviour.

For builders comparing motor controllers, it is important to separate peak numbers from real-world usability. High current capability only matters when the controller is also practical to tune, thermally stable, predictable on throttle, and supported properly during setup.

The Shadow Sabre 12FET is being developed for serious DIY EV builders working on electric scooters, e-bikes, esk8, go-karts, dirt bikes, and custom EV platforms.

Current focus areas:

• compact high-power controller platform
• VESC-based tuning flexibility
• high-voltage support
• smooth throttle response
• thermal reliability
• CAN support for dual-controller setups
• direct setup support for early-access builders

For compatibility discussion, message us with your battery voltage, motor type/rating, vehicle platform, and current controller setup.
