Frequently Asked Questions

Which power tools does your controller cover?

Drills, impact drivers, angle grinders, circular saws and similar tools — with brushed or brushless motor control, soft-start, electronic braking and stall protection.

How are the motor and battery protected?

The controller monitors current, voltage and temperature in real time, providing over-current, over- and under-voltage, over-temperature and locked-rotor protection with staged derating.

Is the trigger response adjustable?

Yes. Trigger curves, cruise settings, torque stages and LED feedback are parameterized so one platform can be tuned for each tool family.
