Frequently Asked Questions

Q: What voltage range is this brushless motor control board compatible with?

A: This 60A angle grinder control board is compatible with lithium battery systems operating between 18V and 21V, making it suitable for most standard cordless power tool battery packs in that voltage range.

Q: Will this control board work with my electric wrench, or only angle grinders?

A: This brushless speed controller is designed to work with both angle grinders and electric wrenches that use brushless motors. It is specifically compatible with DAYI-style tool housings, but please verify your tool's motor type and voltage requirements before purchasing.

Q: What should I do if the board makes a buzzing alarm sound after installation?

A: A buzzing alarm is typically caused by a gap remaining in the tool shell after reassembly. Ensure the speed-control switch is fully pressed down and that there is no gap between the shell components. Re-check that all screws are tightened and the casing is fully seated before reconnecting power.

Q: Is this board easy to install for a DIY repair project?

A: Yes — this control board is designed for DIY electrical repair and tool rebuilding. Follow the step-by-step installation instructions provided (connect wires → fix motor → install case → tighten screws → check shaft rotation → connect power → seat the switch). If you are new to circuit board replacement, we recommend basic electronics knowledge before proceeding.
