Frequently Asked Questions
Q: Which brushless electric wrench models is this control board compatible with?
A: This drive control board is designed specifically for Dayi 2106, 161, and 169 brushless electric wrench models. It also functions as a general-purpose brushless sensorless control board for 18V–21V brushless angle grinders and polishing machines with similar power ratings.
Q: What battery voltage does this brushless drive control board support?
A: The board operates at 18V nominal (5-cell lithium series, fully charged to 21V), at 300W. Battery packs labelled 48V, 68V, 88V, 98V, 128VF, or TV are all compatible — their actual output is 18V using 5S2P or 5S3P lithium cell configurations.
Q: What happens if I power on the control board before completing the full assembly?
A: Powering on the board before all wiring is connected, the motor is fixed, the case is assembled, and the shaft spins freely may trigger a buzzing alarm and could potentially damage the control board. Always complete the full assembly sequence before applying power.
