What is the difference between 12v and 16.8v lithium
The difference between the two: 1. Different voltages: One is a voltage of 12v, and the other is a voltage of 16.8v; 2. The number of revolutions is different: The motors used at different voltages are different, the higher the voltage, the greater the rotation speed; 3. Difference in battery capacity: The motors with different voltages need to have higher electronic capacity. working principle: The DC motor rotates, and after being decelerated by the planetary deceleration mechanism, the drill chuck is rotated to drive the work of the bit or the drill bit. By pulling the lever of the forward and reverse switch, the polarity of the DC power supply can be adjusted to change the forward or reverse rotation of the motor, so as to achieve the operation of disassembly and assembly. Lithium drill uses: 1. Used for screw-in and screw-out operations of screws, wood screws, self-tapping screws, etc., and can also be used for drilling of various metals and wood. 2. According to the voltage size of the rechargeable battery block, there are 7.2V, 9.6V, 12V, 14.4V, 18V and other series. 3. According to the battery classification, it can be divided into two types: lithium battery and nickel-chromium battery. 32313133353236313431303231363533e58685e5aeb931333366306533 Lithium battery is lighter and has lower battery loss.
