What's the difference between an electric wrench 28V and an 32V?
Because the current lithium wrench on the market are 18V, the full power of the highest voltage of 21V, 32V is a virtual standard, 28V is also a virtual target. The actual battery pack contains 10 18650 electric cores, a single 18650 of the core is 3.6V, a row of 5 series to get 18V voltage, and then the two lines in parallel, to get the capacity of the battery pack. You can use a multimeter to measure the amount of electricity, when the amount of electricity is 18V, full of electricity when the maximum voltage is 21V.
There is no difference between 28V and 32V.
Electric wrench is power or battery powered wrench, is a kind of high strength bolt tightening tool, also known as high-strength bolt gun. It can be divided into impact wrench, torsional shear wrench, fixed torque wrench, corner wrench and angle spanner.
