58FV means the battery's rated voltage is 58V. The voltage is 18V. There is no difference in the actual voltage of rechargeable electric wrenches marked 58V, 28V and 26V in the domestic market, because the lithium battery wrenches currently on the market are all 18V, and the maximum voltage at Full load is 21V, so the marked voltages are all wrong. The actual battery contains 10 18650 cells. A single 18650 cell is 3.6 V. A row of 5 cells is connected in series to obtain a voltage of 18 V. Then both rows are connected in parallel to obtain the capacity of battery. You can use a multimeter to measure it. When the battery is low, it is 18 V, and when fully charged, the maximum voltage is 21 V.
Yes.
