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.
