The Daya Key lithium battery can be charged directly. Dayi universal direct charging model, Dayi universal battery electric wrench lithium battery charging lithium angle grinder electric saw electric hammer cutting machine charger. Find a switching power supply with a high current output. To produce a switching power supply greater than 20A, it is best to use one of 50A. Just use 8V50A switching power supply and soft silicone wires to change the charging one to a wired power supply.
If the sockets are the same, they can generally be used, because the lithium battery wrenches currently on the market are all 18V, and the maximum full-charge voltage is 21 V, 36 V is virtual. standard, and 25V is also a virtual standard.
. The actual battery contains 10 18650 cells. A single 18650 cell is 3.6V. One rowof 5 cells is connected in series to obtain a voltage of 18 V. Then both rows are connected in parallel to obtain the battery capacity. You can use a multimeter to measure it. When the battery is low, it is 18V, and when fully charged, the maximum voltage is 21V. Therefore, the key to buying an electric wrench is not to look at the V number of the standard. False industry standards are very powerful. So if the interfaces are the same, your battery will work 99% of the time.
The voltage of electric keys is generally relatively low, but the voltage of electric vehicles is generally above 36 volts. A mixed load is dangerous. It may damage the lithium battery of the electric wrench, or even cause a fire or explosion.
