It is used for the repair and assembly of battery packs, and is limited to those who are familiar with battery performance and have practical experience in battery assembly.Preparations before assembly: (1). If new batteries are used, please note: 18650 power lithium batteries must be selected, b. A set of 7 cores must be equipped with resistors and capacitors so that they have the same electrical U. (2). If servicing old batteries, test the voltage of each battery. If the voltage is different, charge each battery to the same voltage value.VERY IMPORTANT: Before soldering the PCB, make sure the U of each cell is the same.Board Specifications:A. The built-in IC detects the battery power U and current. And remember the number of uses!B. Battery detection and protection: overheat protection, overvoltage protection, undervoltage protection, overcurrent protection, overcharge protection.Stable quality and anti-vibration. The best partner for DS machinesColor: any color such as blue, white, green, red, etc. PCB color and version number vary according to the actual latest stock.PCB designs may change due to changes in supply chain and processing technology.warn:A. Please use 18650 power lithium battery, the internal resistance is small, the model is the same, the parameters are the same,Do not use ordinary lithium batteries for energy storageB. Please test the power U of the 18650 single battery before assembling.And charge a single battery so that each 18650 battery has the same power U.Colour: Blackmaterial: plasticPackage Contents:1 set*battery boxOnly the above package contents, excluding other products.Note: Different lighting and monitors may cause the color of the item in the image to be slightly different from the actual item.
