①Is it a regular processing manufacturer (you can download the company to check the manufacturer’s industrial and commercial information, and whether there is an administrative license to process lithium batteries) ②Which brands of batteries are used, are they cylindrical or square? Is it a power cell, an energy storage cell, or a disassembled second-hand cell (energy storage and disassembly are cheap) ③What is the discharge rate of the battery? The discharge rate of the power cell can reach 3C-5C, If the magnification is small, it may be an energy storage battery, and high-current discharge may cause heat or even hot. ④It is also a 4812 lithium battery, and some manufacturers use 13 strings of batteries (charging voltage 54.6V, just look at the charger). The price is cheap, [Daqin Lithium 4812 has 14 strings, charging voltage 58.8V] ⑤It is also a 72V lithium battery, some manufacturers use 20 strings of batteries, (charging voltage 84V, just look at the charger), so the price is cheap, [大秦72V21 string, charging voltage 88.2V] ⑥ Does the protection board have over-charge, over-discharge, short-circuit protection functions, with its own equalization function ⑦Is the lithium battery plug cord flame-retardant? ⑧Is the lithium battery capacity up to the nominal capacity? , Or false standard capacity ⑨ Whether the actual battery life is up to the statement: Some pictures and content of the articles published on this site are from the Internet, if there is any infringement, please contact to delete the previous one: Lithium battery data recovery skills and lithium battery recovery skills
