At present, there are not many institutions doing lithium battery training in China. Some are organized by training institutions, which are not very practical, and some are trained by lithium battery manufacturers. This kind of training is good, practical and targeted. You can go to Tolde Lithium Battery Training College to find out. It is said that the team of this organization has been engaged in the research, development, production and training of lithium batteries for fifteen years. I hope it will help you. Please adopt it, thank you!
