Reliable.
Lithium batteries are produced at home. Generally, it is reliable to assemble and produce them at home (the relevant materials are all finished products and have been tested before leaving the factory). the requirements are complete and raw material testing is necessary. Line connection, finished product testing and insulation packaging equipment and corresponding instruments and tools. A set of lithium battery assembly equipment ranges from 10,000 to 20,000 or even hundreds of thousands (prices are lower for small volumes).
Assembling lithium batteries requires no skills
It is dangerous.
Because lithium batteries are more likely to explode than lead acid batteries when placed in a household battery, continued charging of the battery without protective measures will present amajor safety risk.
Lithium-ion batteries are absolutely harmful to the human body. The most harmful thing is the electrolyte solution. The electrolyte is a volatile organic liquid and is obviously corrosive. Prolonged inhalation of volatile gases may cause damage to the respiratory tract.
Technology is required. Assembling lithium batteries requires certain skills because there are many details that need to be considered during the assembly process. For example: after a newly assembled lithium battery has been used for a while, the voltage of the batteries should be checked in groups. to avoid overshooting and overdischarging. When selecting a battery, you should pay attention to whether the internal resistance is too large, the parameters are not too different, etc. It is not recommended to attempt to assemble lithium batteries without une certain base, as this could cause an explosion.
