Four taboos for using lithium batteries.

Four taboos for using lithium batteries.

Lithium batteries are sensitive to high temperatures. Long term exposure to excessive heat can significantly reduce the lifespan of lithium batteries, and in severe cases, explosions can occur due to increased internal pressure. Even if there is no explosion, lithium batteries will quickly be scrapped in high heat, largely due to the high temperature of their working environment.

The second highest current, for example, 18650 battery cells have a 3C discharge, while your electric vehicle has an 8000W battery. Using a battery cell with a current lower than your electric vehicle's discharge current can cause the lithium battery to have a high temperature transition, a high current, and a shorter lifespan. It can also lead to bulging and scrap. If your electric vehicle has a high power output and fast speed, it is recommended to choose 18650 battery cells with a current of 10C. Choosing the appropriate battery cell is obviously very important!

Three full battery storage, the full charge of a ternary lithium battery is 4.35V. Currently, maintenance boards on the market stop charging at 4.2V, so many people say that electric vehicle lithium batteries do not have the nominal capacity. In fact, this is the reason why ordinary long-term storage of electric vehicle lithium batteries can fill 50% of the TV. For example, when you buy a new phone, many of them have 50% of the power when turned on. If the fully charged storage time is long, it will reduce the capacity of the lithium battery. Except for lithium iron phosphate and lithium titanate, which can be stored at full capacity, it is also important to choose a high-quality maintenance board. The taboo for lithium batteries is over charging and over discharging. Three element lithium will be scrapped after one over discharging, and over charging will inevitably result in bulging and scrapping.
