Heat dissipation.

According to relevant information from Juda Lithium Battery, a cooling fan is installed at one end of the lithium-ion battery module, and a ventilation hole is left at the other end to accelerate the process. air flows between the gaps in the battery cells, bringing the high heat that occurs when the battery core is operating.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation product of rechargeable batteries, lithium metal batteries, was born in 1996. Its safety, specific capacity, self-discharge rate and performance-price ratio are better than those of lithium-ion batteries.

.....Nowadays, batteries are generally 2500mAh. It is best to use a standard 1A charger. Generally, it takes 3-4 hours to charge a fully charged 18650 battery!... If you use a high current charger, the charge will be very hot, which will cause certain damage to the battery... Moreover, high current charging can only charge about 80%, and then switch to low current to continue charging. In fact, the full charge time is almost the same... For the previous 1500 mAh small capacity battery, about half the time was enough...

......As for these batteries with a capacity of more than 3,000, most of them are just gadgets......
