When choosing a lithium battery case, the following factors need to be considered:
1. Application scenarios: Different application scenarios have different requirements for the material and performance of the housing. For example, lithium batteries used in electric vehicles need to have high temperature resistance and fire and explosion-proof performance, while lithium batteries used in handheld devices need to be lighter and durable.
2. Safety: The shell of the battery needs to have good sealing and explosion-proof performance to prevent safety issues such as leakage and thermal runaway inside the battery.
3. Sealing: The sealing of the casing is also an important consideration, because if the casing is not tightly sealed, it will cause leakage and damage to the battery during use.

4. Heat dissipation: The heat dissipation of the battery also needs to take into account the design of the casing to ensure that the battery will not overheat in a high temperature environment.
5. Cost: Lithium battery shell materials are different, and the price will also vary, which needs to be selected according to specific needs and cost budget.
To sum up, when choosing a lithium battery case, it is necessary to select appropriate materials and design solutions based on specific application scenarios and requirements, considering factors such as safety, sealing, heat dissipation, and cost.

Therefore, I recommend TEFOO ENERGY standard lithium battery, which is convenient for operators to carry out mobile indoor and outdoor operations. Providing continuous, efficient and stable mobile power supply has become the greatest guarantee for the normal operation of such equipment. The solution uses high-performance batteries, so that the entire battery has the characteristics of high energy ratio, light weight, small size, high cycle life, high safety, and high consistency. The battery is very convenient to use, and the original battery can be directly replaced on site.
