Customized lithium battery


What parameters do need to provide for a custom lithium-ion battery?

01. Input and output parameters of the lithium battery

02. The IP protection level of the Li-ion battery pack and the installation method of the battery pack needs to be determined. Also, it is necessary to consider how to install the lithium battery pack, which will play a big role in the design of the lithium battery

03. The size of the lithium battery will affect the capacity of the matching lithium battery pack. It is best to communicate with us before ordering lithium batteries to avoid the situation where the ideal differs greatly from the reality

04. What needs to be known in advance is that the service life of custom lithium batteries is expected. The service life of lithium LiFePO4 batteries is generally 2000 times

05. You need to know the usage time of the equipment because it will affect the capacity of the lithium battery pack that needs to be customized

06. For motor-like devices that support lithium batteries, you need to know the maximum power when starting these induction loads

07. Since the voltage of the lithium battery pack is not a fixed value, but a wide range, you need to ensure that the equipment can withstand the corresponding voltage value

Determining the size and shape of the battery first will save us a lot of time in development and design
