Safety First: While LiFePO4 offers inherent safety advantages, these cells require proper handling and expertise to assemble a safe battery pack. It's crucial to understand and follow recommended safety precautions during assembly and use.

Battery Management System (BMS) Required: These cells are not equipped with protection circuits. A BMS is necessary to manage the charge and discharge cycles, ensuring safe and optimal performance of your battery pack.

Assembly Instructions: Assembling a LiFePO4 battery pack requires a strong understanding of electronics and proper cell assembly techniques. EVE provides limited instructions, and incorrect assembly can lead to fire, explosion, or personal injury. It is crucial to possess the necessary knowledge and experience before attempting to assemble your own battery pack.

For your safety, we strongly recommend consulting with a qualified battery assembly professional or researching LiFePO4 cell assembly best practices extensively before proceeding.
