Lithium Battery Fan Installation Steps
The "installation steps" for a lithium battery fan usually refer to battery installation or replacement, rather than assembling the entire unit (since most lithium battery fans come as finished products).
Steps for Replacing or Installing a Lithium Battery:
Power Off and Disassemble: Ensure the fan is completely powered off to avoid the risk of short circuits.
Remove the Outer Shell:
Most models need to be disassembled from the bottom; first remove the anti-slip pads, then unscrew the screws.
Some models (such as neck-hanging or astronaut fans) need to pry open the shell along the seams.
Identify Battery Type and Wiring:
Common batteries include 18650 (such as 3 cells in series), 14500, etc.
Take a photo to record the original wiring method and distinguish the positive and negative terminals.
Replace the Battery:
Use a spot welder to connect the new battery (soldering is not recommended as it may damage the cells).
If the original has no protection board, it is recommended to add one to improve safety.
Reassemble and Test:
Reinstall the battery pack, connect to the main control board, and power on to test whether it works properly.
Ensure all screws are tightened to avoid looseness and abnormal noise.
