Anderson plugs are not waterproof. The Anderson plug itself is not a waterproof structure, which can easily cause water to enter the entire battery pack through the Anderson plug, causing a short circuit or even a fire or explosion. There are two main methods of waterproofing the Anderson plug. One is to make a hole in the shell and then place a waterproof line card. By extending the connecting wire, the Anderson plug is placed externally. At this time, the connecting wire is exposed to the outside and is prone to wear and tear, leading to short circuits. The second is to open a hole in the casing and build the Anderson plug into it, and the Anderson plug is fixed on the casing with screws. After the entire battery pack is placed in the battery compartment, the entire battery pack is filled with glue to make it waterproof. The overall glue filling cost is high and is not suitable for large quantities. Production.
