Each battery in the 18650 Battery Pack is connected with a fuse to prevent the single battery from overheating, endangering the overall battery overheating, and each battery fuse is beautifully welded. The central part of the battery is wired to the battery control module, which is used to detect the voltage of the battery pack, so as to ensure the normal operation of the battery pack. The whole body of the battery is wrapped by a transparent plastic shell, and both sides are surrounded by metal radiating plates. The thickness of the battery is slightly thicker than the sole, which belongs to the flat long type battery pack, which leads to a great reduction in the center of gravity of the vehicle. The overall battery pack is pretty well protected.
