MOLLE (Modular Lightweight Load-carrying Equipment) is a lightweight and modular carrying system from the military sector and serves as a standard for attaching equipment, bags and other gear to backpacks and tactical waistcoats.
The MOLLE system consists of many loops that are 1.5“ (3.8 cm) wide and 1” (2.5 cm) apart. This is also known as PALS (Pouch Attachment Ladder System).
This is used to attach the two battery plates and the hub to the battery belt. The corresponding latches also allow mounting on a tactical waistcoat.
