Description of the battery Kosovo, designed to work with a disc or vein head for cutting grass and bushes. Due to its high power and long working time, it can compete with internal combustion devices. It is quieter and safer, as the engine components do not get very hot. It is launched by pressing a switch instead of using a rope. The soft start feature allows for a 6000 rpm hollow core motor. The disc measures 230mm with a 25.4mm double vein head in the body, which has easy winding veins. The core thickness is 2.0mm. It includes a drive shaft for easy transport and is compatible with an 18V system, operating with two batteries simultaneously: 36V = 2X 18V. Recommended batteries are YT-82843 (3.0 Ah) or YT-82844 (4.0 Ah) - 3.0 Ah batteries not included. The runtime is more than 30 minutes with either the vein or disc.
