The new ElectraFlow™ Plus Combi range from COX™ with the new 18V BOSCH battery system. With the unique Bosch CoolPack technology, the cells of special 14.4-36 volt lithium-ion batteries are perfectly protected, because the particularly conductive material on the underside conducts heat generated directly to the outside and thus prevents possible overheating of the cells - for up to 100% longer service life.
