Battery 40V Greenworks G40B4 Designed for all Greenworks 40 V devices. A modern model of lithium-ion batteries made in the latest production technology. It consists of high-end cells - A++, manufactured by the Japanese Panasonic company. The cells controlled by a special plate, the intelligent program of which regulates simultaneously charging/discharge in each cell, thus increasing battery life (up to 2000 charging/discharge cycles), battery life of the device (by 20%), and most importantly, lack of tool power loss when unloading the battery. Productivity is 4 A/h. The cells are locked in a solid housing. Conditions for ideal storage are 40% charge and temperature above 0°C. Main features High-class cells produced by Panasonic. Control plate for cell voltage balancing control during battery charging/discharge. Overheating/overload and deep discharge protection system. Long service life, up to 2000 charging and discharge cycles. Battery charging rate. Technical parameters Battery voltage: 40 V Battery capacity: 4 Ah Battery capacity: 144 Wh Weight: 1,3 kg
