The Blue Bird Backpack Pack Battery 50.4V-18Ah is a high-performance lithium-ion battery with fast recharging. It has a long life - up to 3 times longer than nickel-cadmium batteries, reducing the need for recharging during long periods of use. The charge of lithium-ion batteries does not weaken unlike nickel-cadmium batteries. While the latter gradually reduce power, lithium-ion batteries maintain constant power throughout the cycle. The same load is sufficient for the entire work cycle without a decrease in engine speed. The battery works at full power until it is completely exhausted. Lithium-ion batteries last 3-4 times longer than traditional nickel-cadmium batteries and store energy longer so they lose less. It is characteristic that the Blue Bird Backpack Pack Battery 50.4V-18Ah can be recharged and fully functional up to 2000 times! These batteries have no memory effect and can be recharged even if they are not fully discharged, always maintaining maximum efficiency. They also have an LED indicator that shows the battery charge level. In addition, they do not present overheating problems, providing maximum safety. They are lightweight, having an optimal power-to-weight ratio, weighing about 1/3 of nickel-cadmium batteries. The Blue Bird Backpack Pack Battery 50.4V-18Ah is environmentally friendly, while tools and machines powered by lithium-ion batteries are recyclable and produced without heavy metals. The Li-ion battery charger, which comes with the Battery Pack and connecting cable, reduces power consumption by an average of about 35%, and features a heavy-duty, long-lasting air filter. The Blue Bird Backpack Pack Battery 50.4V-18Ah with Cable & Battery Charger is suitable for use by tools and machinery used in medium to large sized gardens and grounds.
