The battery pack was in good shape. I made two measurements Vbattery =38V weight =950 g
At this moment it difficult to say about durability of this battery. But arrived properly storaged. I charged it to full as seller declared. I ordered it for Kawasaki Streetboard KX-ST10,1 10 and started without any problem. Before I ordered a battery from my country and I have got broken product. So sellers from far east are dependable. I do not expect incredible quality of this battery, especially for price that was bought. it's worth the wait
