I've bought these 4-set e-bike batteries before. They were poor quality and didn't last or work well. But this time the batteries, right from the get-go, were superb. When I charged them, it took about 30 minutes to top them off (they were obviously pre-charged). When the bridging cabling was installed, and the battery pack attached to the bike, it took off like a new one, a virtual rocket! I'm 75 years old, and it takes a lot to please me. I am pleased. Thank you for first class service, a top notch product and a confident feeling of good service should I need it.
