Wisper bikes are powered by high quality lithium ion batteries.
To achieve maximum battery life, it is important that a lithium battery is correctly maintained. All lithium batteries gradually lose capacity and therefore reduce the range of an electric bike. If well maintained a high quality lithium battery will give several years and thousands of miles of good reliable service.
The latest Wisper 700Wh LG batteries are installed with the very latest battery technology. These state of the art batteries automatically assist in keeping a battery in perfect condition.
