Dave is always on the look out for new ways to ensure that operating our wheels are as consumer friendly as possible. He's found a new battery that has new technology that he feels makes it more consumer friendly. While we loved our prior batteries we feel that this one with it's smaller dimensions, improved digital display, and cable management to be more friendly to our flock. We will have batteries available at Rhinebeck and are expecting another shipment to arrive after we return from Rhinebeck. We plan to have batteries available once the shop reopens on November 16th.
