Hey all,


I have a Shimano Conduit electric bike and I was interested in doing some much longer rides and the battery it comes with will do 40ish miles tops. I looked for a replacement battery so I could carry two but they appear to be non-existent from Trek or Shimano. Does anyone know if I could intstall a toggle switch to this system controller and be able to add another brand external battery to get more life?


Thanks!
