I'm in the process of getting an e-tandem built up for me and my wife. The process is being delayed however because the builder can't source a Shimano BT-e8016 630Wh battery. Does anyone know if there are any non-Shimano brand replacements for this battery or if that is even a thing with e-bike batteries. Or alternatively, anyone know of a source for the actual Shimano branded battery?
Thanks,
Michael
