Panasonic new 20700 cells
presented bigger battery cells at last week’s Eurobike. Their newly developed 20700 cell (20mm diameter and 70mm high) is in particular targeting e-MTBs that have downtube mounted batteries. By the way, Eurobike indicated that integrating the battery in the downtube is currently the general trend among electric Mountainbikes. Panasonic says on its 20700 cell, “This battery call has been developed for compact and integrated designs.” Panasonic offers two 36V integrated battery versions with 8 and 12Ah allowing for 288 and 432Wh.
Panasonic is on the right track as far as downtube mounted batteries, but, the capacity of the 36 volt battery design does not appear to be much of a game changer ,
