hello all my m8 has orbea with shimano steps 500 and I believe the battery is described as 400 w
he is thinking of carring a spare 400w as he is going to be doing some rather long rides.
so I thought I would ask on the forum if there is a source for shimano or pattern battery (400w)
battery.

thanks all
