I recently bought a second battery off ebay for wabash RT. It was new and still packed in the original packaging from Yamaha so I am mostly confident it is indeed legit and new.

For whatever reason, the power output is marginally less with it. It still works and everything seems fine but it is a bit less powerful at the same level of pedal assist as the battery that came with the bike.

It is is not really a big deal but I am curious has any thoughts on what may be causing this.
