Shimano battery issues??

[Nickolp1974]

I have shimano e8000 system on a merida e120 900e and covered just shy of 600km so far in a little over 2 months. My battery health is at 95%

So my Mrs bought herself a merida big tour9 300 with the e6000 system and we went for a ride, both of us mostly in eco, we did 23 miles with 600m of climbing. Her battery used 2 bars and had approx 36 miles left in eco! Mine was about shot with around 4 miles left, awful. My eco is Set up to give 35nm torque with 75% assistance. I know I'll use more because of my extra bulk and greater rolling resistance but it's an awful comparison considering I have the supposedly superior cells in the battery.

That definitely doesn’t seem acceptable for a 2 month old battery - take it back to the seller for a once over, I suspect they will replace under warranty.
