How is this possible? (BMS replaced)

I have had a Carbon GT and as winter was coming in AND I was not riding it as much as I wanted, I decided to ship it to Evolve HQ in Germany where it was bought for a checkup.

So the guys there emailed me back and told me I needed a belt replaced and that they had carried out other maintenance work covered by my guarantee. They upgraded the remote firmware, and more importantly they changed BMS.

We got a batch of sunny days these past 10 days here in Greece so I went our for a ride after 3 months of not being on the board.

SOoooo my question is this. Is it possible that by changing the BMS the board has a MUCH smoother acceleration curve AND it so so much quieter!!!???? I am blown away on how different the board feels.

I had had the occasional instantaneous dropouts myself but never something serious and ιν general my board was 99% fine. But now after it came back from Germany it feels like a different bard. Same total speed, same acceleration but smoother...generally very very happy.

Do you guys/gals think that the BMS plays such an important role?
