Have you ever wondered, how much is the total cost of owning & using an electric scooter?
In this post, I collect all the data of my past 4 months. In this time I’ve been using a Xiaomi MI M365 scooter extensively, my total mileage is 1400 kilometers. It replaced my public transportation & taxi usage drastically.
The table below represents orders including shipping to Hungary or in some cases, the prices in Hungary.
But, how much did it cost?
Some of the items might need an explanation for the ones not familiar with electric scooters or this exact model’s faults, I will follow up on them in later posts.
Summary for the falcon, the extra shaft lock piece & rear fender: this model has multiple design or manufacturing faults that cause parts of it breaking, and these are workarounds to avoid of this happening.
Also, defects are part of life if you are using an electric scooter (and don’t want to shake your brain & your battery terminals off with a solid tire), hence the slime, the pump and the tire repair in a bike shop.
Other details
Summary
So, as we can see, the total cost so far was the double of the scooter’s price, still I think it was worth it. It was very fun to travel this way in the summer, it gave me so much freedom and joy.
It’s a bit sad, that my battery failed a few days ago, solving that is in early stages right now.

What do you think? What are your figures? Let me know in the comments section!
Dear Kopias,
Appreciate the detailed explanation, especially reinforcements you have done at your M365.
Regarding the last point, battery, I am curious to listen for more. Do you think that the battery completed its life span or the issue is related to other factors (like water exposure etc.)? If it’s the life span, 1400 km would mean an average of 70 charging cycles, which is far lower than the ideal number of 500-1000.
Cheers,

Dear Evrim,
Thank you for commenting!
My battery is still at a professional battery repair shop (outside of warranty, non xiaomi affiliated service), so I can’t say too much yet.
I have taken the battery apart before giving it to the service shop, and verified that the battery connections are intact. So that can be excluded.
What is still possible:
– Died cells (cell group nine or ten might be)
– Damaged bms (water leakage can be a cause)
– Firmware bug (i’m using a modded fw)
So we’ll see. They called me last friday, telling me that they don’t see any problems. We settled on that they will do a discharge test, and we’ll see. When I get it back i will reinstall the stock firmware and test it…
So stay tuned, I will write a follow up on it, when I get more information!

Thanks for the explanation!
It’s impressive that you opened up the battery pack 🙂
I am sure you use a tool to see the health of each cell, which could (in)validate the died cells possibility.
I am interested in trying some protection for the battery pack under the device. I wonder covering that plate is acceptable, as closing it may cause other issues related to ventilation (using just ambient air). From this explanation I assume you have not protected against water (rain, puddles, …)
Good luck on the repair 🙂

Dear Evrim!
I’ve received my battery back, they did not found any problems with it:)
So they resetted the bms, they told me to fully charge and fully discharge it two times.
I’ve also installed back the stock FW just to exclude one parameter from the equation.
So since then it’s working quite well. There is a bit of voltage difference around cells 9/10 but it works fine and doesn’t drop from 55% to 3% in a minute.
I don’t think everything is fine, but it works currently:)
