Quantya evo 1 2011 battery problem

[Quantya evo 1 2011]

Hello, I have a Qantya evo 1 2011 with all original parts, the problem is that the battery is damaged as far as I understand, or 2 damaged cells and I think they are somewhere around 800 euros, I don't know exactly, I was also informed that if I replace them it is possible for these 2 others to break, I'm thinking of getting another battery but I don't know what I need and where to buy all the components for the battery. One component that gives me problems is an 8.4 KW BMS, I don't know why where to buy it, the battery is 40Ah and 48V, I really want to bring this back to life. If you can give me all the components in detail and where to buy, I would be grateful for this battery. I also left some pictures of the battery. Thank you!

Hi, I can offer you an older, fully functional Quantya battery with 80% cells capacity for 250 Euros. Also if you would be interested, I also have 4x original Kokam 40Ah cells with 80% capacity (15 Euros each).

Hi!
You need to replace your Qantya Evo 1's battery with lithium-ion cells (40Ah, 48V) and an 8.4KW BMS. It's important to use compatible parts to avoid future issues. You can find these components on sites like Alibaba, eBay, or specialized EV shops like Electric Scooter Parts or EV Works. Make sure to check your charger’s compatibility with the new setup.
