Spare parts for Larkbook X

I got last year - 2022, July - my Chuwi Larkbook X .
now a couple of days before I have now issues with my Laptop Battery.
I can’t charge the battery. over direct power and over USB.
the LED is on and red on left side of Laptop.
looks like the battery is defect.
Where could I get a new one, please ?
