My Redmi Note 10 Lite (Note 9 Pro) 's battery is busted, I think the BMS went bad but the cells are good.
But the problem is the back glass panel is cracked as well and the service center is quoting about Rs.1400 for the glass and Rs.800 for the battery.

I usually buy back-panel replacement for Rs.100 from Kolkata Fancy Market but I'm now in Jaipur and have no information on local repair shops.

Someone on a LG V30 post suggested maxbhi but I'm skeptical of authenticity of the battery.
I just need the battery to be genuine, is there any way I can get one?

Maxbhi battery: For my Redmi Note 6 Pro, I bought batteries two times from Maxbhi as was not available with service center and both times it swollen within 3 months.
