Mobile screen is cracked, need to change battery back panel came out

@kalam86420 easy enough ;-) Use this guide Reemplazo de Batería del Samsung Galaxy S10+ for the repair and you can get the battery from here Galaxy S10+ Battery (depends on where you reside). Due to  shipping regulations, we can only ship lithium-ion batteries to physical addresses inside the contiguous United States (lower 48 states) via Ground shipping methods. We cannot utilize Air shipping methods for shipments containing batteries. If you reside outside the USA you may need to find a supplier closer to your geographic region.

The first guide also shows you how to remove the back cover. If you need to replace it you can get that one from here Galaxy S10+ Rear Glass Panel/Cover and the adhesive to keep it secured is available right here Galaxy S10+ Rear Cover Adhesive

Repair is War on Entropy!
