I see that the pad is missing.
This should be fixable by soldering a mirco wire to what that pad was connected to and soldering the fpc connector back on that cable.
In some cases, some pads are no stuff. Meaning there where not used in the end design and there for does not matter that it is missing. That is less likely for a battery connector
Any shop that specialises in micro soldering should be able to fix this for you.
Our shop does it if your interested. We are situated in Canada. Innovatrix Repairs.
