Receiving electric vehicle battery repair, the customer requested to only replace the damaged CELL 

I accepted to make an electric motorbike battery from a customer that had been repaired elsewhere for 2 weeks before it was damaged and could not be used. The car owner asked me to check and only replace the damaged CELL.
I took it apart and was very surprised with the way the worker I received it handled it. Please share your thoughts on how to make this battery. In this video PART 2, I agreed with the customer to replace an entire battery with a new CELL battery
