Changing the battery's capacity or voltage

This video is for anyone who is planning to change the battery configuration on their solar trailer.
Specifically, changing the capacity of their batteries by running the new battery wizard on the master Sunny Island.
This could be changing battery types, reducing or increasing the number of batteries on their trailer, decommissioning one of their two batteries, or changing the voltage rating of their system should they need to bypass a few cells in their existing batteries (because of a bad cell).
