This series connection only increases the total voltage (6V+6V = 12V) and the total stored energy potential in watts. If each 6V battery in the string was rated at 225 Amp hour (20Hr) to 100% DOD, the final battery bank rating would be 12V 225AH and would have a total of 2700 watts of stored energy to 100% DOD.

The CTP approach is to use fewer, larger battery cells, which reduces the number of connections and adapter parts of the battery, simplifies assembly, and potentially increases reliability. For example, the Tesla Model S battery pack has more than 7000 battery cells, each connection of which is a potential point of failure/malfunction.
In this example the battery pack voltage is 12 volts which is exactly the same as each of the individual 12-volt batteries.
