You need to start with the limiting component in the power system: The ESC. If you have access to a good HV ESC like a Schulze or MGM then there are good options to go 12S. If you have a lower voltage ESC, then use the max input voltage the ESC can handle. Have you selected ESC's already?
If no, and you want 8S I would highly recommend looking at the Castle Hydra XLX2 which just got released. This is an 8S 400A capable ESC with logging.
