In what regards? fluid movement inside the energy pack causing a surge?
I do not have a in-depth understanding of the battery technologies deployed by F1 teams, however i imagine they are similar to a commercial car battery as in they are comprised of multiple cells in both parallel and series to provide the provided energy storage. I also assume they have a cooling system, either a wet jacket or a copper jacket to help with heat rejection.
Note, there will be some major differences, most noteably the saftey margin for acceptable SOC (state of charge) temperature allowances etc for the super prototypes that the F1 teams use.
This multiple cell technique will have its advantages and prevent mass inertia movements from causing lots of fluid movement inside the cells, similar to the way that baffles in the fuel tank also help prevent inertial mass movements.
However, If the coolant fluid used in the battery is electrolytic in any way, that could have had a unforseen effect?
