Controller Max Voltage Question

Question: Alltrax lists the max voltage of the 7245 controller as 90V. Assuming that open circuit fully charged voltage will be 12.8V per battery, this makes an "84V" string 89.6V, just under max. Is it possible to actually run 84V with this controller? Sure, with some surface charge it will be over 90V, but couldn't you just turn the electric heater (or any load) on for a minute to get rid of the surface charge?

Just asking.
