A battery system, a method of controlling the battery system, and an energy storage system including the battery system are disclosed. The techniques can be implemented, for example in an image editing application that is executable on a computing system. The flange of the second member can include mounting locations spaced along the flange for supporting fasteners securable at a plurality of locations spaced along the exterior wall. In some embodiments the brush holder includes a channel, such that at least a portion of the mounting block is disposed within the channel of the brush holder. Generating the second event grouping includes selecting the second set of events based on the local times of the events in view of the timezones of the events. The reservoir is optionally one that has been used for thermally enhanced oil recovery and thus is already warm, minimizing heat losses.
