1. A multi-chambered electrolyte storage tank, for a redox flow battery system, including:
first and second electrolyte chambers, and a bulkhead, wherein
the first and second electrolyte chambers are fluidly coupled to first and second sides of a redox flow battery cell, respectively,
the first and second electrolyte chambers include first and second liquid electrolyte volumes, respectively, and
the first and second liquid electrolyte volumes are separated by the bulkhead positioned therebetween, wherein the bulkhead includes a spill hole, the spill hole positioned in an interior of the bulkhead on the bulkhead,
first and second return inlet pipes fluidly coupled to the first and second electrolyte chambers, respectively, wherein the first and second return inlet pipes enter the multi-chambered electrolyte storage tank above the spill hole and are configured to deliver returned fluids to submersed positions below the spill hole in the first and second liquid electrolyte volumes, respectively, and
first and second return manifolds submersed and fluidly coupled to the first and second return inlet pipes, respectively, at the submersed positions in the first and second liquid electrolyte volumes, respectively.
