We present recent progress on non-BPS multi-black hole systems in ungauged N=2 supergravity coupled to vector multiplets. Focusing on the composite non-BPS system, which allows for arbitrary non-BPS charges to be realised at each centre, we discuss the structure of the resulting solutions. Using these results, we study the binding energy of the composites and show the existence of walls of marginal stability for generic choices of charges.
