We report the discovery and characterization of a new M-dwarf binary, with component masses and radii of $M_1 = 0.244_{-0.003}^{+0.003} \, \mathrm{M}_{\odot }$, $R_1 = 0.261_{-0.009}^{+0.006} \, \mathrm{R}_{\odot }$, $M_2 = 0.179_{-0.001}^{+0.002} \, \mathrm{M}_{\odot }$, $R_2 = 0.218 _{-0.011}^{+0.007} \, \mathrm{R}_{\odot }$, and orbital period of ∼4.1 d. The M-dwarf binary HATS551−027 (LP 837−2...
