LP 413-53 AB is the shortest-orbital-period ultracool dwarf binary at field age, with an orbital period of 17 hr, not associated with the Hyades, with the updated radial velocity (+6.61+/-0.02 km/s) from Hsu et al. (2023) (2023ApJ...945L...6H). The vast literature assuming it's in the Hyades is incorrect.
