We search for a charged partner of the X(3872) in the decay BX-K, X-J/ψπ-π0, using 234×106 BB̅ events collected at the Υ(4S) resonance with the BABAR detector at the PEP-II e+e- asymmetric-energy storage ring. The resulting product branching fraction upper limits are B(B0X-K+,X-J/ψπ-π0)<5.4×10-6 and B(B-X-K̅ 0,X-J/ψπ-π0)<22×10-6 at the 90% confidence level.
