Ladies and Gentlemen,

Baird Medical Investment Holdings Limited, a Cayman Islands exempted company (the “Company”), filed with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form F-1 (Registration No. 333-283249) (such registration statement, as so amended, being hereinafter referred to as the “Registration Statement”) for, among other things, the purpose of registering under the Securities Act of 1933, as amended (the “Securities Act”), (1) the resale from time to time by the selling securityholders named in the Registration Statement or their pledgees, donees, transferees, or other successors in interest of up to 34,415,562 ordinary shares, par value of US$0.0001 per share (the “Ordinary Shares”), and (2) up to 11,500,000 Ordinary Shares issuable upon exercises of up to 11,500,000 warrants of the Company at an exercise price of $11.50 per share, subject to adjustment (the “Warrants”) (together with the Warrants, the “Securities”).

We have acted as special United States counsel for the Company in connection with the transactions as contemplated in the Registration Statement. In rendering the opinions stated herein, we have examined and relied upon the following:

(a)	the Registration Statement, as amended, initially filed with the Commission on November 15, 2024 under the Securities Act;
(b)	the warrant agreement dated as of October 20, 2021 (the “Warrant Agreement”), between ExcelFin Acquisition Corp. (“ExcelFin”), a Delaware Corporation, and American Stock Transfer & Trust Company, LLC, as warrant agent (“AST”);
(c)	the warrant assignment, assumption and amendment agreement dated as of October 1, 2024 (the “Warrant Assignment Agreement”), among the Company, ExcelFin and AST; and
(d)	a specimen warrant certificate of the Company (the “Warrant Certificate”) in the form of Exhibit 4.2 to the Registration Statement.

The Warrant Agreement, the Warrant Assignment Agreement and the Warrant Certificate are referred to herein collectively as the “Transaction Agreements.”

We, as your counsel, have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion. We have not independently established the facts stated therein.

In rendering the opinions set forth below, we have assumed that (i) all information contained in all documents reviewed by us is true and correct; (ii) all signatures on all documents examined by us are genuine; (iii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the authentic originals of such documents; (iv) each natural person signing any document reviewed by us had the legal capacity to do so; (v) the Transaction Agreements have been and will be duly executed and delivered, (vi) the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective under the Securities Act; (vii) the Securities have been or will be issued and sold in compliance with applicable U.S. federal and state securities laws and in the manner stated in the Registration Statement; (viii) the Transaction Agreements and any other documents with respect to any Securities offered have been or will be duly authorized and validly executed and delivered by the Company and the other parties thereto; and (ix) any Securities issuable upon conversion, exchange, redemption or exercise of any Securities being offered have been or will be duly authorized, created and, if appropriate, reserved for issuance upon such conversion, exchange, redemption or exercise.
