Ladies and Gentlemen:

We have represented Twin Vee PowerCats Co., a Delaware Corporation (the “Company”), in connection with a registration statement on Form S-4 (the “Registration Statement”), filed by the Company on the date hereof with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement provides for the registration by the Company of up to 4,000,000 shares (the “Shares”) of the Company’s common stock, par value $0.001 per share, to be issued upon consummation of the merger (the “Merger”) of Twin Vee Powercats, Inc., a Florida corporation (“Twin Vee Inc.”), with and into the Company, with the Company surviving the merger, pursuant to that certain Agreement and Plan of Merger, dated September 8, 2022, by and between the Company and Twin Vee Inc. (the “Merger Agreement”).

In connection with this opinion, we have examined, the Registration Statement in the form filed with the Commission on the date hereof, the Merger Agreement, the Company’s Certificate of Incorporation, the Company’s Bylaws, each as currently in effect, and original or certified copies of such records of the Company and such agreements, certificates of public officials, certificates of officers or representatives of the Company and others, and such other documents as we deem relevant and necessary as a basis for the opinion hereinafter expressed. In such examination we have assumed the genuineness of all signatures on original documents and the conformity to original documents of all copies submitted to us as conformed or photostat copies. As to various questions of fact material to such opinions, we have relied upon statements or certificates of officials and representatives of the Company and others.

In rendering this opinion, we have assumed that prior to the issuance of any of the Shares that all other approvals for the issuance of the Shares referred to in the Registration Statement have become effective and that no shares of capital stock of the Company are issued or commitments to issue capital stock made by the Company prior to effectiveness of the Merger Agreement, other than as expressly permitted by the Merger Agreement.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Shares, when the Registration Statement has been declared effective and the Shares have been issued and paid for in the manner contemplated by, and upon the terms and conditions set forth in the Registration Statement and the Merger Agreement, will be validly issued, fully paid and nonassessable.

We are opining solely on all applicable statutory provisions of Delaware corporate law, including the rules and regulations underlying those provisions, all applicable provisions of the Delaware Constitution and all applicable judicial and regulatory determinations. This opinion is limited to the laws of the State of Delaware as in effect on the date hereof and we express no opinion with respect to the laws of any other jurisdiction.
