Dragonfly Energy Sues YouTuber Will Prowse

Dragonfly Energy, an industry leader in lithium battery technology and maker of Battle Born Batteries, today announced that it has filed a trade libel lawsuit against William Errol Prowse IV, known online as Will Prowse, and Prowse Publications LLC, in the Second Judicial District Court of the State of Nevada.

According to the press release, the complaint alleges that the YouTube DIY influencer used monetized content and non-standard testing to misrepresent Battle Born battery design, safety, and performance.

Founded and headquartered in Reno, Nevada, Dragonfly Energy has spent more than a decade designing and assembling lithium battery products relied on by customers, businesses, and families across the country.

The action seeks to protect the Company and its customers and partners, and the factual record surrounding Battle Born Batteries after Prowse’s sustained online campaign of allegedly false and misleading statements distributed through monetized online content. According to the complaint, Prowse presented his content as technical analysis while omitting critical context, misrepresenting product design and altering the batteries before testing them by removing structural components and running already-damaged units out of spec, producing a materially inaccurate portrayal of Battle Born Batteries’ real-world safety and performance.

“Dragonfly Energy respects and encourages good-faith product reviews, independent testing, and open technical discussion. This lawsuit is not about silencing criticism,” said Wade Seaburg, chief commercial officer at Dragonfly Energy. “It is about accountability when what we believe are false and misleading safety claims are presented as technical fact and amplified through monetized content. Those claims are being used to damage confidence in products backed by certified third-party testing, more than a decade of real-world field performance, and a trusted Nevada-based brand built by our employees, customers, dealers, and OEM partners. The people who rely on Battle Born Batteries deserve an accurate record.”

The complaint also alleges that Prowse previously reviewed and praised the same Battle Born battery product he later publicly disparaged, and that he received more than $200,000 from Dragonfly Energy in affiliate commissions, advertising fees, and related benefits tied to Battle Born branded products over multiple years. According to the complaint, Prowse later publicly denied that financial relationship while presenting his content as independent technical analysis, distributed the videos at issue through monetized platforms with affiliate links to competing products, and published them only after his affiliate and advertising arrangements with Dragonfly Energy had ended.

Product Safety, Testing, and Field Performance

Battle Born Batteries are designed with multiple layers of safety, assembled in the United States, and are supported by more than a decade of field performance. Relevant Battle Born product architecture has been ETL Listed by Intertek, a Nationally Recognized Testing Laboratory, to UL 2054 and IEC 62133 standards. Dragonfly Energy has deployed more than 400,000 batteries across real-world applications with an exceptionally strong safety record.

These deployments span demanding RV, marine, off-grid, industrial, and heavy-duty trucking applications, yielding extensive real-world performance data. Dragonfly Energy maintains that online videos are not a substitute for certified third-party testing, controlled product validation, or a complete understanding of lithium battery design, safety mechanisms, system integration, and actual operating environments.

Aim of Dragonfly Energy’s Case

The complaint seeks damages and injunctive relief to address the financial and reputational harm the Company alleges Prowse inflicted, and to prevent further statements about Battle Born Batteries the Company contends are false and disparaging.
