Reno, Nevada — Dragonfly Energy Holdings Corp. (Nasdaq: DFLI) (“Dragonfly Energy” or the “Company”), an industry leader in energy storage and maker of Battle Born Batteries^®, today announced that World Cat, the world’s largest producer of power catamarans, has expanded its integration of Battle Born^® power systems across new models. Following the successful deployment of the Company’s system on the World Cat 325 DC and strong performance over multiple seasons, World Cat has selected Battle Born Batteries as standard equipment for its new 400DC-X Island dual-console model.

World Cat first partnered with Dragonfly Energy to engineer a lithium power system tailored to the 325 DC’s electrical load, onboard comfort features, and space constraints. Built around the Company’s patented Battle Born GC3 batteries and integrated components, the system has been in active use across varying marine environments, supporting air conditioning, refrigeration, hot water, and other hotel loads. Its proven performance and reliability led World Cat to expand its use of Battle Born Batteries into larger models.

The new World Cat 400DC-X Island is the company’s latest flagship dual-console model, designed for premium comfort and offshore performance. Building on customer demand for more capable onboard systems, the 400DC-X Island now integrates a 540Ah lithium ship’s power system with a dedicated AC inverter.

“Battle Born Batteries have performed exceptionally well in real-world use, and our customers appreciate the reliability and convenience they provide,” said Rick Martin, materials manager at World Cat. “After seeing the system in operation on the 325 DC, bringing Battle Born Batteries forward as standard equipment on the new 400DC-X Island was a clear step. Dragonfly Energy has been an outstanding engineering partner.”

“Earning World Cat’s continued trust is a significant milestone for our marine OEM efforts,” said Wade Seaburg, chief commercial officer at Dragonfly Energy. “We believe their decision to adopt Battle Born Batteries as standard equipment on their 400DCX-Island reflects the proven reliability and long-term performance of our lithium power systems.”

The expansion strengthens Dragonfly Energy’s presence in the marine OEM market and underscores the growing demand for lithium power solutions that deliver long service life, consistent output, and reduced maintenance for both recreational and commercial boaters.
