Mastervolt, manufacturer of power systems and components for the marine and RV markets, completed testing of its lithium-ion batteries with Testing Engineers International, the RV Industry Association approved test lab, to meet UL 1973 standards.

To be included in RV products, lithium-ion batteries must be listed by a third-party agency recognized by the RVIA. The UL1973 compliance confirms that Mastervolt lithium-ion batteries are compliant with all RVIA requirements.

Along with its ISO 9001 certification, the company said the new certification demonstrates a commitment to the highest standards of safety, quality and compliance in power manufacturing. Mastervolt is part of ASG-Advanced Systems Group, a subsidiary of Brunswick Corp.

“Continuous improvement and safety are the mainstays of our culture,” Mara White, Mastervolt senior product manager, said in a statement. “Meeting the UL 1973 standard is an important milestone. … As we continue to evolve our integrated power technology, maintaining critical standards is vital.”
