TMC, Mastervolt Develop Lithium Ion System 


Mastervolt, a leader in marine and RV power conversion, and Thor Motor Coach recently announced a new custom system for onboard power technology. Power Products System Integrators (PPSI) collaborated with Thor engineers to develop a new system designed to provide grid-quality power without the need for a generator or AC source. 

The Mastervolt MLI Ultra Li-Ion batteries provide a total of 11,000 watts. The integrated battery management system monitors the individual battery cells to optimize performance. It can be directly integrated into NMEA 2000 or RV-C networks, so key battery data can be viewed on displays that are on the same network. An embedded data recorder tracks and records charge and discharge cycles over the life of the battery. 

“The new MLI Ultra batteries from Mastervolt truly represent an evolution and new level of performance in Li-Ion technology,” said Reese Bischoff, national sales manager for Power Products. “We felt that Thor was an ideal launch partner for this technology in the Class B category because of the sophisticated electronics and loads that are built into Thor Motor Coaches.” 

The Mastervolt CombiMaster inverter/charger provides a pure sine AC power source to operate all sensitive electronics on the coach. At the same time, it charges the Li-Ion batteries when plugged into an AC source. When a dedicated AC source is not available, batteries are charged via a 280-amp alternator and Alpha Pro III regulator. Key data of the entire system is readily viewable on the EasyView display screen. All of the components communicate on the same network, so they are constantly sharing data and optimizing the system for performance and safety, according to the company. All of the components in the Mastervolt system come with a 5-year warranty. 

“We pride ourselves in being industry leaders when it comes to introducing cutting edge technologies,” said Jon Krider, VP of product development and marketing at Thor Motor Coach. “We are excited to be partnering with Mastervolt, as their technology aligns with our high standards.”
