Parallax Power Supply Battery Chargers: Decades of RV Charging Innovation
When it comes to keeping your RV's battery healthy and your onboard electronics running smoothly, few names carry as much weight as Parallax Power Supply. A pioneer in the RV electrical industry with over 50 years of service and innovation, Parallax has built its reputation on one foundational promise: reliable, intelligent power delivered the right way — especially when it comes to battery charging.
Built on Three-Stage Charging Technology
The story of Parallax battery chargers starts with the science of multistage charging. Parallax units today are descendants of the original three-current stage converter/charger dating back to the early 1970s, and the companies the Parallax technology evolved from were among the very first adopters of the technology for RV use. Since their inception, solid-state converters manufactured by MagneTek™ and Parallax have used Bulk, Absorption, and Float current modes — or "stages" — to charge RV batteries at a rate designed to maintain and promote battery life and safety. This isn't a marketing gimmick; it's an engineering standard that Parallax helped establish for the entire industry.
TempAssure™: Adaptive Charging That Responds to Conditions
What truly sets Parallax battery chargers apart in today's competitive market is their patented TempAssure™ technology. Cutting-edge products and technology such as the TempAssure™ system (patented) ensure your RV model remains at the forefront by promoting RV quality and innovation. With the TempAssure™ system, Parallax charging systems charge RV batteries better than any other RV converter system manufactured today. By adapting charge rates to real-world temperature conditions, TempAssure™ helps prevent overcharging in heat and undercharging in cold — both common causes of premature battery failure.
ParaMode™ 4400 Series: Modular Charging for Modern RVers
For those looking for versatility and a forward-thinking design, the ParaMode™ 4400 Series represents Parallax's next generation of converter/chargers. Parallax introduces the next generation of electronic converter/chargers with the ParaMode™ 4400 Series, whose streamlined, modular design represents a bold new direction for deck-mount converters. The modular concept allows ParaMode™ to meet the growing needs of RVers while remaining space-efficient, constructed of rugged steel for long-term durability, and featuring a high-efficiency, temperature-controlled fan for reliability — producing ultra-clean, filtered DC power ideal for battery charging and powering today's sophisticated RV amenities.
Lithium Battery Compatibility
Parallax has also stepped up to meet the demands of the rapidly growing lithium battery market. The 4400LBU is a lithium battery charging module from Parallax Power, engineered for compatibility with lithium batteries to ensure efficient and safe charging and optimize the performance of your RV's energy storage. Key features include a 13.9V Float Mode for maintaining a full charge and a 4-hour charging cycle at 14.0 VDC, assembled in North America using US Steel.
Built in North America, Built to Last
Parallax products have always been made in North America and built with steel enclosures, just as residential and industrial electrical systems are today. Parallax Power Supply provides reliability with extensive cycle testing of all its products, and field reliability is further enhanced by innovative diagnostics and controls. Whether you're replacing an aging converter or upgrading to a smarter charging system for a lithium build, Parallax battery chargers offer a proven, trusted solution backed by more than half a century of RV electrical expertise.
