leagend Expands Battery Monitoring Technology into North America’s Marine Aftermarket

As a top battery testing and monitoring manufacturer, leagend brings 20+ years of expertise to North America’s marine market with its Battery Monitoring Series.

FORT LAUDERDALE, FL, UNITED STATES, September 18, 2026 /EINPresswire.com/ — As boats become increasingly dependent on onboard electrical systems, battery management is moving beyond periodic inspection. For marine businesses, understanding battery conditions during operation, storage and seasonal use is becoming an increasingly important part of battery service and maintenance.
leagend is responding to this shift by introducing its Battery Monitoring Series to the North American marine aftermarket. Developed around high monitoring accuracy, reliable long-term recording and ultra-low power consumption, the series is designed to provide continuous visibility into battery conditions rather than a single reading at the time of inspection.
For marine distributors, battery specialists, boat dealers, service organizations and equipment brands, the rollout introduces a connected battery-monitoring category that can complement existing battery, charging and electrical product portfolios.

Turning Battery Monitoring R&D into Marine Applications
Marine applications place distinctive demands on battery monitoring.
Boats may remain docked or stored for extended periods, while onboard electrical equipment can continue to affect battery conditions between trips. Professional battery testing remains important for evaluating a battery at a specific point in time, but it does not show what has happened during the intervals between inspections.
The leagend Battery Monitoring Series is designed to address that gap.
Continuous recording provides a history of battery behavior, while accurate monitoring helps ensure that the recorded information remains meaningful. Ultra-low power consumption is equally important for a device intended to stay connected over long periods with minimal additional demand on the battery.
Together, these capabilities provide a practical way to maintain battery visibility during operation, storage and seasonal use.

leagend Battery Monitoring Series: Built for Different Market Demands
Battery monitoring has been one of leagend’s established technology areas for more than a decade.
The product family includes leagend BM6 (12V battery applications) and leagend BM7 (6V/12V/24V battery applications). leagend BM6 addresses mainstream 12V monitoring requirements, while leagend BM7 extends the platform across a broader range of battery systems and applications, including boats.
Different models allow distributors and professional customers to address different voltage systems and application requirements within the same product family.
Across the range, the focus remains consistent: accurate monitoring, long-term data recording and ultra-low power consumption.
Rather than treating battery monitoring as a simple voltage-reading function, leagend has developed the series around the requirements of continuous connected use. This reflects the company’s broader capabilities in battery technology, electronic hardware, embedded systems, intelligent algorithms and connected applications.

More Than a Battery Monitor
The commercial relevance of the leagend Battery Monitoring Series extends beyond the product itself.
For marine service companies and electrical specialists, historical battery information can complement conventional testing and maintenance by providing visibility into what happened between service visits.
For boat dealers and service networks, monitoring can be incorporated into maintenance, seasonal-storage and customer-support programs.
For battery distributors and marine equipment companies, the series adds a connected technology category alongside batteries, chargers and electrical accessories already sold through established channels.
OEM and private-label companies can also draw on leagend’s engineering and manufacturing capabilities to develop products around their own brands, customer groups and market strategies.
In this context, battery monitoring becomes part of a broader marine battery-management offering rather than an isolated electronic accessory.

Built on a Broad Battery and Automotive Electronics Portfolio
The leagend Battery Monitoring Series is supported by a wider technology portfolio developed over more than two decades.

leagend Battery Testers
Battery testing is one of leagend’s longest-established technology areas. Developed around the company’s battery testing technologies and algorithms, the leagend Battery Tester Series focuses on high-precision battery testing, providing professional users with precise information for evaluating battery condition and starting performance.

leagend Battery Monitoring
The leagend Battery Monitoring Series extends that expertise into continuous connected applications, combining high measurement accuracy with ultra-low power consumption for reliable long-term battery monitoring and recording.

leagend Thermal Imaging Technology
The leagend Thermal Imaging Technology provides thermal visibility for automotive, electrical and mechanical inspection, supporting diagnostic and preventive-maintenance applications.

leagend SuperCap Jump Starters
The leagend SuperCap Jump Starter Series takes a different approach to the conventional portable jump starter. Instead of relying on an internal chemical battery that must be periodically recharged and maintained, the series uses a battery-free supercapacitor architecture designed for permanent vehicle installation.
The system remains connected to the vehicle and combines ultra-low power consumption and an extremely long product lifespan with functions including Forced Start Mode and AI Self-Learning Mode. Its design also helps reduce the high-current starting load placed on the vehicle battery, supporting longer battery service life while providing always-ready starting assistance.
The range includes models for different vehicle requirements. leagend JS300 is designed for most 12V passenger vehicles and SUVs up to approximately 3.5L; leagend JS400 serves larger-displacement, higher-load and performance applications; and leagend JS600 is developed for 24V commercial vehicles, trucks, buses and heavy equipment.
Together, these technologies show how leagend has expanded from individual battery products into a broader portfolio covering testing, monitoring, charging, diagnostics, thermal inspection and starting assistance.
