leagend to Spotlight Integrated Supercap Starting Technology at AAPEX 2026

LAS VEGAS, MI, UNITED STATES — At AAPEX 2026, leagend will present the leagend Supercap Jump Starter Series at Booth V7315 on Level 2 of The Venetian Expo. The permanently installed system works with the vehicle's original battery to share engine-starting loads, while intelligent operating modes and app-based monitoring support day-to-day vehicle use.

Designed to become an integrated part of the vehicle's starting system, the leagend Supercap Jump Starter Series can participate in everyday starts and take on part of the high-current cranking demand. This reduces the load on the original battery, while automatic control manages the system according to vehicle conditions. The same installed system also provides a manual Forced Start function for more demanding starting situations.

As a top manufacturer in the battery testing and monitoring industry, leagend will meet with distributors, battery and parts businesses, service providers and automotive brands at the show. Discussions will cover vehicle applications, winter operating requirements, product distribution, private-label programs and OEM/ODM development.

Sharing the Load During Everyday Starting: Engine cranking requires a high current over a short period. With the leagend Supercap Jump Starter Series, the original vehicle battery and the Supercap unit work together to meet that demand. The unit takes on part of the cranking load, reducing the current that the original battery needs to supply during a supported start. Once installed, the unit remains physically connected to the vehicle battery. Its control electronics detect starting events and manage operation automatically, allowing it to share the load during normal use as well as under difficult starting conditions. Its contribution depends on the vehicle's condition and the energy available in the supercapacitors. The unit stores electrical energy in supercapacitors rather than an internal chemical battery. It can draw usable energy from the vehicle battery over time and release that energy rapidly during cranking. The system manages its own charging and standby operation, replenishing the capacitor bank when required.

Intelligent Operation From Starting to Driving: After installation and the first charge, AI Self-Learning Mode observes battery voltage and cranking behavior during the first few starts. It establishes a vehicle-specific baseline and uses that information to determine when to engage starting assistance. The driver continues to start the vehicle normally while the system learns and operates in the background. If a weak battery cannot supply enough energy to replenish the supercapacitors, an external Type-C power source provides another charging option. Once sufficient energy is stored, Forced Start Mode allows manual discharge through the device or smart app, following the product instructions. Drive Mode serves a different purpose after the engine is running. When enabled, it uses the supercapacitor bank as a short-duration energy buffer for brief voltage fluctuations and sudden electrical loads. The system disconnects this discharge path when the engine is switched off. Winter is a demanding application for the starting function. A cold battery can have less power available while the engine requires more effort to crank. By taking on part of this current demand, the leagend Supercap Jump Starter Series reduces the starting load placed on the original battery. The leagend Supercap Jump Starter Series is designed to operate from -40°C to 80°C.

Turning Starting Data Into Useful Service Information: The smart app connects these operating functions with information users can review. Through Bluetooth, it provides access to battery voltage, Supercap status, device temperature, starting and discharge data, historical records and alerts for unusual conditions. For workshops and battery specialists, these records provide information that can support customer discussions and guide further battery or electrical-system checks. For fleet maintenance personnel, each installation combines everyday starting-load sharing with battery and device information for an individual vehicle.

Matching the Series to Aftermarket Applications: The leagend JS200, leagend JS300 and leagend JS400 cover suitable 12V vehicle applications, while the leagend JS600 addresses suitable 24V commercial vehicle applications. Selection depends on the vehicle and its starting requirements. Distributors and importers can discuss models for the vehicle categories and markets they serve. Workshops and battery retailers can explore installation alongside battery testing and electrical-system services. For automotive brands, discussions can extend to private-label programs, packaging, functions and software requirements.

Engineering Experience Behind the Product: Founded in 2005, leagend has developed its business around battery testing, battery monitoring and automotive electronics. The leagend Supercap Jump Starter Series draws on that background in battery-related algorithms, electronic control, product engineering and manufacturing. The company's broader portfolio includes professional battery testers, battery monitors, smart battery chargers, OBD II diagnostic tools and thermal imaging solutions.
