25.6V 320Ah Truck RV Auxiliary Battery - 4G+Bluetooth Smart Monitoring

Core Performance Highlights

1. Ultra-Large Capacity & Extended Endurance: Boasting a nominal voltage of 25.6V and total energy of 8.19kWh, a single full charge can power cab air conditioners, refrigerators, on-board office equipment, and other devices continuously for 35-38 hours, meeting the 10-12 hour auxiliary power needs of overseas truck drivers. It saves $3,500-$4,000 in annual fuel costs per vehicle. Supporting 80% DOD deep cycle discharge, it eliminates the risk of "sudden power drop" during long-haul transportation.
2. All-Climate Adaptation & Extreme Weather Resistance: With a wide operating temperature range of -30℃~65℃, it features a built-in intelligent heating system and multi-channel heat dissipation. It maintains over 90% capacity in frigid regions and avoids swelling or thermal runaway in high-temperature environments, covering full regional operations overseas from frigid zones to subtropical areas.
3. Compliant Safety & Multiple Certifications: Certified by UN 38.3, UL 1642, CE, FCC. Equipped with an intelligent BMS, it provides multiple protections against overcharging, over-discharging, short circuits, etc. With zero leakage and zero volatilization, it is suitable for closed cabs and cold chain scenarios.
4. Long Lifespan & Low Maintenance for Cost Reduction: With a cycle life of ≥4,500 times, it can be used normally for 12-15 years, 5-6 times longer than lead-acid batteries. Weighing only 75kg, it is 50% lighter than equivalent lead-acid batteries. The maintenance-free design reduces the total lifecycle maintenance cost by over 90%.

Exclusive Advantages for Overseas Markets

1. Intelligent Management & Fleet Compatibility: Standard-equipped with 4G + Bluetooth dual-mode communication, it is compatible with mainstream overseas fleet management platforms. Supporting remote monitoring, multi-language APP, and OTA upgrades, it meets the needs of digital management.
2. Plug-and-Play & Easy Installation: Its size fits standard truck battery compartments overseas. With a standard SAE J1939 interface, it seamlessly replaces lead-acid batteries without modifying the vehicle body. Boasting an IP67 protection rating, it resists rain, snow, and dust erosion.
3. Eco-Compliance & Policy Adaptation: Free of heavy metal pollution, it reduces carbon emissions by over 65% throughout its lifecycle.
4. Heavy-Duty Design & High-Load Adaptation: With a maximum continuous current of 300A and peak current of 900A, it supports the simultaneous operation of high-power equipment such as cold chain refrigeration and heavy-duty auxiliary air conditioners. Passing the ISO 12405 vibration test, it is suitable for complex road conditions.
