46140 LiFePO4 Cell Configuration

The battery pack uses 46140 cylindrical LiFePO4 cells arranged in a 16-series and 2-parallel configuration. This electrical architecture provides the required voltage and capacity for high-power off-road vehicle systems while maintaining a compact and practical battery structure.

The large cylindrical cell format provides a robust internal structure and effective heat dissipation. Its low internal resistance helps control heat generation during high-current operation, while the multi-tab/tabless cell design supports more efficient current collection and thermal management.

This configuration is particularly suitable for electric platforms that may experience frequent acceleration, variable loads, and demanding operating conditions.

Intelligent BMS for Battery Monitoring and Protection

An integrated intelligent Battery Management System is used to manage the battery pack during charging, discharging, and operation.

The BMS provides multiple protection functions, including:

• Overcharge protection

• Over-discharge protection

• Over-current protection

• Over-temperature protection

• Short-circuit protection

A high-precision fuel gauge allows key battery information to be monitored in real time. The system supports CAN, RS485, and Bluetooth communication, enabling battery data such as SOC, SOH, and individual cell voltage to be accessed through compatible vehicle dashboards, control systems, or mobile applications.

This intelligent monitoring architecture helps system developers obtain more detailed battery operating information during vehicle operation and maintenance.

Rugged Construction for Off-Road Applications

Off-road vehicles are exposed to conditions that can place additional mechanical and environmental demands on a battery pack. To address these requirements, the battery is constructed with a high-strength aluminum alloy housing and a reinforced internal anti-shock structure.

The internal assembly incorporates thermally conductive and flame-retardant potting material to improve structural stability and heat management. This construction helps the battery withstand vibration and impact during operation on uneven terrain.

The enclosure is designed to achieve an IP67 protection rating, providing resistance to dust ingress and temporary water immersion. This makes the pack suitable for demanding outdoor environments involving mud, water crossings, vibration, and significant temperature variations.

Technical Specifications

Charging and Discharging Performance

The recommended standard charging parameters are 58.4V charging voltage and 20A charging current, with the charging process ending at a 3A cut-off current.

For standard discharge operation, the specified discharge current is 60A, with the discharge cut-off voltage set at 36.8V. These parameters provide a defined operating range for system integration and battery management.

The actual battery application should be matched with the vehicle's electrical architecture, controller, charger, and operating requirements to ensure proper system compatibility.

Applications

The 51.2V 60Ah battery configuration can be adapted for a range of electric vehicles and outdoor equipment that require a rechargeable LiFePO4 power source.

Typical application areas include:

• Smart off-road 4WD vehicles

• ATVs and UTVs

• Electric off-road motorcycles

• Outdoor power equipment

• Other customized electric mobility platforms

Its combination of intelligent battery management, reinforced construction, and IP67 protection makes it suitable for vehicle projects where environmental durability and battery monitoring are important design considerations.
