72V 120Ah Lithium Iron Phosphate Battery – Balanced High Voltage and Long-Lasting Energy
Product Overview
The 72V 120Ah LiFePO4 battery is designed for medium and large electric vehicles as well as high-performance energy storage systems. With its high-voltage platform and large capacity, it delivers both strong output and extended run time. The total energy capacity reaches 9.21kWh, with a continuous discharge current over 150A and peak current up to 425A, offering the perfect balance between power and stability.
Built with automotive-grade lithium iron phosphate cells and a smart BMS system, it combines powerful performance with long cycle life and enhanced safety.
Key Advantages of 72V 120Ah Lithium Battery Pack
1. Strong Power Output
The combination of a 72V high-voltage platform and 120Ah capacity enables continuous discharge over 150A with peaks at 425A. On a 30% slope, it can smoothly start a 1.5-ton vehicle, delivering power on par with a 2.0T gas engine. Even fully loaded at 2000kg, it maintains climbing speeds of 80km/h. Acceleration from 0–50km/h takes only 4.2 seconds, 15% faster than same-capacity NMC batteries.
Dynamic load simulation tests show that even at 50% SOC, this battery outputs 5.2kW peak power, making it ideal for electric tricycles, sightseeing shuttles, and vehicles requiring frequent stop-and-go performance.
2. Excellent Cycle Life
For commercial users, the real concern is long-term cost, not just the upfront price. Using automotive-grade LiFePO4 cells, the cycle life exceeds 4,000 cycles, translating to over 8 years of reliable use in most applications. At one cycle per day, that’s 10.9 years of service life—six times longer than traditional lead-acid batteries.
In real fleet operations, after 3 years, capacity retention is still above 85%, covering 150,000 km mileage on a single pack. Compared to traditional batteries, this reduces replacement by three times, saving over $1,000 in costs. Combined with its maintenance-free design—no refilling, balancing, or specialized care required—this further lowers labor and operational expenses.
3. High Safety Protection with LiFePO4 Cells
Safety is the baseline for any commercial power battery. LiFePO4 chemistry has exceptional thermal stability, resisting decomposition and combustion even at 500–600℃, eliminating thermal runaway risks. The battery has passed nail penetration, crush, drop, and oven tests, and meets UN38.3, CE, and UL certifications.
The smart BMS system monitors voltage, current, and temperature in real time, with protection against overcharge, over-discharge, short circuit, and overheating. Thanks to the natural thermal stability of LiFePO4, the battery performs safely even under heavy load or in harsh environments. It’s especially suited for warehouses, public areas, and hot, humid climates, ensuring both equipment and people remain safe.
4. High Efficiency & Low Maintenance
-
Fast charging: Supports up to 2C charging, reaching full capacity in 3 hours (vs. 8 hours for lead-acid).
-
Stable discharge: Maintains voltage above 68V throughout the cycle, with no power drop at the end.
-
Low maintenance: No regular refilling or balancing required. At -20℃, it still delivers 80% capacity.
5. Scalability & Connectivity
Modern fleets need more than just power—they need connectivity and monitoring. This battery supports CAN bus, RS485, or Bluetooth communication, integrating seamlessly with fleet management systems, remote monitoring platforms, or energy dispatch centers. SOC, voltage, temperature, and fault codes can be uploaded in real time.
Optional low-temperature heating module ensures winter charging efficiency down to -20℃. The IP67 waterproof and dustproof housing protects against rain, snow, sand, and humidity, making it ready for rugged environments. With expansion interfaces built-in, it is future-proof for smart fleet management and energy optimization.
6. OEM Customization & Bulk Supply
Every application has unique requirements for battery size, connectors, and communication protocols. We provide full OEM/ODM customization, tailoring dimensions, mounting, and interfaces (Anderson, XT90, MC4, etc.). Supports CAN2.0B, Modbus, and other industrial communication standards.
Options include IP67 protection, explosion-proof design, and shock resistance, meeting the demands of mining, marine, and special equipment. Small pilot orders (1–10 units) and mass production (1000+ units) are supported, with factory-direct supply for stable quality and reliable lead times.
