In scenarios such as urban short-distance distribution, urban and rural passenger transport, environmental sanitation operations, and agricultural transportation, electric rickshaws have become core transportation tools for people’s livelihood and grassroots operations due to their flexibility, low cost and zero-emission advantages. The performance, service life and safety of power batteries directly determine the operating efficiency and usage cost of vehicles. The 72V 150Ah lithium iron phosphate (LiFePO4) battery is a high-end customized power supply for medium and large-sized electric rickshaws. Relying on stable lithium battery chemical characteristics, large-capacity energy storage specifications and a comprehensive intelligent protection system, it completely solves the pain points of traditional lead-acid batteries such as short service life, virtual battery life, poor low-temperature resistance and easy bulging damage. It has become a mainstream upgraded power configuration for low-speed new-energy rickshaws, widely suitable for cargo rickshaws, passenger rickshaws, sanitation rickshaws and other models.

　　The 72V 150Ah LiFePO4 battery adopts a scientific voltage and capacity ratio, perfectly matching the power output requirements of electric rickshaws. The 72V high-voltage platform ensures strong power during vehicle starting, climbing and heavy-load operation, effectively avoiding weak power and insufficient climbing performance of low-voltage batteries. The 150Ah large-capacity reserve provides an ultra-long driving range of 150 to 170 kilometers under standard working conditions, fully meeting the needs of high-frequency and long-distance daily operation. Compared with lead-acid batteries of the same specification, this LiFePO4 battery boasts about three times higher energy density, smaller size and lighter weight under the same capacity. It effectively reduces vehicle body load and motor energy consumption, further improving the driving range and load capacity, and solving the drawbacks of bulky size and large space occupation of traditional batteries.

　　Ultra-long cycle life and low operation and maintenance costs are its core competitive advantages. Traditional lead-acid batteries only have 300 to 500 charge-discharge cycles and require frequent replacement every year, resulting in high maintenance costs. Adopting high-quality LiFePO4 cells with stable structure and strong attenuation resistance, the 72V 150Ah LiFePO4 battery achieves 3,000 to 3,500 cycles under standard working conditions, more than five times that of lead-acid batteries, and can operate stably for 5 to 8 years with normal use. Meanwhile, it features an extremely low self-discharge rate, slow power loss during static placement and no damage from long-term idle state, requiring no frequent supplementary charging. Although its initial procurement cost is higher, it eliminates frequent replacements in long-term use, greatly reducing the comprehensive cost of later operation and maintenance and parts replacement, with outstanding economic advantages.

　　Safety protection is a core indicator of power batteries and a key factor for LiFePO4 batteries replacing traditional batteries. The 72V 150Ah LiFePO4 battery is equipped with a dedicated BMS (Battery Management System), featuring seven core protection functions including over-charge, over-discharge, over-current, short circuit, high temperature, low temperature and over-voltage protection. It can real-time monitor cell voltage, temperature and current data, and automatically power off under abnormal working conditions to eliminate potential safety hazards. In addition, LiFePO4 materials have excellent thermal stability, high temperature resistance, non-combustion and non-explosion performance, as well as strong impact and puncture resistance, completely avoiding leakage, bulging and spontaneous combustion risks of lead-acid batteries. The overall sealed and waterproof shell provides dustproof, moisture-proof, vibration-resistant and wear-resistant performance, adapting to complex working conditions such as outdoor rain and snow, high and low temperatures, and bumpy roads to support all-weather operation.

　　This battery delivers outstanding adaptability and practicality in actual application scenarios. For urban express and fresh food delivery rickshaws that require high-frequency and uninterrupted operation, its ultra-long range, fast energy replenishment and long service life perfectly adapt to high-intensity working rhythms and eliminate shutdowns caused by power failure. For urban and rural short-distance passenger rickshaws with high requirements for power stability and safety, the high-voltage platform provides stable and smooth power output without stuttering, improving riding comfort. For agricultural and environmental sanitation electric rickshaws operating in complex environments, its excellent weather resistance and vibration resistance ensure stable power supply in complex field and road scenarios, maintaining consistent power output in extreme high and low temperatures.

　　With the standardization and new energy upgrading of the low-speed electric vehicle industry, power batteries with high safety, long service life and low energy consumption have become the mainstream development trend. Breaking the technical bottlenecks of traditional lead-acid batteries, the 72V 150Ah LiFePO4 electric rickshaw battery has become the preferred solution for vehicle power upgrading due to its comprehensive advantages of strong power, ultra-long range, high safety and low maintenance cost. It not only improves the operating efficiency and stability of low-speed transport vehicles, but also promotes the green and low-carbon transformation of short-distance transportation and urban-rural operation fields, providing solid technical and hardware support for the popularization and iteration of new-energy livelihood transportation vehicles.
