1. Product Basic Information

2. Core Performance Parameters (Detailed Description)

• Nominal Voltage: 6.4V, which is the standard nominal voltage of the 32140F LiFePO₄ battery pack, providing stable voltage output during charging and discharging cycles. The voltage fluctuation is small, and there is no obvious voltage drop during continuous discharge, which ensures the stable operation of the connected equipment and avoids equipment failure caused by voltage instability.
• Nominal Capacity: 15Ah, which refers to the actual available capacity of the battery pack under standard operating conditions (25℃, 0.5C constant current discharge). The capacity retention rate is high: after 1000 charge-discharge cycles, the capacity retention rate is not less than 80%; after 2000 cycles, the capacity retention rate is still not less than 70%, which is far superior to traditional lead-acid batteries and ordinary lithium-ion batteries, and can meet the long-term use needs of equipment.
• Physical Specifications: The overall dimensions of the battery pack are 34×68×145mm (length × width × height), with a compact structure and reasonable size, which is suitable for installation in intelligent monitoring equipment, UPS power supplies, rail transit auxiliary equipment and other devices with limited installation space. The weight is moderate, which does not increase the overall load of the equipment, and is convenient for transportation and installation.
• Temperature Adaptability: The charging temperature range is 0～45℃, and the discharging temperature range is -20～60℃, which has excellent wide-temperature adaptation performance. It can work normally in low-temperature environments such as cold regions and high-temperature environments such as outdoor summer, without obvious performance attenuation. Even in extreme temperature conditions (-20℃ or 60℃), the discharge capacity can still reach more than 75% of the nominal capacity, adapting to various complex working environments.
• Charge and Discharge Performance: The battery pack supports 0.3C-1C charging and 0.5C-2C discharging (customizable according to demand). The charging speed is moderate, and it can be fully charged within 2-3 hours under 1C charging condition; the discharge performance is stable, and it can provide continuous discharge current to meet the power demand of medium-power equipment such as intelligent monitoring cameras and UPS backup power. It has no memory effect, and can be charged at any time without discharging first, which is convenient for daily use and maintenance.
• Safety Performance: As a LiFePO₄ battery pack, it has inherent safety advantages: it does not catch fire, explode or leak under extreme conditions such as overcharge, overdischarge, short circuit, extrusion and puncture. The built-in BMS (Battery Management System) can real-time monitor the voltage, current and temperature of each battery cell, and automatically cut off the circuit when an abnormal situation occurs (such as overcharge, overdischarge, overcurrent, overtemperature), effectively protecting the battery pack and the connected equipment, and eliminating potential safety hazards.

3. Product Core Features

• High Safety and Reliability: Adopting LiFePO₄ battery cell technology, which has the characteristics of non-combustible, non-explosive and low toxicity, and the built-in BMS provides comprehensive protection, ensuring safe operation in various complex environments and reducing the risk of safety accidents.
• Long Cycle Life: The cycle life can reach more than 2000 times, and the capacity retention rate is high after long-term use, which reduces the frequency of battery replacement, saves maintenance costs and improves the service life of the whole equipment.
• Stable Performance: The voltage and capacity output are stable, the self-discharge rate is low (≤3% per month under normal storage conditions), and it can maintain stable performance even after long-term standby, ensuring that the equipment can be started normally at any time.
• Wide Temperature Adaptation: It can work normally in the temperature range of -20～60℃, adapting to various harsh working environments such as cold, high temperature and humidity, and has strong environmental adaptability.
• Environmental Friendliness: LiFePO₄ battery does not contain heavy metals such as lead, mercury and cadmium, which is in line with international environmental protection standards, and can be recycled, reducing environmental pollution.
• Easy Installation and Maintenance: The compact size and lightweight design make installation convenient; there is no memory effect, and daily maintenance only needs regular inspection, without complex operation, which reduces the maintenance cost of equipment.

4. Applicable Scenarios (Detailed)

• Intelligent Monitoring: Suitable for outdoor intelligent monitoring cameras, monitoring hosts, security alarm equipment, etc. It can provide continuous and stable power supply for a long time, and adapt to outdoor low-temperature and high-temperature environments. Even in power outages, it can ensure the normal operation of monitoring equipment, realizing 24-hour uninterrupted monitoring.
• Rail Transit: Used in rail transit auxiliary equipment, such as train monitoring sensors, signal transmitters, emergency lighting equipment, etc. It has excellent vibration resistance and temperature adaptability, can withstand the vibration and temperature changes during train operation, and provides reliable backup power and working power for rail transit equipment, ensuring the safe operation of rail transit.
• UPS (Uninterruptible Power Supply): As a backup power supply for UPS equipment, it is suitable for small and medium-sized UPS systems, such as office UPS, industrial UPS, etc. When the main power supply is cut off, it can quickly switch to battery power supply, ensuring the normal operation of computers, servers, industrial control equipment and other devices, avoiding data loss and equipment damage caused by sudden power outages.
• Other Fields: It can also be used in portable electronic equipment, medical auxiliary equipment, solar energy storage systems, outdoor communication equipment and other fields that require medium capacity, high safety and long cycle life, providing flexible and reliable power solutions.

5. Usage and Maintenance Notes (Detailed and Practical)

• Charging Notes: Use a dedicated LiFePO₄ battery charger matching 6.4V, and do not use chargers of other specifications (such as lithium cobalt oxide battery chargers), so as to avoid overcharge, damage to the battery pack or safety hazards. The charging environment should be well-ventilated, dry and cool, and the charging temperature should be controlled within 0～45℃; do not charge in high-temperature, high-humidity or closed environments.
• Discharging Notes: Do not discharge the battery pack below the cut-off voltage (the recommended cut-off voltage is 5.2V), so as to avoid overdischarge damage to the battery cells and affect the service life. The discharge current should not exceed the maximum discharge current (2C), and avoid short-circuiting the positive and negative poles of the battery pack, which may cause overcurrent, overheating and damage to the battery pack.
• Installation Notes: When installing, ensure that the battery pack is fixed firmly to avoid vibration and collision during use, which may damage the battery cells or the BMS. Pay attention to the positive and negative poles of the battery pack, and do not connect them reversely, otherwise it will damage the battery pack and the connected equipment. The installation environment should be away from high-temperature heat sources, open flames and corrosive substances.
• Maintenance Notes: Regularly check the appearance of the battery pack, and if there is any damage, leakage, bulging or abnormal heating, stop using it immediately and replace it with a new battery pack. During long-term storage (more than 3 months), the battery pack should be charged to 50%-70% of the nominal capacity, stored in a cool, dry and well-ventilated environment (storage temperature: 0～30℃), and recharged every 3 months to maintain the activity of the battery cells.
• Other Notes: Do not disassemble, pierce, squeeze or burn the battery pack, which will cause battery leakage, short circuit and other safety hazards. Do not mix the battery pack with other types of batteries (such as lead-acid batteries, lithium cobalt oxide batteries) for use or charging. When replacing the battery pack, please select the same model, voltage and capacity to ensure compatibility with the equipment.
