Assembly process of lithium iron phosphate battery pack:

　　1. Choose suitable batteries, and match the capacity, voltage, and internal resistance of the batteries before assembly.

　　2. Calculate the distance and cut the insulation board.

　　3. Fix the battery pack with flange nuts.

　　4. Connect the voltage collection line (equalization line) and solder the line.

　　5. Use easy-curing insulating silica gel to fix.

　　6. Place the protection board PCM, which is the core component of lithium battery protection.

　　7. Use an insulating board to fix the entire battery pack, and then encapsulate it with nylon tape.

　　8. The battery is packaged as a whole, and the battery and protection board are fixed.

　　9. The power line adopts silicone line. Because it is a lithium iron phosphate battery, the weight is half of the lead-acid battery of the same specification.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries and are the first choice in the energy storage industry.

　　Advantages of lithium iron phosphate batteries:

　　1. Small size and light weight. The volume of the lithium iron phosphate battery is 1/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.

　　2. The cycle life of lithium iron phosphate batteries is 2000-4000 times, while that of traditional lead-acid batteries is only 500-900 times.

　　3. Good high-temperature performance: The thermal peak value of lithium iron phosphate battery can reach 350℃-500℃, and that of lead-acid battery is only about 200℃.

　　4. High-rate discharge: The discharge rate of lithium iron phosphate batteries can still reach 90% at a discharge rate of 5C.

　　5. Fast charging: Lithium batteries can be charged and discharged quickly at high current 2C, but lead-acid batteries have no such performance.

　　6. Eco-friendly: Lithium iron phosphate batteries are environmentally friendly batteries.

　　7. Memory effect: The shortcomings of lead-acid batteries, lithium iron phosphate batteries do not have this phenomenon.
