71173 Battery Cell is big size prismatic aluminum shell lithium battery that uses lithium iron phosphate material. This battery cell is a energy type battery, supports continuous 1C charging and 1C discharge. The cycle life exceeds 6,000 times. We can also customize battery packs of various sizes and performances according to your needs.
71173 LiFePO4 batteries are commonly used in energy storage systems, power tools, electric two-wheelers, portable devices, and solar energy storage devices, etc. They are especially suitable for medium and large battery pack applications that require high energy density and long life.
Depending on the application requirements, the batteries can be assembled in series or parallel:
Series connection (such as 4S) to form a 12.8V battery pack, suitable for home energy storage or portable power devices.
Parallel connection is used to increase the total capacity and is suitable for long-term operation equipment.
Intelligent battery management system (BMS) is required during assembly to ensure the safety and performance of the battery pack.
The battery supports a continuous discharge rate of 0.5C, which can meet the application scenarios of lower power and is suitable for large and medium-sized energy storage battery systems.
Yes, the battery is suitable for working environments of -20°C to 60°C. Under lower or higher temperature conditions, its performance can be further optimized by configuring the temperature control system.
The assembled battery pack can support the following certifications:
Absolutely suitable. 71173 battery cells are very suitable for energy storage systems with their high energy density and long life. They support deep discharge and efficient charging and can be used in solar energy storage, portable energy storage and other scenarios.
Under normal use conditions, the battery cell can provide more than 6,000 charge and discharge cycles, and the service life can reach more than 8 years.
