Product Overview
The HUAXING 32700 High-Temperature Edition is a specialized Lithium Iron Phosphate (LiFePO4) cell engineered for superior performance in elevated temperature environments. Delivering a reliable 6000mAh capacity at 3.2V, it excels where standard batteries falter, maintaining over 80% capacity after 1000 cycles at an extreme 70°C. Featuring robust steel casing and double safety protection, it is the optimal power core for small power mobility and industrial & commercial energy storage systems operating in demanding thermal conditions, ensuring longevity and safety where heat is a constant factor.
Unmatched Cycle Life Under Extreme Heat for Demanding Applications
This cell is specifically engineered to defy the primary enemy of battery life: heat. It delivers an industry-leading high-temperature cycle life, capable of over 1000 cycles at 70°C and 1500 cycles (A+ Grade) at 55°C while retaining ≥80% capacity. This exceptional performance ensures long-term reliability and reduces total cost of ownership for small power devices and energy storage systems that must operate continuously in hot climates, direct sunlight, or within enclosed spaces with poor ventilation.
Optimized Performance & Safety for Sustained High-Temperature Operation
Beyond longevity, the cell maintains robust operational integrity in the heat. It features remarkable high temperature performance with stable power delivery. The double safety protection system, including a vent tube and safety valve, is critical for managing internal pressure under thermal stress. This design, coupled with a pressure-resistant steel casing, provides an added layer of security for applications like outdoor energy storage cabinets or electric vehicles in tropical regions, where safety cannot be compromised.
Rigorously Verified Quality and Extended Service Life
Quality is proven through rigorous testing. The cell achieves an excellent room-temperature cycle life of 2500 cycles (A+ Grade). Its stability is further validated by high-temperature storage tests, showing ≥93% capacity retention after 10 days at 60°C. Manufactured under strict control, the A+ Grade cells offer top-tier consistency. This translates into dependable, maintenance-free performance for industrial and commercial energy storage (ESS), ensuring system uptime and durability over many years of service.

FAQ
Q1: What are the specific test conditions for the claimed 1000 cycles at 70°C, and how can we verify this data?
A1: Thank you for your question. This data is based on our rigorous internal testing under the following conditions: 70±2°C ambient temperature, 1C charge/discharge rate (CC/CV to 3.65V, discharge to 2.0V), with a capacity retention criterion of ≥80%. We are happy to provide a summary of the detailed test report for your technical team's review upon request.
Q2: For our application in a hot climate, how does the charging efficiency compare at high temperatures (e.g., 45-50°C) to room temperature?
A2: That's an excellent point for real-world application. While the standard charge rate is 1C, optimal long-term performance and efficiency are achieved within the recommended charging temperature range of 0°C to 45°C. For sustained operation above 45°C, we recommend consulting our engineering team to discuss potential charge current adjustments or thermal management strategies tailored to your specific pack design and environment.
