FAQ
Q1: What is the fast charging performance of this cell?
A: At 25℃, it only takes 20 minutes to fast charge from 10% to 80% SOC. Corresponding charging rates are adapted to different temperature ranges, balancing charging efficiency and safety.
Q2: What is the cycle life of the cell?
A: At 25℃ (100%DOD), the SOH remains ≥80% after 3000 cycles; at 45℃ high temperature (100%DOD), the SOH is ≥80% after 1500 cycles, which greatly reduces the total life cycle cost.
Q3: What is the C-rate charge and discharge capability of the cell?
A: Maximum continuous discharge current: 4C; maximum pulse discharge current: 14.5C (10s). The 2C discharge capacity retention rate is ≥95% at 25℃, which can meet the demand for high-power instantaneous output.
Safety & Storage
Q4: What safety guarantees does this cell have?
A: It has passed a series of rigorous tests including overcharge, overdischarge, short circuit, extrusion, impact and low air pressure, complying with GB 38031-2020 and UN38.3-2021 standards. The test results show no explosion, no fire and no leakage.
Q5: What is the self-discharge rate of the cell, and what are the requirements for long-term storage?
A: At 25℃, the self-discharge rate is ≤3% when stored at 100% SOC for 28 days, and ≤2% when stored at 50% SOC. Unopened cells should be stored in a dry environment with a temperature of -10℃~30℃ and relative humidity ≤75%, and recharged every 2 months.
Q6: What are the internal resistance indicators of the cell?
A: At 25℃ and 50% SOC, the AC internal resistance is ≤1.1mΩ, and the DC internal resistance is 2.8mΩ (5C/10s). The low internal resistance design effectively reduces heat generation during charging and discharging and avoids the risk of thermal runaway.
Application & After-sales
Q7: Is the cell a genuine original factory product, and is there any quality assurance?
A: It is directly supplied by Hefei Gotion Hi-Tech with the original factory specification, complying with national power battery standards and without middlemen. We promise ten times compensation for fake products, and can provide actual photos for inspection before delivery.
Q8: What is the return and exchange policy for the cell?
A: The cell is a precision electronic component, and no return or exchange is available for non-quality issues. If there are quality problems such as unqualified capacity and abnormal internal resistance upon receipt, please provide a test report within 7 days, and we will provide free reissue or refund after verification.
Q0: Does the cell support modular assembly, and is technical support available?
A: The standardized cylindrical design is perfectly suitable for modular assembly. We provide professional technical consultation and one-on-one answers to questions about cell selection, grouping and application.
