FAQ

Q1. How do we ensure stringent control over battery safety and quality?

Safety Testingis integral to our battery quality assurance, including extreme condition tests like overcharging, overdischarging, short circuits, needle puncture, and high-temperature storage at 85ºC.
Capacity Test:We ensure the actual battery capacity matches the nominal value via rigorous charge and discharge cycles.
Cycle Life Test:Our batteries retain ≥ 80% capacity even after 2000 cycles.
Certified under ISO9001, our products meet CE, UL, RoHS, TUV, MSDS, and UN38.3 standards.

Q2. How to maintain peak battery group performance optimally?
Consistency Screeningis a preliminary step before grouping batteries.
- We remove cells with significant variancesin voltage, resistance, and capacity(e.g., pairing within ± 1%) using capacitive devices.
- UsingDynamic Voltage Adjustment (DVA)to synchronize cells within the battery pack.

of batteries shipped toover 90 countries globally.

Q3: How can we extend battery lifespan with proper measures?

Q4: What are your strengths, export experience, and use cases?

1. Optimize charging and discharging
-To prolong battery life, avoid deep discharges. Maintain lithium-ion batteries between 20%-80%.
-Use a Battery Management System (BMS) to control charging voltage. Ensure ternary lithium cells stay under 4.2V.
-Avoid charging in extreme temperatures. Do not exceed 45ºC or drop below 0ºC.
2. Temperature management
-Install a cooling system to keep temperature between 15ºC and 35ºC.
-Prevent overheating from high-rate discharges above 1C.
3. Regular maintenance and monitoring
-Engage in balanced charging: Regularly calibrate voltage differences with passive or active techniques.
-For storage, keep 50% power. Recharge every three months to preserve battery integrity.
-Monitor for aging signs. Replace if capacity drops over 20% or resistance increases over 30%.
