FAQ

Q1.How to strictly control battery safety and quality?

Safety testing is paramount in our quality tests, including extreme conditions like overcharging, overdischarging, short circuits, needle puncture, and high temperatures (up to 85ºC storage).
Capacity Test: Ensure actual capacity aligns with nominal values via charge and discharge cycles.
Cycle life test: Maintains ≥ 80% after 2000 cycles.
Certified by CE, UL, Rohs, TUV, MSDS, UN38.3 under ISO9001 management.

Q2.What's the best way to ensure batteries in a group perform optimally?
Consistency screening is initially performed before grouping batteries.
-Eliminate cells with notable differences in voltage, resistance, and capacity (such as pairing within ±1%) using capacitive devices.
-Employ Dynamic Parameter Grouping (DVA) to align individual cells in the battery pack.

Q3:How to extend usage life through measures and maintenance?

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

1.Optimize charging and discharging
-Avoid deep discharge (lithium-ion should ideally stay between 20% and 80%).
-Use an intelligent BMS to manage charging cutoff (e.g., ≤ 4.2V/cell for lithium).
-Avoid charging in extreme temperatures (>45ºC or <0ºC).
2. Temperature management
-Use cooling systems to maintain 15-35ºC operating temperature.
-Avoid overheating from prolonged high-rate discharge (e.g., >1C).
3. Routine maintenance and monitoring
-Balanced charging: BMS regularly adjusts voltage differences (e.g., passive/active).
-Storage tip: Maintain 50% power when idle, recharge every 3 months.
-Monitor for aging: Replace if capacity drops over 20% or resistance rises over 30%.
