FAQ

Q1.How to strictly control battery safety and quality?

Safety testing is crucial in our quality tests, including extreme condition assessments like overcharging, overdischarging, short circuit, needle puncture, and high-temperature storage at 85ºC.
Capacity Test: Verify the actual capacity against the nominal value via charge and discharge cycles.
Cycle life test: Endures 2000 cycles with ≥ 80% capacity retention.
Certified by CE, UL, Rohs, TUV, MSDS, UN38.3 under ISO9001 management.

Q2.Optimal group performance enhancement techniques?
Start with consistency screening prior to grouping batteries.
-Remove cells with notable differences in voltage, resistance, and capacity (pair within ±1%) using capacitive devices.
-Implement Dynamic Parameter Grouping (DVA) to synchronize cells in the battery pack.

s of batteries to over 90 countries, etc.

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

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

1. Optimize charge and discharge management
-Avoid deep discharge; maintain lithium-ion batteries between 20% and 80% power.
-Deploy intelligent BMS for cutoff voltage control (ternary lithium ≤ 4.2V/cell).
-Avoid charging in extreme temperatures (>45ºC or <0ºC).
2. Temperature control
-Install cooling systems (air/liquid) to keep temperatures between 15 and 35ºC.
-Avoid heat from prolonged high-rate discharge (e.g., >1C).
3. Regular maintenance and monitoring
-Balanced charging: BMS calibrates voltage differences (passive/active balancing).
-Storage tip: Maintain 50% charge when unused long-term; recharge every 3 months.
-Monitor aging: Replace if capacity drops >20% or resistance rises >30%.
