Q How to strictly control battery safety and quality?
A Safety testing is the most important part of our batteries quality test,extreme condition testing such as overcharging, overdischarging, short circuit, needle puncture, and high temperature (such as 85℃ storage).
Capacity Test: Verify whether the actual capacity meets the nominal value through charge and discharge cycles.
Cycle life test : ≥ 80% after 2000 cycles.
Pass CE, UL, Rohs,TUV, MSDS, UN38.3 on the basis of ISO9001 management system.

Q What’s the good way to make batteries in group keep best performance?
A Consistency screening is firstly done before batteries are divided into group.
-Eliminate cells with significant differences in voltage, internal resistance, and capacity (such as pairing within ± 1%) through capacitive devices.
-Using Dynamic Parameter Grouping (DVA) to match individual cells within the battery pack.

Q How to get long the usage life through measures and maintenance?
A 1. Optimize charge and discharge management
-Avoid deep discharge (for example, lithium-ion batteries are recommended to maintain a range of 20% to 80% power).
-Use intelligent BMS (battery management system) to control the charging cutoff voltage (such as ternary lithium battery ≤ 4.2V/single cell).
-Do not charge at high temperature (>45℃) or low temperature (<0℃).
2. Temperature control
-Install a heat dissipation system (air cooling/liquid cooling) to maintain the operating temperature between 15 and 35℃.
-Avoid heating caused by long-term high rate discharge (e.g.>1C).
3. Regular maintenance and monitoring
-Balanced charging: BMS regularly calibrates the difference in individual voltages (e.g., passive/active balancing).
-Storage advice: Keep 50% power when not in use for a long time, and recharge every 3 months.
-Monitor aging signs: consider replacement when capacity attenuation is greater than 20% or internal resistance increase is greater than 30%.

Q How long does it take to provide a customized solution exclusively?
A It depends on the complexity of the customized requirements. If it only involves design modifications or simple functionality additions, we can usually provide a design solution within one to two weeks. If it involves the modification of electronic components, it may take three to four weeks to complete the design solution.

Q Are there the same storage voltages and plugs in all places?
A The voltage and plug are not the same in different countries and regions. Typical national and regional socket standards: U.S., European, Japanese, British, Australian, South African and universal. Common voltage: 100V-120V (low voltage), 220V-240V (high voltage).
