• Internal Resistance Test
  Measure internal resistance of cells and packs to ensure consistency and stability.
• Insulation & Dielectric Strength Test
  Verify insulation and dielectric strength to prevent leakage and short-circuit risks.
• BMS Function Test
  Ensure BMS correctly monitors voltage, temperature, SOC, and communication.
• Waterproof & Dustproof Test
  Conduct IP67/IP68 protection tests to ensure safe operation in harsh environments.
• Aging & Cycle Life Test
  Perform repeated charge-discharge cycles to evaluate long-term reliability.
• Final Quality Inspection
  After all tests pass, apply serial labels and issue a quality inspection report.

CTS lithium batteries undergo rigorous multiple tests before leaving the factory to ensure the safety, reliability, and consistency of each battery system, ensuring that each battery can be delivered to customers in a highly safe and high-performance state.
