Quality Inspection
Finished boat lithium batteries undergo a four-step quality inspection:
Appearance inspection
Verify pack dimensions, casing condition, welds, and internal connections/harnesses.
Performance test
Test charge-discharge current, voltage and resistance with professional equipment for compliant parameters.
Safety test
Conduct overcharge/over-discharge, short-circuit, temperature, impact, drop, extrusion tests; add salt spray and humidity tests for marine anti-corrosion and moisture resistance, ensuring stable performance in rated temperature range.
Service life test
Perform cycle charge-discharge and aging tests to verify standard cycle life and long-term performance stability.All tests ensure the battery's reliable and stable quality.
