Battery Quality Control for After-sale

All QH batteries in the package have a high degree of consistency. In a group, each cell has after-sales service for quality control. Your own electronic code (ID number), assuming that one cell in the package was damaged in a few years, we can provide customers with exactly the same cell to replace the damaged cell (same voltage, capacity, impedance, etc.) To ensure that all the cells in this package have a very high consistency. Melsen has a strong system for this job.
