Battery quality control for after-sale
All of Borui battery cells in a pack are with very high consistency.In a pack, each cell has its own sole electronic code(ID number) for quality control after-sale. Assume one cell in a pack is damaged in any reason after several years later, we could provide a exactly same cell to the client to replace this damaged one(same voltage, capacity, impedance,etc.), in order to make sure all of the cells in this pack with very high consistency. Borui has a strong system working for this.
