Battery quality control for after-sale
All of E-POW battery cells in a pack are with very high consistency.In a pack, each cell has its ownsole 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. E-POW has a strong system working for this.
