After-sale Service 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.5. Factory and EquipmentBoruiis a pioneer in the lithium battery market and a unique lithium battery solution company. LiFePo4 and NMC(Li(NiCoMn)O2) are the major material. Borui is a is a high-tech enterprise in national key field, which is specialized in developing, producing, selling lithium polymer battery and battery pack, BMS, PACK, and high-quality and high-rate starting battery. The product application field range from EV to HEV, including bus, PCV, SUV, golf cart, city delivery vehicle, mail truck, electric garbage vehicle and so on. Borui Power is planning to launch a series of products which can provide power for electric vehicle and motorcycle.
