                      Q1. Can I just try samples for the first order?

                      A: Yes, trail order is acceptable. we can sell just a few pcs for you to confirm the specifications of our products.


                      Q2. Can I put LiFePO4 battery pack in parallel or series by ourselves?

                      A: Yes, but the batteries should be in same voltage and capacity, or it will influence the cycle life of the battery

                      pack. Also, you should tell us and we will match them before delivery. Before handling the battery, checking

                      the voltage of each battery is necessary. there are few tips we need to pay attention;

                      No.1 Make sure the voltage of each battery are same before put in parallel. If they are not same, charge 

                      them to the same rate.

                      No.2 Don't not put discharged battery and undischarged battery in parallel. This may reduce the capacity 

                      of the whole battery pack.

                      No.3 Advise us the target capacity of the whole pack if you would like to put them in series. 

                      We will choose the suitable BMS for each battery.


                      Q3. What is your warranty?

                      A: We offer 2 years warranty for all of our battery pack. we ensure at least 2000 cycle life for the LiFePO4

                      battery pack, which means, after 2000@80% DOD, there will still around 60% capacity left. You can use it

                      for at least 5 years for normal 1 time charge and discharge every day.


                      Q4. How does QH Technology ship the LiFePo4 battery packs?

                      A: The goods can be picked up by your own forwarder. If there is no forwarder. Then we can ship the battery

                      packs. For sample order or small battery packs, we can ship by express through Fedex, UPS, TNT, DPD etc.

                      If whole parcel over 100KG,can ship by air or by sea, sea shipping is more economical.

                      Customer can tell us your nearest airport name or sea port name for QH Technology sales person    

                      to check the best option for you.


                     Q5. Do you also have BMS and Chargers?

                     A:Yes, we do, if you need any to work with the battery cells , just advise us, we will provide  

                     them along with the lifepo4 battery cells to you.


                     Q6. How about the MOQ of the order?

                     A: No MOQ, feel free to contact us.


                     Q7: What is the lead time that you ship the goods after I pay?
                     A:3~7 days for sample order, 5-15 days for bulk order, mainly depends on order qty


                     Q8: Can I have discount price and service for wholesale?
                     A:Yes we are professional manufacturer and have favorable price and good service for wholesalers. 

                     Both OEM and ODM are warmly welcome .
