FAQ
Q1. Can Shenzhen Lithium Valley Technology Co.,Ltd. ship battery out of China?
R1: Yes, we can ship to any country out of China, you can tell us your address to check.
Q2. How does Shenzhen Lithium Valley Technology Co.,Ltd. ship the LiFePo4 battery packs?
R2: For sample order or small battery packs, we can ship by express through Fedex, UPS, TNT etc. If whole parcel over 100KG, can ship by air or by sea, sea shipping is more cheaper. Customer can tell your nearest airport name and sea port name for Lithium Valley sales person to check the best option for you.
Q3. Can we put different LiFePO4 battery pack in parallel or series by ourself?
R3: Yes. The battery can be put in parallel or series by customers. But there are few tips we need to pay attention;
1> Make sure the voltage of each battery are same before put inparallel. If they are not same, charge them to the same rate.
2> Don't not put discharged battery and undischarged battery in parallel. This may reduce the capacity of the whole battery pack.
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.
4> If you are not professional in parallel and series batteries, please don't handle the battery by yourself.
It may cause danger and hurt the cycle life of battery.
Q4. Can we put different LiFePO4 battery pack in series by ourself?
R4: You can buy big voltage directly from us. We suggest do not out them in series by yourself, it will hurt the cycle life of the
pack.
Q5. Does your battery pack include BMS? Can we use it for car?
R5: Yes, our battery pack include BMS, you can use it for low speed car only or aux. power for standard car. Do not use it for
standard car directly, that will need more complex design BMS for the pack.
Q6. What is your warranty?
R6: We offer 2 years warranty for all 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% capacityt left. You can use it for at least 5 years for normal 1 time
charge and discharge everyday.
