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
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
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
