Part of factory view:
Waranty:
We give 1 year warranty. If the battery has problem coz of our quality issue, We will give replacement any time.
Q&a;A:
1. Q: How long to make the cargos?
A: Need 30day around if we dont have the stock of that model. Coz need strictly test and high teerature,high voltage life ageing as well in every single pc. That will takes a fixed date.
2. Q:How to start the cooperate?
A: Lets start with the sale orders. In 3-5days will be ready the sales, then you test.We make the standard according
the data sheet which we give.Once you confirm the quality, we can talk for further.
3. Q: What will be the packing?
A: We are using blister pallet packing in each battery pack. and then fold all packing in one ctn.
4. Q: Can the connectors be customized?
A: Yes, we can choose the right connector according your requirement.Or help to match your device
.
5 Q: Is OEM/ODM battery pack available?
A: Yes, OEM/ODM battery packs are warmly welcome. Professional engineers provide technical support.
6 Q: What information do you need to make a customized battery pack?
A: We need the details below:
1. Size of the battery pack you need in mm.
2. Capacity of the Battery pack.
3. Voltage of the battery pack.
4. Max discharge current.
5. Cable and connector types you need.
6. Casing and Terminals if required.
7. Any protection circuits you may need.
7 Q: How do you arrange shipment for batteries?
A: We have long-standing forwarder partner who arranges all our shipments to all countries. Although batteries are categorized as dangerous goods, you should rest assured that your cargo will be delivered through our experienced shipping partner(s).
8 Q: Do you have the documents required for battery shipments?
A: Yes, we have MSDS, UN38.3, etc. and other special files needed for shipments to some regions can also be secured.
