Business experience: Entered the lithium-ion battery industry in 2010, engaged in the production and manufacturing of lithium-ion batteries and the R&D and manufacturing of lithium-ion battery packs. Participate in the development of electric bicycle battery packs, forklift battery packs, and electric vehicle battery packs. Familiar with cylindrical battery pack technology, ternary and lithium iron phosphate battery technical details. If you have any questions about lithium-ion batteries, please contact me and I will provide you with detailed technical services.

FAQ

Q1. Can we put DIdifferentShould the lithium battery packs be connected in parallel or in series?
> Yes. Batteries can be placed in parallel or series by the customer. But there are a few tips we need to pay attention to:
1> Please ensure that the voltage of each battery is the same before parallel connection. If they are not the same, they will be charged at the same rate.
2> Do not place discharged batteries in parallel with undischarged batteries. This may reduce the capacity of the entire battery pack.
3> If you want to concatenate, please inform us the target capacity of the whole package. We choose the appropriate BMS for each type of battery.
4> If you are not a professional in parallel and series batteries, please do not handle the battery by yourself, which may damage the battery or reduce the cycle life of the battery.

Q2. Can we connect different lithium iron phosphate battery packs in series ourselves?
> You can buy high voltage battery pack directly from us. We do not recommend connecting them in series yourself, as this may damage the battery or reduce the cycle life of the battery pack.

Q3. Does the battery pack contain a BMS?
> Yes, our battery pack includes BMS.

Q4. What is your warranty?
> Depending on the product, we provide 1~5 years warranty.

Q5: What are your payment terms?
> Wire transfer recommended, PayPal and Western Union accepted.
1>Sample order: Full payment after receiving PI.
2> Mass production orders: 30% down payment when receiving PI and 70% before shipment.

Q6. How to transport lithium battery pack?
> For sample orders or small battery packs, we can ship via Fedex, UPS, TNT, etc. express. If the whole package exceeds 100KG, it can be shipped by air or sea, sea shipping is cheaper.
