[How To Connection And Assemble]

As shown below, you can use a combination of batteries connected in series and parallel to get voltage levels of 12V, 24V, and 48V.Get creative to DIY and build your own battery packs for RV&Trailer/Vans/Campers,Boat,Yacht,Trolling Motor,Golf Cart,Electric Wheelchair,Truck,Home Solar Bank,etc.
1. Please balance the battery cells before assembly.
2. Install and connect the screws.
3. Fix the entire battery pack with an insulation board and wrap it with nylon tape.
4. Install the BMS!!!

*It is recommended that all screw assembly be done manually; It is not recommended to use electric tools since Electric tools have a torque peak that can easily damage the terminals of laser welding.

[Note]

That this model of battery is produced in a high-altitude plant, where nitrogen is injected during production. If there is a Slight bulge, this is normal and will not affect its normal performance. Please don't worry. This can be ameliorated by compression and multiple cycles.

[About Delivery Time]

The below provided transportation time is a general reference, excluding inspection or other exceptional circumstances like natural disasters or traffic.Thank you for your patience and kindly understanding.

Order ship from local overseas warehouse:If your order is shipped from a local overseas warehouse, the estimated transit time to most countries ranges from 2 to 14 business days.

[Precautions]

1.No matter what the charging model is, once the temperature of the cell is above the absolute charging temperature, charging should be stopped.

2.Customers should configure a BMS which is used for strictly monitoring, management and protection.

3.Properly connect the terminals of positive and negative of the batteries. The reversal charging is forbidden. If the polarity is reversed, the battery will be damaged and safety problem may occur.

4.If the batteries kept unused for a long time, it should be charged and discharged at the standard model every six months. Store the battery in the state of 30% SOC (voltage scope: 3.275V~3.305V).

5.AppearanceWithout break,distortion, contamination,leakage.

FAQ

Q:Where are the batteries shipped from and how soon can I receive them if I am in the EU?

A: We will ship for you from our local warehouse in Europe, we have a large number of new batteries in our warehouses in Poland and Germany, if you are in the EU, as we say on our details page, you can receive the batteries in around 7~15 days.

Q:Does the sending battery include BusBar connector and screws?

A: Yes ,we ship the battery with the BusBar connector and screws and enjoy 5 kinds of accessories as a gift for your Excellent DIY Pack.

Q:What is the life expectancy of a Lithium battery?

A: The typical estimated life of the Lithium Iron Phosphate (LiFePO4) battery is 5-15 years, the Grade A 320Ah batteries has over 8000 cycles life@25℃ after testing .One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.

Q:If I want to solar charge LiFePO4/Lithium Ion battery, which already has PCB, would a normal controller work fine?

A: For LiFePO4 / Lithium Ion battery, we always recommend to use LiFePO4/Lithium Ion solar controller. Especially if you are using the battery as UPS (back up power supply). The Lead Acid solar controller will constantly provide pulse current to the battery, in the long run, it might damage the PCB. So the PCB won't be able to protect the battery when it should be.

Q:I am a distributor. Can I cooperate with battery warehouse for a long time?

A: Yes,Individual pricing for large scale projects and wholesale demands is available.

Q:Why I can't buy cells from your store?

A: This is usually unable to provide accurate logistics prices for your country. If you have any demand, please feel free to contact us.

Q:Is the cells I bought balanced?

A: We know the importance of maintaining the consistency of each cell in the battery pack, so we will match and balance all cells to ensure that the internal resistance, voltage and capacity of cells are completely matched and balanced before delivery. This process is very necessary.

Q:Why hasn't my ups or Fedex transportation number been updated?

A: This is normal, because in countries with tariffs, our packages need to pass the customs of your country before they can be delivered to the local UPS or FedEx. Once they pass the customs and update the transportation number, you can usually receive the goods within 3-5 days.

⭐In addition, because the battery is prohibited product, many courier and logistics are unable to send, the arrival will indeed be slower, so please wait patiently after place an order. Can Not give us bad feedback due to the courier company or because of the courier service slow or other factors. open dispute will be unacceptable. Sorry for any inconvenience.

[Reminder]

DIY battery pack must get the cells balanced (same voltage) before assembly. Later if there happens don't know how to assembled or unbalanced assembly is not accepted refund. please consider before taking orders, place order means you have agreed. thank you for your cooperation!
