Q1:Does the sending battery include BusBar connector and screws?

A1:Yes ,we ship the battery with the BusBar connector and screws.

Q2: How do I confirm the high quality of the product you sent me?

A2: No matter how many you order, We will test each battery before shipment to make sure it has the same voltage and resistance.

Q3:Will these batteries work with my existing Charge Controller/Inverter?

A3:Yes, but ideally you should have equipment that are compatible with Lithium/LiFePO4 cells.  It will work, and having a good quality BMS
will protect the cells, however having equipment suited to LiFePO4 cells means you will extend the lifespan of your cells.

Q4:How many cells do I need to become fully off-grid?

A4:The answer to this has several variables such as, how much energy are you consuming, the amount of charge your putting back into the battery bank and what is the peak current being drawn at anyone time.  The answer to all these questions will determine how many cells you need.  Best thing to do is (if possible) measure the amount of energy (Watts) you’re consuming over the typical day with a Watt Meter. This will give you an idea of how much energy you’re consuming and somewhat determine how many/type of cells you’ll need plus an idea of what solar/turbine/grid power source you’ll need to recharge your battery bank.

Q5:What is the life expectancy of a Lithium battery?

A5: The typical estimated life of the Lithium Iron Phosphate (LiFePO4) battery is 5-15 years, or 2000 to 8000 charge cycles. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.

Q6:Is the cells I bought balanced?

A6: 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.

Q7: The battery so heavy, will it damaged easily on the road?

A7: This is also a matter of great cocern to us. After long-term improvement and verification, our packaging is now very safe and reliable. When you open the package, you will definitely feel our sincerity.

Q8:I am a distributor. Can I cooperate with battery warehouse for a long time?

A8: Yes, Individual pricing for large scale projects and wholesale demands is available.

Q9:Why hasn't my UPS/DHL/GLS or Fedex transportation number been updated?

A9: 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/DHL/GLS or FedEx. Once they pass the customs and update the transportation number.

Q10:Why I can't buy cells from your store?

A10: This is usually unable to provide accurate logistics prices for your country. If you have any demand, please feel free to contact us.
