3.2V 230ah Lithium Ion Battery LFP Electric Power Systems Use

(1)Standard Charge:

Standard charging is to charge the battery with a constant current of 115.0A to 3.65V under the condition of an ambient temperature of 25ºC±2ºC, and then transfer to constant voltage charging at 3.65V until the charging current is less than or equal to 11.5A, and rest for 30min

(2)Standard Discharge:

Standard discharge is to discharge the battery at a constant current of 230.0A at an ambient temperature of 25°C± 2°C, discharge until the voltage reaches 2.5V, and rest for 30 minutes.

The capacity calibration is to charge the cell at a constant current of 173.0A to 3.65V under the condition of an ambient temperature of 25ºC±2ºC, and then transfer to constant voltage charging at 3.65V until the charging current is less than or equal to 8.65A, rest for 30 minutes, and then discharge according to the 3.6 standard discharge. Repeat the standard charging mode and standard discharging mode 5 times, the average discharge capacity of the last 3 times is the 1C discharge capacity, the recorded discharge capacity is the calibrated capacity C0, and the average discharge energy of the last 3 times is the 1C discharge energy. Record the discharge energy as the calibration energy E0.

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 or 2000 to 8000 charge cycles. One charge cycle
is a period of use from fully charged, to fully discharged, and fully recharged again.

Q: If I want to charge a solar LiFePO4/Lithium Ion battery, which already has PCB, would a normal SLA controller work fine?
A: For LiFePO4 / Lithium-Ion battery, we always recommend using the LiFePO4/Lithium-Ion solar controller. Especially if you are using the battery
as UPS (backup 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 the battery warehouse for a long time?
A: Yes, Individual pricing for large scale projects and wholesale demand is available

Q: Why hasn't my ups or FedEx transportation number been updated?
A: This is normal, 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.

Q: Are 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
