2.The charger should have a pre-charging system and the pre-charging function should be used to prevent abnormal high power charging after deep discharge. After long-term storage, When the cell voltage is lower than 2.75V (0%SOC), the cell must be pre-charged with a current lower than 0.1C until the cell voltage is higher than 2.75V, then charge in standard mode. If the cell voltage cannot be charged to 2.75V within 30 minutes, the charger shall stop charging.
3.Chargers should be equipped with a complete charge detection device. The charging detection device can be checked by timer, current detection or open circuit voltage detection to detect the charging state. When the charging detection device detects that the cell is fully charged, the charging circuit should be completely cut off to avoid trickling charge. The cell charge should be carried out at the temperature of 0°C ~ +45°C. When the cell temperature exceeds this range, it should be placed until the cell temperature reaches the above range.

Evlithium is a leading Lithium Battery & LiFePO4 Battery manufacturer and supplier from China, we have over 10 years experience on providing LiFePO4 battery, Winston Battery, CALB Battery, Sinopoly Battery and chargers, battery management system and other parts for electric vehicles and energy storage system.
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 solar charge 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 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 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.
