lifepo4 battery pack installation precautions
lifepo4 battery pack installation precautions, the open circuit voltage must be measured before the lifepo4 battery pack is installed, the open circuit voltage difference should not be greater than 50mV, and the battery test should be done and recorded.
Why should the battery pack be recharged before installing the lifepo4 battery pack?
When the lifepo4 battery pack leaves the factory, the positive and negative plates have been activated by charging and discharging. If the installation date of the lifepo4 battery pack is far from the factory date, the capacity of the lifepo4 battery pack will inevitably be lost after a long-term self-discharge. In addition, the lifepo4 battery pack is generally about 60% charged at the factory, so the initial installation The lithium battery pack should be recharged.
Discharge test before installation of lifepo4 battery pack
The capacity test can be performed on the battery pack at the hour rate of 0.1C10(A) and 0.2C5(A) with a dummy load. This test also does not need to be connected to the battery management system, just connect the battery packs in series, but the discharge process During the test, the voltage of the battery cell must be strictly detected. During the test, the total voltage, discharge current, and cell voltage of the battery should be measured and recorded every hour, and it is calculated whether the actual battery discharge capacity is basically consistent with the rated capacity of the battery. If the battery discharge test is qualified, then recharge the battery.
Troubleshooting abnormal discharge of lifepo4 battery pack
If the discharge capacity of the battery pack is too different from the rated capacity (greater than 15%) when the discharge reaches the termination voltage, it means that there may be a problem with the factory capacity of the lithium battery pack, and you should contact the relevant manufacturer to deal with it in time.
The lifepo4 batteries for the following applications need to be connected in series and parallel
1. The products in the following industries need to expand the voltage and current according to their own working voltage and demand capacity when using lifepo4 battery.
rv(recreational vehicle)/marine/golf cart/scooter/solar storage
Commonly used single battery specifications are as follows:
12V 50AH Batteries,12V 120AH bluetooth Lithium Battery , lifepo4, 12V 100AH Batteries,24V 60AH Lithium Battery, 48V 50Ah Batteries.
Users can connect in series and parallel according to the above specifications to expand the voltage and current.
2. The following products do not need to be connected in series and parallel.
UPS Battery/Power staion
Common specifications are as follows:
10KWH Energy Storage Battery, 5KWH LiFePO4 Powerwall For Home Energy Storage System.

The engineer team of the OEM manufacturer of Keheng lithium battery can provide technical solutions for installation and maintenance free of charge for all users. Welcome to leave a message in reviewl or quara for questions or email consultation.
The above are the precautions for the installation of the lifepo4 battery pack. In addition to the manufacturer must recognize and prevent the possible safety risks caused by the use of lithium batteries, the general consumer also has the responsibility to face the dangers of lithium batteries and understand how to use them safely and reduce lithium Injury caused by accident of battery pack.
