JK BMS 1A 2A Active Balance Lifepo4 BMS 8S 16S 24S 100A 150A 200A 500A Smart Board with Bluetooth

the language can be changed in the setting.

1、Ensure that the last "B+" line of the cable has been connected to the total positive terminal of the battery.
2, charging activation boot, ensure that the charger voltage is greater than the battery pack voltage of 4V or more
before activation.
3, check whether the charger has voltage output.

1、Measure the actual total voltage of the battery with a multimeter, and fill in the actual total voltage into the parameter setting page "Voltage Calibration".(voltage calibration" is on the setting page.)

1, the B- and P- are two 7AWG wires, both need to be connected in parallel
Otherwise, it will lead to current errors.
2、Measure the actual current of the battery pack with a clamp meter, and fill in the actual current into the parameter setting page "current calibration".
egg page "current calibration" inside; the larger the actual current, the higher the calibration accuracy.

1. An initial capacity is estimated according to the cell voltage when the BMS is powered on for the first time,and this capacity is not accurate;
2. But after the battery is discharged to 2.5V and then fully charged to 3.65V, it is calibrated.
This top-balance process cannot be interrupted;

Check the "Number of Units" in the settings
1. Whether the number is correct;
2.If there is no voltage in the middle of a series of 2 or more, check whether the collection line is disconnected
