Why Choose JK BMS
1.Active balance functionality, no need to lose the battery capacity to balance the voltage difference of cells, raise the battery usage efficiency for 95%
2.It has the protections of Over-charge/Over-discharge/Over-current and Short circuit Over-temperature protection etc...
3.Single battery series voltage range is 1~5V, the precision is 5mV
4.With the function of coulomb meter, the remaining power is very clear
5.BT communication function, the battery status can be displayed on APP

FAQ
The App is Chinese,I need English version
the language can be changed in the setting.
The BMS does not turn on,no light
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.
The voltage is not correct
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.)
The current is not correct
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.
The capacity is not correct
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;
The series number is not correct
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
