1 How to connect Bluetooth
Apple connection: After the protection board is turned on (within three minutes), you can directly connect to the software. You can't connect to Bluetooth when it is in standby. The protection board can be regarded as non-standby during the charging and discharging process. You can connect Bluetooth (non-working state) After three minutes, it will stand by and cannot connect to Bluetooth).
Android connection: After the protection board is turned on (within three minutes), the mobile phone Bluetooth opens the search for pairing, the pairing password is 1234, and after the pairing, search the connection in the software. During the charging and discharging process, the protection board can be regarded as non-standby state and can be connected to Bluetooth, (non After working for three minutes, it will stand by and cannot connect to Bluetooth)
2. How to set the communication password so that it cannot modify the parameters
When the software is opened, you can see a verification password and a modified password,
The protection board has no password when it leaves the factory,
You can modify the parameters by connecting to Bluetooth,
Enter 8 digits in the box after changing the password, for example 12345678, and then click Change Password,
No parameters have been clicked within three minutes,
After three minutes the password is set to 12345678, or the Bluetooth connection is disconnected
, The parameters cannot be modified next time you connect to Bluetooth,
The parameters will be automatically restored after modification,
At this time, you need to enter the password 12345678 in the frame behind the verification password and then click the four characters of the verification password to modify the parameters.
3： How to set the parameters?
The factory default of the protection board is the ternary cell parameters,
If the 24S protection board purchased is a ternary 24 string parameter,
The 16S protection board purchased from the factory is ternary 16 string parameters,
Purchase 20S protection board leaves the factory is ternary 20 string parameters
The 32S protection board purchased from the factory is a ternary 32 string parameter,
First of all, determine what your battery is
(Common batteries are ternary lithium, lithium iron phosphate, and lithium titanate)
If we use ternary lithium and connect to Bluetooth, we need to find the number of battery strings in the parameter settings
Modify it to the actual string number of your battery
There is also a physical capacity to change it to the total capacity of your battery as much as the ampere hour
No need to modify other default
If it is a lithium iron phosphate battery. Please click on the lithium iron phosphate parameter system will automatically change to lithium iron parameters, and then set the string number and physical capacity, if it is a lithium titanate battery, please click on the lithium titanate parameter system will automatically change to titanium Lithium acid parameters, and then set the number of strings and physical capacity, it is very simple as long as you will use a smartphone to follow this instruction to operate basically no harm.
4 ： FAQ: How to calibrate the total pressure is not correct?
Connect the mobile phone APP, open the parameter settings, there is a "total pressure calibration parameters" or "total pressure conversion AD parameters", this value can be adjusted up or down, note that it is not adjusted to the current total pressure, slowly increase or decrease, The total voltage will also become larger and smaller accordingly, just adjust to the current total voltage equal to the actual total voltage.
FAQ: How to calibrate the current is not allowed?
Connect APP, open the parameter setting, there is a current sensor range, slowly increase or decrease this value, the current will increase or decrease accordingly, until the displayed current is equal to the standard actual current
