Note: Our brand power supply has some stock in the BR/PL/US/RU warehouse. lf you cannot see the option to ship from the overseas warehouse, you can follow the steps in the picture to select the option to ship from the overseas warehouse, (We will automatically equip the corresponding power cord according to your country,Please don't worry）

Note:

4-8S, 8-20S, 8-24S BMS wiring error in string number printing, unified printing of B1+, B2+during production B17+, please refer to the labels on the outer packaging box and product! ! !

Feature

Connection

Connect the APP

1.Download app and manual

2.Hardware connection

3.Startup

4.Open the app and connect the device

5.Set the number of strings and battery type

6.Check the battery status

②.Scan the following QR codes to download app, instructions and videos.

③.Connect the protection board and battery pack according to the following wiring diagram,Make sure that the last power cord is also connected to the main positive pole,The total voltage of the battery pack must be greater than 20V before starting up.

④.Use the display activation button or additional switch to activate the BMS.

⑤.Make sure your mobile Bluetooth is turned on, then turn on APP,click on the top left corner of APP to search for devices,and click on the device name to connect to the default password: 1234

⑥.Parameters need to be set for the first start-up Setting requires a password,The default parameter is set to password 123456,Simply set the number of units and battery type.

⑦.Once the parameters are set, go back to the real-time status page.check the battery status, no error message is prompted and normal operation,blue is the highest voltage, red is the lowest voltage.

⑧.Fault analysis and troubleshooting

1.Ensure that the last "B +" line of the cable has been connected to the positive pole of the battery.

2.Start up after charging and ensure that the charger voltage is greater than 4V of the battery pack voltage.

3.Check whether the charger has voltage out put.

lnaccurate voltage

Measure the actual total pressure of the battery pack with a multimeter and fill the actual total pressure in the "voltage calibration" on the parameter setting page;

Inaccurate current

1.B - and P - of the protection board are two 7awg wires, both of which need to be connected in parallel, otherwise it will lead to current error,

2.Measure the actual current of the battery pack with a clamp meter and fill the actual current into the "current calibration" on the parameter setting page, the larger the actual current, the higher the calibration accuracy.

Inaccurate capacity

1.An initial capacity estimated according to the monomer voltage when the protection board is powered onfor the first time, which is inaccurate

2.After the protection board is discharged to the cut-off voltage and then fully charged ,the capacity is calibratedand the charging process cannot be interrupted;

The designed string number is inconsistent with the actual string number

1.Check whether the "unit quantity" in the parameter setting is set correctly.

2. If there is no voltage in two or more strings in the middle, check whether the acquisition cable falls off

Relay BMS

Current depend on the relay you choose, you can choose relay by your market . MAX is 1000A. our package is 200A .
