Note :please carefully check the version you need before you place order !!!

It is with built-in bluetooth and support for Android and Iphone APP to monitor

please contact us for newest app and other documents before you use !!!

Note: The cable is connected from the first black wire on the far right to the total negative electrode of the battery pack, which

is the negative electrode of the first cell of batteries.

Then start from the black wire and start from the first white wire from right to left to the first cell, second cell, third cell

of the battery and so on, and connect to the positive electrode of each cell in sequence. The minimum number of cells to be

connected is 8S, and the batteries of less than 32S are not left empty. After connecting, use a multi-meter to measure the voltage

on the plug row. There is no problem to confirm that the voltage is correct before plugging into the protection board The same

wire is connected to a red wire, regardless of its color), note that the last red wire on the third and last socket is B + which

supplies power to the protection board. It is connected to the cable of the last cell of batteries. That is to say, two wires need

to be connected to the bms on the last positive pole of the battery. There is a hole behind the last red wire of the third socket

and B + is redundant. You can leave it alone. Other instructions are the same as the 24S protection board
