BMS Protection Board, Over Current Protection Lithium Battery Protection Board with Collection Cable for Electric Bike for Scooter

Feature: 1. High accuracy voltage detection circuit, exquisite workmanship for maximum durability. 2. This protection board has the functions of over discharge protection, over current protection, and over charge protection. 3. The battery charge and discharge can be controlled, and the standby current consumption is low. 4. The batteries are connected in series with 7 groups, please ensure that the voltage of each battery is the same. 5. The wiring mode is the same port, and the protection board works well inelectric bike and scooter. How to Use: 1. First connect the B? line to the battery negative terminal (the B? line must be soldered with a short wire), and then connect the flat cable (before connecting the flat cable, be sure to unplug the flat cable from the board). 2. Start wiring from B?, connect B? to the total negative electrode of the battery, connect the second cable B?1 to the positive electrode of the first battery, and connect the third cable B?2 to the positive electrode of the second battery, and the fourth cable B?3 is connected to the positive electrode of the third series of batteries...and so on. 3. Finally, measure whether the total battery voltage is equal to the output voltage of the protection board, and&nbs
