Basic Functions Over-charging protection Over-discharging protection Over-current protection Temperature protection Disconnect protection Short Circuit Protection Balance Function Short Circuit protection recover Package Contains BMS*1pcs Sampling cable*1pcs Temperature probe(NTC)*1pcs Bluetooth module *1pcs English manual *1pcs Communication function UART/RS485/CAN Balance cable connection Preparation Find the total positive and total negative of the battery pack. Find B-/P- of BMS Insert temperature probe (NTC) into the BMS Welding Note: When soldering, the balance cable cannot be inserted into the BMS (1)Weld Sampling cables: Start from thin black wire to B- (total negative),then connect each cell's positive in order. Last red wire to B+ (total positive) *Note: Do NOT plug into BMS during welding. Insulate unused wires. (2)Check voltages: Use multimeter or wire tester to confirm each cell'svoltage is normal. Fix any miswiring or poor soldering. (3) Weld output wires: Secure B- and P- to BMS with 10N·m torque; weld B-to battery negative. *Note: Insulate P- before final connection. (4) Plug NTC and Sampling cable: Insert NTC, then plug sampling cable toauto-activate BMS. Voltage measurement measure whether the battery voltage（B+→B-)is consistent with the output voltage of the BMS(B+→P-). If the two voltage values are equal, it means that the BMS is working normally. Passive Balance Balanced Start Voltage: 3.4V Balance off voltage 3.6V Balanced Opening Voltage Difference: ≥20mV Balance Current: 100±30mV Balanced start when both of the following conditions are met: 1.The maximum voltage difference between individual cells is ≥ the equalization opening voltage difference 2.The voltage of each individual cell＞The balance turn-on voltage 3.The voltage of each individual cell＜The balance off voltage Note：When the battery is at low voltage and discharged, the maximum balance current is 0.8±0.2A How to wake up BMS If any of the following conditions are met, the system exits the sleep mode and enters the normal running mode: 1.Plug in charger/load. 2.Press the button and release the button 3.With 485, CAN communication activation. Note: After the single or overall over-discharge protection, it enters sleep mode, wakes up periodically every 4 hours, and starts charging and discharging MOS. If it can be charged, it will exit the resting state and enter normal charging APP Download Scan and download the Bluetooth APP BMS activation Method ① Press the activation button on the Bluetooth module Method ② Charge activation APP connection 1、When connecting to the APP, you need to turn on the positioning and Bluetooth of the mobile phone 2、Open the "SMARTBMS" APP, you can see the bluetooth serial number on the home page (this serial number is the same as on the bluetooth module), click and enter to view the battery data. 3、Enter the battery capacity accurately, click "Setting", enter the password 123456, refresh and the setting is successful 4、The SOC adopts the ampere-hour integration algorithm. When the battery capacity is set correctly, after a complete charging and discharging process, the SOC is automatically calibrated Warning 1、BMS is a professional accessory. Misuse will cause damage. Please operate according to the instruction manual or tutorial video. 2、BMS cannot be used in series or parallel 3、BMS does not support the use of reduced string numbers 4、BMS to work for a long time in an overloaded state is strictly forbidden 5、Lithium batteries need a dedicated lithium battery charger, other chargers cannot be mixed to avoid BMS damage and other safety hazards 6、BMS disassembled by the user，No warranty policy 7、BMS is damaged due to unauthorized modification of parameters,No warranty policy Company introduction Dongguan HEYO Electronic Technology Co,Ltd located in Dongguan City,the world factory,a high-tech company engaged in BMS research and development, production and sales.
