Product: 16S 250A Smart BMS For 58.4V LifePO4 Battery Pack On EV With Bluetooth APP Control and Monitor
(3.2V rated LiFePO4 battery pack only)
Feature
◆ UART : It is Daly normal product. UART is Universal Asynchronous Receiver/Transmitter, It transforms the data to be transmitted between serial communication and parallel communication. As a chip to convert parallel input signals into serial output signals, UART is usually integrated into other communication interfaces.
◆ RS485: Please choose the model RS485 of Daly. RS-485 adopts balanced transmission and differential reception, so it has the ability to suppress common mode interference.
◆ Bluetooth module : if you need this function, Please choose bluetooth module, if you do not buy it, we will not send it to you.
◆ Below accessary need you to buy separately.

How to choose the suitable BMS?
You need to make sure of following information
1. Battery type:LifePO4,LTO, Li-NCM battery.
2. Battery pack configuration: No. of series and paralles
3. Constant dischage current: the constant discharge current of your application
4. Constant charge current: the constant charge current of your application
5. Peak discharge current:the highest discharge can a BMS stand
6. Limitation of the controller

BMS wiring directions
First, Preparation before installation.
Make sure the batteries are of good consistency.The volt difference is no more than 0.05V,inner resistance is no more than 5mΩ,capacity difference lower than 30mAh. Connect the batteries in parallel first and then in series.the better performance of batteries consistency is, the higher performance of the BMS.
Second, wiring instructions.
Attention: please use our wires for our BMS.Don’t use other factories’ wires which can’t match with our BMS.
Step 1 B-(blue thick wire): Connect to battery pack total negative pole -
Step 2, Disconnect the wires for batteries from the BMS side.
Step 3,Connect the wires to batteries. Start from the thick black wire to total negative pole(B1-),then connect the 2nd red thin wire to the 1st battery positive pole(B1+)
B2+,B3+B4+......till the last red thick wire.
Step 4,Finishing all the wires to each batteries,don’t plug into the BMS directly. We suggest you use multimeter measure the voltage of two adjacent metal terminals(You can see the white connector with silver metal pins on the BMS).if the voltage is 3.0~4.2V(LiNCM),2.0~3.6V(LiFepo4), 1.5~2.75V(LTO),which means the wiring is correct.
Step 5,Ensure the wires are connected to batteries correctly, all voltage is normal, you can plug the wires into the BMS.
Step 6 P-: Connect P-(black thick wire) to load - and charger -
(if you ordered “common port”)
Charger+ connect to C-(yellow wire) load+ connect to P-(Black thick wire)
(if you ordered “separate port”)
Step 7 charger+ and load+ connect to battery +,please use thick wire
Third, Measure the total volt of the pack, and the output voltage of the BMS.if the voltage is the same,it means the wiring is correct.You can use the BMS now. Otherwise please check the wiring again according to the tips above.
