How to connect 3S BMS with 12 Volt Battery
Overview: how to create a 12V lithium battery pack using 3.7V 18650 lithium-ion cells and a 3S BMS board. The BMS ensures proper charging, balancing, and protection for the battery. The video covers essential steps, including connecting the cells in series, soldering wires to the BMS, and testing the battery voltage and current.
Detailed Steps The video provides a step-by-step guide:
1 Cell Connection: The presenter connects the 3.7V cells in series to achieve a 12V battery. The BMS ensures that each cell is balanced during charging and discharging.
2 Wiring and Soldering: Wires are soldered to the BMS terminals (B+, B-, BM, P+, P-) as per the BMS datasheet. Proper insulation and secure connections are emphasized.
3 Testing: The battery voltage and current are measured using a multimeter. The BMS protects against overcharging, over-discharging, and cell imbalances.
4 Final Tips:
The video concludes with additional tips and diagrams for creating different types of BMS batteries.
In this instructable, I will demonstrate how to connect the cells to the BMS using cell holders for easy testing. I will also show you how to charge the lithium-ion cells using a DC-to-DC buck boost converter module to provide a constant voltage and current.
Things you'll need:
3S BMS
18650 lithium ion cells
lithium ion cell holder
Solder the 3s BMS with the lithium ion cell holders as shown. Make sure to connect the cells properly.
Calibrate your power source to provide a constant voltage as per your BMS requirement and constant current as per cell requirement. Make sure to read the datasheet of the lithium ion cell you are using to make sure the maximum current that you can provide during its charging cycle.
Finally, test your circuit by first charging the lithium ion cells and then discharging them using an electronic load. It is very important that the BMS or the cells do not heat up during this process. I've made a complete video tutorial on this project so go check it out.
