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.
