🔋11.1V Battery Pack DIY Guide 💡
🔧 Preparation tools and materials: 10 18650 lithium batteries are the key to building an 11.1V battery pack. These batteries have a diameter of 18mm, a length of 65mm, and a single rated voltage of 3.7V, but can reach 4.2V when fully charged.
💡 Understanding battery characteristics: Series and parallel connection are the foundation for building battery packs. Parallel connection, 3 18650 positive connected to positive and negative connected to negative, combined into 1 group. Then, these groups are connected in series to form a battery pack of approximately 12V.
🔩 Assembly steps: First, connect three 18650 batteries in parallel to obtain the first set. Next, repeat this step to obtain the second and third groups. Finally, connect these three groups in series to form a complete 12v battery pack.
🔋 Testing and Verification: After assembly, it is essential to test the voltage and current of the battery pack to ensure its safety and stable performance.
💡 Tip: During the assembly process, ensure that all connections are secure and safe to avoid short circuits or damage to the battery.
Now, you have successfully assembled a 11.1V battery pack! 🎉 Whether used for electronic devices or DIY projects, this will be a powerful power solution.
