Assembling your own DIY battery pack using existing lithium cells, such as 18650 cells, is an exciting and rewarding project. With the right materials, tools, and safety precautions, you'll be well on your way to creating a custom battery solution tailored to your specific needs.
If the voltage is correct, charge the pack using a battery charger/tester specifically designed for lithium-ion batteries. Monitor the charging process to ensure the pack is charging properly and safely. Assembling your own DIY battery pack using existing lithium cells, such as 18650 cells, is an exciting and rewarding project.
To build the battery pack, we are taking 4 cells in series and adding a parallel cell, so we have double the voltage and capacity per cell. See the diagram above for how to go about connecting the cells. The only limiting factor is that all of the cells need to be identical.
Let ’s take a DIY 4S battery as an example (4S 5000mAh 35C) I.Required materials The difference in the internal resistance of cells determines the battery capacity and life. The key point of the performance of self-assembled battery pack is that the internal resistance of multiple cells should be similar.
Materials needed: 2x 18650 or 21700 cells (they must both be exactly the same cell!) Let’s first list the tools that I used: Making a battery pack is dangerous. Ensure that you have a basic understanding electricity and lipo & li-ion battery tech. This guide might not be perfect, so proceed at your own risk.
For a secure and long-lasting connection, use a spot welder. If a spot welder is not available, soldering can be an alternative, but be cautious, as excessive heat can damage the cells. Attach the Battery Management System (BMS): Connect the BMS to the battery pack according to the manufacturer's instructions.
