The fundamental is very simple: Just to combined the number of LiFePo4 cells in series and parallel to make a bigger pack and finally to ensure safety by adding a BMS to it. The LiFePo4 cells come in a variety of sizes, but here I have used the 32650 type. My Book : DIY Off-Grid Solar Power for Everyone
Assembling the battery pack is a pivotal phase in the construction of a DIY lithium ion battery. This process involves arranging the selected lithium ion cells in a series or parallel configuration to achieve the desired voltage and capacity while ensuring structural integrity and electrical connectivity.
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.
By adhering to these guidelines and exercising diligence and precision, you can effectively solder the lithium ion cells for your DIY battery pack, ensuring robust and reliable electrical connections while upholding the safety and integrity of the battery assembly.
Ultimately you will make a single cell with a higher capacity. Example: Connecting two 3.2V / 6000mAh cells in parallel will produce 3.2V, but the total capacity will be increased to 12000mAh. To make the battery pack, you have to first finalize the nominal voltage and capacity of the pack. Either it will be in terms of Volt, mAh/ Ah, or Wh.
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.
