Balancing Matched VS. Mismatched Cells - How the BMS Does it and More!

Quite possibly the most comprehensive video on this subject yet! This video is all about balancing matched VS. mismatched cells. It is more about how the BMS works rather than balancing methods; although, you could use this video as a balancing guide. I will cover in detail how the BMS achieves balancing through active or passive balancing. We will also attempt to discover the method (if any) in which the BMS remembers the pack state for subsequent cycles. I also cover charging stages for LiFePO4 cells. During the video, we will cover how to top balance cells using the raw, parallel pack method (no BMS), as well as series pack balancing using a BMS. The BMS balance will be time trial style, and we will see how fast the BMS can balance matched V.S mismatched cells. See my website for more details: https://www.natesdiysolar.com/project... SFK 12V Battery Build #1:    • DIY LiFePO4 12V Battery Build - 301 S...   My Cell Distributor Recommendation * If you mention my channel, it will help me out. Thanks! I have personally purchased 48 cells from this company, and it is one of the larger ones out there.

Confirm that the internal resistance is the same for all cells. Make sure the cells have welded studs. Ask the supplier if the cells are from the same batch. Check the datasheet for the cells to ensure the C rate are suitable for your application. For a 12V battery, you will want at least a 1C rate, continuous discharge.
