How To Cycle Test and Match LiFePO4 Cells

In search for the perfect pack! In this video I show you how to cycle test cells as well as batch and match them to build a matched pack. I found that LiFePO4 cells will degrade at a rate of about .5% per year just sitting on a shelf, not in use. Its important to perform a maintenance charge of your cells if you are going to store them for any length of time over 6 months.
I also found when purchasing cells that are unmatched from over-seas distributors that they can have a deviation of 4 amp-hours. This is the difference in capacity between the lowest and highest capacity cell.

Reasons To Capacity Test:
1. To ensure you got what you paid for.
2. To find the deviation (difference between lowest and highest cell) for building matched packs.
3. To check for cell degradation over time.
4. To ensure satisfactory voltage drop/load test.
