Good cells ESIR is so low internally you need expensive gear to get accuracy, 4mOhms can in some cases be a very high result lead to rejected cells.ĭon't forget you really have no access to the **internal** materials, lots of external ones getting in between, different for different cells and measurement tools.Īnd the exact temperature standardization perhaps the biggest variable, how are you solving for that in your quest for "absolute objective" measurement.īeing on a low budget is not conducive to achieving what you are fantasizing about.Īnd it's overkill anyway, not at all required to achieve very useful results in your actual practical goals.Īnd benefit from their experience. How can something be called objective if it varies **a lot** with even slight variations in temperature, or SoC? which is not well represented by voltage. “In theory, there is no difference between theory and practice. It helped me to visualize the process better. My earlier established groups were filling up quickly and I soon found the need to re-sort those groups into finer divisions and I can envision even finer divisions to come. But mainly I have realized why you stated that my sights were too low. I have realized the need for more charging/grading capacity so I decided to buy another MiBOXER 8 bay charger and I'll continue to set an upper charging current limit. I'm seeing as the groups get more populated.Īs I continue to process more batteries, I have, for one thing, stopped calling them "Jewels". Some "groups" have only one cell because they are outliers or just don't have any cousins yet. It was only a week ago that I cracked my first laptop battery and found these beautiful jewels inside and today I have over 50 jewels laid out on my table in groups. I have found these axioms to serve me well. and don't count my chickens before they are hatched. My sights are going higher by the minute, but I was taught to learn to walk before I can run.
