I think your LifePo4 graph is wrong and mixed it up with Li Ion. No graph on the net is this high of voltage as you show the curve to 4.2 volts and low to 2.5. Most LifePo4 shows 14 % which is right at the lower knee at ruffly 3.18 volts. Your graph shows almost 3.38 at 14% and this is definitely wrong.
Great overview! While I am a EE, I appreciate the research you did so you could cover the many non-obvious side effects of power system grounding.
I have a suggestion: There are many examples on the Internet of fusing (usually circuit breakers) both the positive and negative connections for a device. In particular, I see many examples of this on the wires between the solar panel(s) and the solar charge controller.
From your discussion of grounding, this would seem to be counter productive, as well as unnecessary.
Some clarification on this issue would be of value to many of us.
We would call it a fraud considering that amy must be a professional lyer considering what she is promisierung compared to what she has delivered. EVE sells the LF280 cell with test reports from the factory floor for free and their spec sheet tells you exactly how to measure the battery right and what to get: 280 Ah with a 1C testing which would equal 280A current and a discharge time of 1 hour.
you had piad 4$ extra for the testing where they discharged that roughly 10 times slower and then the 280 Ah is no longer valid cause it must be a lot higher if you discharge with lower A or C rate. But you just got 280,5 Ah guess and most likely at 25°C ambient temperature which means less resistance and therefore a lot more Ah. But you just got 280,5 Ah which would equal maybe 272 Ah with a full 1c rating test.
these are quite old most likely used cells and for sure not grade a cells at least if you compare them to the EVE reference document where they do explain how to determine if you got a good or bad cell.
