Hi Gary,
I have some new measurements with the new 20 magnet rotor (see attachment) which I hope you want to have a look at with me:
Cycles 1/2/5/6 are all done with the same input/output batteries as you can see, and done as previous: charge up to 15.3V, discharge 1Ah. Like with the previous rotor, the results are very inconsistent… after cycle 1 I had high hopes, but then with the results of cycle 2/5/6 that hope was through the window completely
So then decided the replace the output battery B (AGM/12AH) with one of me new bought batteries, LA1 (flooded/24Ah), to see if then the outcome would get more consistent. As you mentioned before, Batter B (and A) may be damaged because of being discharge at high amperes early in this SG development.
Before I started cycle 7 with LA1 at the output, I did 2 discharge/charge cycle of 2Ah, and charged it with a regular charger (Noco G3500) at the 0.9A setting. Then I discharged 1Ah out of it and started cycle 7. As you can see in the remarks, I quit the test after 62 minutes since the voltage was not raising above 14.75V and the battery was producing a bad smell, probably because it was producing gas instead of charging. I drained 1Ah out of it again and then started cycle 8 with the same result but now at 14.86V. I assume that initial charge/discharge cycles I did with the regular charger were not enough to get the battery up to it’s full performance yet. So my question would be: what is the quickest way to get it there?
When it says that no more of 20% should be discharged out of it, than I could do discharge cycles where I discharge 0.2*24Ah = 4.8Ah out of it (instead of 2Ah or 1Ah). But to stay on the safe side I could go for e.g. 4Ah. And then recharge with the normal charger.
Or do you recon that for this “break in” process, it doesn’t matter whether I discharge 1Ah, 2Ah or 4Ah out of it, that it is more a matter of the amount of cycles, and not so much the depth of discharge. I also have a 3.5A charging setting which I could use*.
Is there any indicator telling me the battery is ready to be charged up to 15.3V? (Other than trying to charge it with my SG up to that level).
Many thanks in advance,
Regards
Rodolphe
