Good day all,
Maybe a very stupid question, but my mother taught me:
The only stupid question, is the question that is never asked!
So here it goes:
I am segregating my cells in there different stadia of health that will make it to my powerwall:
Between 80 -90% and between 90 -100%
(freaking IR meter did NOTarrived yet, BAST*** going to open a dispute)
For the mah is clear(special thanks to Daromer!!!!), but do you use everything above 80% in youre packs, or:
You use 80%-90% in one string and 90%-100% in another string.
Or you just mix it up?
What is wisdom.
I am able to make my first 2 strings (48v x 2) from 90-100%
And then 1string(48v x 1) from 80-90% soh cells.
Or just........
Everything above 80%soh is fine and the mah are more important?
So quiastion a would be:
Does it matter that you divide at 10% soh in your powerwall?
So question b would be:
Would it make a significant difference, if I put 80-100% together?
I think, the strings with only 90-100soh%will last longer
and 80-90% soh strings will need maintenance earlier?
My first setup, needs only 600-800 watt an hour 24/7 @230v for the pound(got ~3500 cells ready @~2750mah)
Thanks in advance, best
