Hi guy's
What is the proper voltage for a 18650 cell for in storage?
I don't think i will have my wall up and running before the end of this year.
I thought it was 3.5 volt, but someone (i really can't remember who, sorry) told in a post that it was 3.7v.
At 3.7 volt he stated: at 3.7 volt the cell chemistry is at his perfect balance.
The storage temperature will be around 18-20 degrees celsius.
The last stage of my testing board is equipped with aadjustable psu.
I have already a ~1000+ tested, ready to use cells stored at 3.5v and ~250 at 3.7v.
When i tested "ready for use" a 2800 cells i will begin to build my packs, and give them a charge to 4v,discharge to 3.1 and charge up to storagevoltige again.
Thanks in advance, best
