Hi Buddy,
are these cells brand new - never used?
if so, they are already at 50% soc - they come from the factory like that
after the capacity test and sort process
just store them as is - they don't discharge (I have cells that have been in
storage for 3 years that are all still exactly 3.30v)

Subject: [EVDL] Storing / charging LiFePO4
What is a low cost way to keep/store batteries. I have 18 LiFePO4 cell left
over from my switch from lead setting in a box. I got extras for backup and
need to store them until I might need them. I know they should be a stored
at ½ charge but is there anything else I need to do. I also would like
recommendation on a low cost way to charge them for their respite. I would
prefer something out of the box that I can purchase. I would be willing to
charge them in parallel, individual or groups. And last but not least can
someone tell me how I know that they are at ½ charge for storage. The specs
are 40ah with 3.6 volt max, 2.5 volt min and nominal of 3.2.
Thanks in advance,
Buddy Mills
