[RE-wrenches] Huge battery bank recommendation

As a side note, if you use the 2YS31 Surrettes, as I did for a single 48V string about a year ago.  You may want to have them shipped from Canada as a batch.  I'm almost certain that my pack of 24 2v cells was a mixture of manufacture dates, 3 of which were in the "distribution chain" for too long.  So I have 3 cells that, despite the hours and hours and days of charging I cannot get above SG 1.252.  The rest of the cells are in the 1.268~1.275 range after EQ.  Yes, I've talked to Steve Higgins about this a couple times....so far, I don't have the answer I would like after having spent a very large chunk on $$ on what I'm hoping is a 15 year pack.

  Good point Jason.  To clarify this is a 48V system.


  Thanks

    Not that I have an answer for you, but I'm curious, too. You need to specify voltage to get a good answer.

      Hi wrenches,


      I am consulting on a job that requires an 8000 Ahr battery bank.  This is quite a bit beyond my normal battery bank realm.  What would you recommend for this?


      Thanks in advance
