In a hurry...skip to spoiler...last paragraph and pictures.
Been lurking in the shadows and dark corners of this forum for months now...I have to say the information and general knowledge, not to mention helpfulness, of you members is priceless. Would never have attempted this project without knowledge gained by reading this forum. With that said...wish me no fires!!! ??
I needed to replace an aging and tired "golf cart" storage bank in my garage and wanted something "safer" to be in human spaces. Been testing solar for several years now while building a conex container cabin for some very remote property I own in the Ozark foothills. Cabin is completely off grid so I want to know what my limitations are while on-grid in civilization. Reliable high capacity energy storage is the last piece of my puzzle.
Ordered 24 EVE 304AH cells from Emily through Alibaba. Paid with CC directly through Alibaba pay and the card I used has no foreign transaction fees. CC company confirmed buyer protection for 180 days from expected product receipt date and automatic refund if not received. Capital One if anyone interested. Payment was made September 27th (no issues with approval by CC or Alibaba) and received notice shipped October 12th...slow boat. I did have to request a tracking number mid October but really did not matter as there never was any updated information on FedEx site when 12 boxes showed up December 29th. Emily was responsive to inquiries and answered questions in timely manner...but I would not say proactive, more reactive. Freaked a little December 27th when Alibaba released funds and closed protection window as no updates for 90 days. Emily talked me off the edge...Capital One held on other line. Holiday and work schedule did not permit full inspection until this evening. Happy New Years Eve! All 24 cells appear to be brand new with no dents, dings, or noticeable bloating. All labeled with voltage and IR at time of shipping and random testing shows voltage spot on with .01 to .02 variances in IR. Cells came with welded studs, although I expected threaded terminals and grub screws. Welds appear satisfactory and I guess is an upgrade other than connection surface area considerably less than it would normally be. At least now I don't have to worry about stripping threads with grub screws. QR codes are stamped into aluminum top plate and are intact. Need to find thread on decoding date code to see when manufactured. More for information records and curiosity as capacity tests are more important.
Nerve racking experience only because of state of shipping now...93 days from payment to receipt. Very happy with condition of cells and packaging. I will be updating as top balance and capacity tests proceed over the next several weeks.
Happy and Safe New Year to all!!!
