My 8 x 3.2v 280 Ah LiFePO4s order finally arrived at my Northern California carport door May 27, 2020 . My credit card payment went through April 2, 2020, and Xuba transferred this order to their choice of Sea Freight shipping April 13; so that was 45 days on a sea freight ride to FedEx to my door shipping route. I took the risk of ordering during the Coronavirus because I wanted the batteries, the price was good, plus I finally got enough questions answered to trust Amy and Xuba's reputation on this forum. Total cost w DDP shipping (for clarity on shipper handling USA customs and customs duties), to FedEx (I requested UPS or FedEx shipping for the security of their tracking info. once batteries cleared customs and got into FedEx system) was $1022 total; which I think includes minor Alibaba fees, and bank conversion of currency fees. I thought the DDP aspect that may not be available outside the USA, was worth allot (from stories I heard/ to me).
Here's My Curious Creator Take: Glad they finally arrived. Packing was excellent with several layers of cardboard plus foam wrap. Brand new batteries with their little square (certification or warranty?) stickers in tack. Came with 8 bus bars and had one extra screw. Each and every cell is nicely matched in voltage; all measuring 3.35 volts. Picture attached above. I was kind of expecting larger batteries, but a double check on of spec sheet dimensions reveals an exact match. One area that could be improved: I notice the shortish screws for the bus bars bottom out before the kind of smallish bus bars are fully tightened down. I think I will be ok with by adding a washer or two. IMO: That part of battery deal is one that could be improved by manufacturer.
I ordered a couple of options for testing battery capacity on Alibabaexpress right before ordering my batteries on Alibaba (and was confused for short while the two have different log on entries; Alibaba vs Alibabexpress), and those express orders also recently arrived just a few days ago. I will post my capacity results later when I see em. HEY WILL: Thanks for turning me on to how much better LiFePO4s are as compared to Lead Acid, plus also for those informative Youtube lessons I can review when I want a refresher course. :+) I am on a Learning More All The Time ...Roll ... I figure I be learning allot more now from hands on ...
