I ordered mine on April 5, and it was shipped April 13 via sea DDP. The FedEx tracking went live on May 22 and they are scheduled to be delivered to me in Michigan tomorrow (May 29).
XUBA:: How long is it taking you guys to get your XUBA shipments??

Ours must have been on the same boat. Mine were shipped on 4/13 and are being delivered by FedEx on 5/29 in Michigan too.

small world hi neighbor
No, we found the answer. The shipping company messed it up and shipped by rail even though we asked for sea. The tracking UPS number gets created ahead of time and only starts moving once it gets scanned by UPS.
It seems to have already cleared through EU customs (Poland) and (according to the shipping company) picked up by UPS this week but still not scanned yet. Looks like UPS is sitting on a bit of a backlog. I hope for the best since I have to go away in about a week and want the batteries before that.
Because they're over 40kg total
If you think about it, even with shipping, $1000 for 12V 560Ah of capacity is an excellent deal. If you bought Battle Born, you would only get 100Ah.

If you are in the States, you are paying for someone to move 44 lbs to the opposite side of the planet. Think about how much it would cost to go pick them up.
I went with Shenzen UNIS for mine and it was $140 by sea. The downside is that a month later, I'm still waiting for them.

Got mine last Friday 5/29/2020 they were ordered on from Xuba on 4/5/2020 shipped via sea to Michigan.
They were in perfect shape and all measured within a thousandths of a volt of each other. I purchased 17 of them and am in the process of checking the capacity now. Very happy.

For those of you that have already received your batteries how do you like them so far? Have you done any capacity tests yet; are they matched pretty well for top and bottom balancing; does anything on them or thier paper work say that the 280ah cells are grade A? I've noticed on their web site that only the 105ah cells are explicitly called out as grade A . What do you all think about this?
Hey newbostonconst, what size did you order, 280ah or 105ah? Glad to here they looked good and tested close for voltage. Looking forward to hearing your experience with capacity tests. If you have the 280ah cells is there anything on them or with the paper work that specifies them as grade A?
Thanks,

I doesn't matter to me as long as they have the capacity and are reasonably close in internal resistance. At less than $125 per kWh they are a good value. I am going to treat them conservatively.

My 8 arrived yesterday and were in perfect shape. Assembled and balanced them yesterday and it didn't take too long to balance and charge to 3.4v ea. Been running a capacity test since last night @19a and am 4156wh into it. Currently sitting at 3.26v ea. Unless I start a fire soon I'm completely satisfied so far.
Just need my bms to arrive.

I'm very happy with my 8-280ah LiFePo4 batteries. I top balanced them at 3.6 volts and I'm within 10 mV. I have not discharged them all the way yet but so far at 25% discharge, I'm still within 10 mV. The internal resistance on all of my cells was 0.13-0.14 ohms. I finished building up my pack today and still testing with my inverter and solar charge controller. Setting my Absorption voltage at 28.4V (3.55V cell) and Float at 27.0V (3.375V cell) on both inverter/charger and SCC. Inverter low voltage warning at 24V (3.0V cell), cutoff at 23V (2.875 V cell) and I have set my Chargery BMS at a High Voltage cutoff of 29.2V (3.65V cell) and Low Voltage cutoff at 2.8 V per cell. I made my own busbars from 0.1875" x 1" copper bar stock. Building a movable (although heavy) setup using a Harbor Freight 18" x 30" wood dolly as the base and 3/4" plywood for my box. Approximate weight of the entire system estimated at 200 lbs. Amy told me when I was ordering the batteries that they were brand new Grade A cells, and I believe her. The terminals were spotless.

That's interesting.
What's the purpose of the portable system?
I'm planning to install it to run some essential home loads with off-grid solar, but I wanted to put it on wheels so I could move it around for increased flexibility if necessary in an emergency. Due to its weight, it probably won't be moved all that often, but its on wheels just in case.

280 I questioned if they were grade A and they said yes....haha...highly technical method.
Mine went live too! Scheduled for 6/12 delivery. Order was placed 4/23.
