I see what you’re saying but in the specific case of getting batteries from Xuba or Dongguan shipped to the EU right now it actually does.
If you want it shipped by air it’s on you to pay those taxes/customs on top of the shipping cost. That’s just their way/shippers way of doing it. Via rail/sea it’s included (DDP) at least to EU countries (they or their shipping company pays for it). Other companies may do it differently. Was told this by Amy last week.
I believe we're on the same page.
I ordered batteries in Feb. via railway transportation. Port of entry in Europe was Poland. The shipper was UPS. All customs declaration were prepared at Shenzen shipping hub and became due at the receiving transportation hub in Poland. The only variable costs, tax and VAT are fixed, is transportation and handling fees.
Now in times of Corona there are not much options to choose.
The Chinese trading companies have their on preferences on shipping companies to deal with.
I'll bring early next week my next order on the way, air freight us far too expensive, railway would be the best option.

? how long did it take you to receive your batteries from the order date?

Thank you. That's quicker than I thought!

Geez Louise !
I bought mine from XUBA, paid by TT, Air Freight to Canada DPP, in other words all taxes, duties etc included. That was pre-covid global lockdown. When you LOOK at the Shipping Cost you also have to know IF you are looking at DPP (with all that added into the S&H cost) or not. If one vendor is $1000 to ship X amount of cells and another is $500 to ship the same, they likely do not include the extra costs for duties, taxes etc. So Apples to Potatoes ! You have to pay attention to that "detail" and understand what it is you are comparing.

@SolarKimmy were these packaged 2 or 4 to a box? I’m glad to see you received them in good condition!

Yes, 6mm

My cells are have reached Europe, Poland, apparently.
I'm having 2nd thoughts about one issue... the first set had some minor voltage differences, so Rain presented me with a 2nd set of cells, closer in voltage. But the voltage of the 2nd set is higher. The first cells were around 3.29V and the second are near 3.33V. What do you think about this? Maybe the same cells and they charged them??? Internal resistance is not very different, 1st to 2nd.
I'm worried now that the cells stay too long at a high SOC... should have noticed this before...

This is not something you need to worry about. 3.33 isn't even full and real damage comes from overcharging, which they are not, being disconnected while in transit!

I also would not worry. I would put them in parallel for a couple of days and they should all get to the same voltage. That is pretty close to normal resting voltage so you could assemble them after paralleling them. Some people like to bulk charge them while in parallel to their preferred number but I think that is optional.
I thought I was missing the screws also but they were put in between two layers of foam on one side of the box in between the two cardboard boxes. You might want to check yours also.

making mistakes so you don't have to...
It took me 2 hours to wire the S16, but I was kinda cheeting there..
I used @ghostwriter66 tip to first use UTP cable to wire the cells, and then connect the BMS spaghetti to those.
Once that part was finished, it took me 2 hours to properly connect (solder) the 17 wires (16 positive, one negative) and protect with schrinkwrap.
Nice Job!!
It looks like the same 250A I have
Maybe smaller, the 150 or 200A?
For both, if you want to blast +150A with those busbars....
You are in trouble.
They appear way to thin to handle anything above 50A without getting HOT.
Nice battery pack!
And good to see you keep the "China margin", better buy 150 or 200A when you need 100A
I hope it will last you many, many years.
Daly is indeed known as "the workhorse", no nonsense "plug and play" BMS.
Personally, I like to see /monitor what's going on under the hood.
That's why I'm about to order also the smart 250A, to use together with the"not smart" BMS.
For me it's worth the extra money to know.

Whow..
1200 amps?
Quick calculate make that you have 12 X battery packs?
Used in parallel, yes?
About 43kwh...
Lol
I thought my 35kwh was huge...
There is always someone bigger

Can you use this BMS for a 2s4p setup? Or would it be better to use 2? @SolarKimmy can you provide a link?
Thanks!
Thanks!
This is not really ideal for LiFePO4 since it has such a flat curve. You really want to top balance before assembling your pack...
Charging a LiFePO4 cell should be done in two stages: a constant current stage followed by a constant voltage stage. When you're at 3.2V, you can essentially go constant voltage.
The way I do it: either each cell is individually charged with a CC/CV capable power supply to 3.5V to 3.65V depending on your preferred state of charge, 3.65 being 100%, 3.5 is 95%. You do this by putting on a 3.5V constant voltage, and wait until the current drops to 0.
Alternatively, you can do this by putting your cells in parallel and doing a bunch of cells at once. The reason I don't do this is to have a full log and id of each individual cell, but this is probably overkill.
I can give more details later, but have to run out for the rest of the day here...

If the curve is flat why does it make a difference? Voltage is voltage. What is the advantage of equalizing the voltage at the top, versus the middle or bottom?

Are these 12 volt packs or did I miss something?
Can you please share who the retailer is?
If you don’t want to just say so but there is no chance of getting banned from the forum for sharing that info.
