I purchased min DDP (delivered duty paid) so the seller took care of any duties and I did not see any paperwork that even gave me a clue.
I got the first 32 Lishen 280Ah cells from one different vendor but this second vendor said they are due to arrive at the long beach California pot on 12/21/2020. so probably after Xmas before I get them. today I am hooking up an inverter to the 1st battery bank of 16. wired 2P8S for 24 volts. I will make a second bank of 16 soon. then when the other 32 cells arrive I may try the 48-volt battery bank. the 24-volt battery bank is 560Ah.
long beach California port- typo; expect to be slow through the ports - that is what the vendor says also.
Hi there. Did you receive your cells from Shenzhen shouhuzhe? I ordered thru alibaba on the 4th of December. Today I got an email saying they had been delivered and the funds released to the seller. I contacted Paula li and was told they will still be on the train. No explanation of why the shipping is marked as express when it’s not. They say not to worry. Just can’t help feel a little on edge about it
Not yet & feeling a bit edgy myself.
ending
I have no new update yet but that the ship was in port at long beach California on December 22nd. maybe in a few more days.
As for meI have no new update yet but that the ship was in port at long beach California on December 22nd. maybe in a few more days.
I ordered these on the 18th of November. much patience is needed!!!!
No one can give you a recommendation because no one knows how many amps you will be drawing from your battery. What size inverter are you planning on? What are your loads?
I'm thinking I can use a 3000 watt inverter. I'm using it for a RV and the biggest load would be the AC unit. I have run the AC off a 2000 watt Honda inverter generator before so I think a 3000 watt inverter should be fine? Although the AC manual calls for a 3500 w min generator. https://www.dometic.com/en-us/us/pr...700.12243863.0.0.3b3c3e5fia50fE#documentation

I am in the same situation as you. It is my intent to run 24V from the panels to the 8 cells. Don't know if you are going 24V vs 12V? I have been talking to Steve about his Overkill BMS as you have, but the 100A limit isn't adequate for the 3000W inverter. Maybe there is a way for each 12V bank to have its own BMS but I would prefer to have one that can handle 8 cells in series/parallel. I am wondering if the BMS would get confused being attached to two 12V banks?I'm thinking I can use a 3000 watt inverter. I'm using it for a RV and the biggest load would be the AC unit.

I have also been researching what I would need for the AC. You have a 13500 BTU Dometic, I have a 13500 BTU Coleman. I haven't read the tag on the AC, but somewhere I found it runs at 13.1A under normal conditions and 14.1A when running in desert conditions. Coleman says they don't make generator recommendations, but they do say to multiple the amperage by 2.5 to accommodate startup. So they are saying you might need 35.3A at startup. I hoped that a 3000W inverter would be adequate and praying the fridge doesn't kick on at the same timeI'm thinking I can use a 3000 watt inverter.

It doesn't matter if you put them in series or parallel. If you're driving an inverter, it's going to take the same power from the batteries. So at 24v, it would draw 125A. At 12v, it would draw 250A, or 125A from each of two batteries in parallel. Or am I misreading what you intend?
look at the Electrodacus SBMS0 for a 24-volt solar battery management system. i have mine hooked up to 16 Lishen 272Ah cells. 2P8S battery bank configuration. works great.
