    Selling Fully Off-Grid Set-up (Husband died of Car Accident) Need help!

    My husband and I lives in Northern Arizona. He has been working on this project for about a year now, learning and assembling each part everyday. He looks stressed, but happy of his achievements. We were able to live in a 27" 1997 Prowler (RV Trailer) and even charge my BMW i3 at night due to...

    CATL 271Ah cell issues.

    ^This. Also, why have they pulled some back, yet others are still receiving them? I have a feeling that it wasn't their choice. If the shipper had pulled them back, they would have pulled back all remaining orders. I feel like some leg of UPS probably refused to move them when they felt...

    CATL 271Ah cell issues.

    唛头 pretty much translates to "shipping mark" 未 translates to "not yet", "have not" or used at the end of a sentence to ask if something is done yet.

    CATL 271Ah cell issues.

    Who's we? You work at a rail yard? That's about what I figured though. Some process along the way where when an item comes out it goes into final shipper's hands. It wouldn't make any sense to parse a container at a yard. Probably wouldn't even be allowable for a 3rd party.

    CATL 271Ah cell issues.

    I don't remember being told grade when switching to the CATL cells from Lishen, but I DO have a message from my conversation history with Michael where he specifically stated that they are "new" and not the cells he previously had from EV packs.

    CATL 271Ah cell issues.

    I hadn't noticed this previously, but the Origin Scan in the tracking history shows that they were initially scanned in from La Mirada, CA, which is 24 miles away from Chino, CA, where they are destined to now that they are on their way "back to the shipper". I also verified that there is no...

    CATL 271Ah cell issues.

    I would tend to agree with you, but I live 4 hours from Chino, CA (KingSpeed) and, assuming they are being sent back due to shipper request because of wide spread damage to every order that was sent out, it would be difficult for them to have been damaged on the short couple of hops they would...

    CATL 271Ah cell issues.

    Just got off the phone with KingSpeed. They were unable to provide any sort of information. Not because they wouldn't, but they appeared not to have it. The woman asked for my tracking number, saw the tracking history from the screenshot and sounded surprised. She stated that they are just a...

    BMS Suggestions for 16s3p 280ah CATL

    Yes, you are correct. I will be building 3, 48v/16s packs that I will place in parallel with each other to create one bank. Also, they will not be going into an already existing bank. I will not be trying to enter parallel-series wire cells in any configuration where it would look like 3x...

    BMS Suggestions for 16s3p 280ah CATL

    This is what I've always thought. Logically it's what makes sense. It seems like mismatched parallel strings used together would cause discharging to the lower capacity strings as they discharge quicker. The larger strings would "balance" the smaller strings by charging them as voltage drops...

    BMS Suggestions for 16s3p 280ah CATL

    Long awaited, 50x CATL 280ah will be hitting my door within the next month. I still need to make a BMS order and am hoping to get some good suggestions on the best way to manage these in 16s3p. I have several questions that I'm still unsure of after digging through quite a few threads. I've...
