This is expected. There exists no list of what cell corresponds to what manufacturer ID and Product ID. If you notice under your screenshot for product ID it shows unknown. That is why it reads 0 Ah and Wh as the app simply does not know and does not want to provide wrong values. It should be...

I hope to be able to come back and test this in the future. While these were outside cells, we also have a crate of L135F72 cells that havent been touched in years. Hopefully it has the original shipping report in it. I'm also looking at a set of original blue headway cells to test that have...

Not mine, don't even get to keep em. They have already been returned to their owner.

There is endless discussion these days here about the effects of calendar aging on cells. Even more so with cell cycle lifes hitting 15000 cycls or more. Unfortunately there is a lack large scale testing as it is both expensive and time consuming. Well through my job I was given a rare...

They used to back in the day, this is for an original LF280, dated April of 2019. Compression has just become a standard and mandated practice in industry now.

Updates the 46145-18ah datasheet to an official copy from Paragonage Updates the 32140-10ah datasheet to more proper copy from Paragonage Adds a rebranded 18650-1.3ah datasheet

All depends on the true specs of everything. Start by seeing if the 12V panel is actually 12 volts open circuit, many "12v panels" are in the 18-22V volt open circuit range as they are designed to be used with buck converters to charge 12v batteries. 5s is a possible setup for the simple setup...

I went through all the LTO cell datasheets I have. All the different cell manufactures spec the discharging cut off voltage is 1.5V. 3S would give you 4.5V as a low cut off, likely acceptable for your proposed 5v application, if you can ensure it shuts off at 5V. The cells will not shutoff...

I have some some lab data on this. We were paid to evaluate cell replacements for a now discontinued cell. This will be lighter on details than I'd like because of it being private paid testing. At 15F the damage can be as high as 16% SoH after 10 Charge and discharge cycles at 1C/1C. Results...

Unfortunately it's actually a bit more complicated than that, what you have posted. That's the standard charge and discharge continual rate. It's is the rate at which they spec the cycle life. Since this is a more informative spec sheet than others, there is a useful chart much later on in the...

If you want to replace the old CALB SE400 cells there are still a few manufacturers out there that I belive still make the 400ah plastic cased cells. They are Sinopoly, Thundersky Winston and GBSystem. The hardest part will be sourcing them. Though as stated above GWL distributes the Thundersky...

I don't have a proper name really for you. I refer to them as laser welded studs as that is what they are and how they are attached. However what I can do is give you some of the cad drawings I found digging on Taobao for them. There are other stiles out there as well but I do not have drawings...

Two more datasheets and a switch from a scanned to a digital copy of the 52Ah

Also replaces the scanned copy of the 120Ah datasheet with a digital copy

It's interesting to note that they have given you a mix of different cells there, the ones that read as 280ah cells are definitely produced as 280ah cells (CB310 in the QR code) Attached you'll find the datasheet for them. The CB7C0 cells are new to me, if I had to take a stab they are are...

Seems like the wholes are placed ~22mm apart center to center. These were measured with some junk plastic manual calipers so I would round it down to a even 22mm. Holes are tapped m6.

Here is an official cad drawing from EVE for a 280K with studs. Come Monday I could probably get a copy of the drawings we did here when making a pack out of the cells. The datasheet with this drawing is now in the resources under EVE Datasheets part 2.
