Daly BMS gone crazy..Update Opinions

I was charging my 120ah lifepo4 battery yesterday and came in for lunch and saw it shut down..I figured it hit the 3.65 volt cell limit and shut down,I went out to check it and saw this on the Bluetooth for the BMS and it is locked up tight(The Bluetooth BMS)..I can't change anything and it only shows this on the screen..



The guy I bought it from first told me to reset it in the settings,so I did and he was supposed to send me the numbers/parameters to put in but he instead says he is sending my picture to the manufacturer for there take on it..After resetting I tried to just put in Lifepo4 as the battery type but it won't take it..

I would start asking about a replacement battery to have the features promised and paid for.

Yes,it did,but when it went whacky the rep told me to try and reset to factory settings and when I did,it went to nothing but 2's in the preset settings for the battery, example..cutoff at 3.65 volts is now 2,and is stuck on the page I first posted..it's pretty much toast right now and unusable...The battery works just fine though and is holding a charge..

I can't even start by choosing lifepo4 in the settings,it won't take it

Hi jacocreek,

It is still showing something that connects to a cell phone here:

Assuming you have the model with the accessible cells, you could consider switching the Daly BMS for a different and more reliable bluetooth BMS:
Overkill BMS
Also available for less straight from the manufacturer:
LLT Power

The nice thing is you get both control of the BMS functions (balancing, low temp cutoff etc) as well as battery capacity monitoring, so you don't really need the BMV.

Well, one option is if it turns out to be just a defective phone app, better off to seek an adjustment $$ and just get a Victron BMV 712 (with bluetooth) and just move on...My LFP doesnโ€™t have bluetooth, and even if it did it probably cheap so I doubt I could really rely on it ...JMHO

That's kinda what I had in mind..Either the Victron smart shunt or the 712..One of the reasons I bought this particular battery was the smart Bluetooth and the cold cut off,so we'll see how it plays out...There was another buyer,but on Amazon, that reported the same problem, but said the Bluetooth app went whacky when almost fully charged..lol

Thanks

The total ah does not confuse me and I don't remember anyone mentioning the difference in cylindrical and prismatic before on a thread I was on..

In my continuous reading about lifepo4 since I just bought one,I noticed BB and what they said about there choice of cylindrical over prismatic and why...I did not know that there was much of a difference other than what is stated on there web site which I have not found anywhere else...

I read here more than I post to learn from those that have had lifepo4 much longer so I have a better idea how they work and why,so I can understand my expensive step into lithium batteries and how they work best....

I started this thread to see if anyone had an answer or idea why my Daly smart BMS did what it did and the R&D man from the company I bought from said it was a hardware failure,not BMS and an update was in the making but,I just got an email from him wanting my phone number to explain it..I looked on there web page and all the reference to smart Bluetooth BMS has been removed so I expect a live with it or lump it conversation..Hopefully not..

Just reading on Battleborn,I noticed this comment made by them..

Weโ€™re also often asked as to why most lithium battery companies say not to bring their batteries to a full charge or below 20%. The batteries use cylindrical cells that can be drawn down completely. Other lithium batteries typically utilize prismatic or block cells for their chemistry. Avoiding the use of prismatic or block cells allows our batteries to have a longer life span and to achieve 3,000 to 5,000 life cycles.

Unless I'm misreading it,it suggest it's the prismatic that shouldn't be drawn below 20%..Kinda a diss on prismatic true or not..


its misleading. it is the chemistry that determins draw down not the form factor. form factor will determin how fast it can be discharged or charged as some forms are easier to cool, and a little bit of energy efficiency.

I am not totaly sure they know what there talking about either. what is a block cell? is he trying to say prismatic cells are not block cells, they are shaped like a block. I saw another threas where they called a type "prismatic pouch cells" thoes are two different form factors not one, there is the pouch cell which is flexable and has to be compressed or you can draw or charge at high rates, then there is a prismatic cell which is in the form of a brick and is metal incased, and clyndrical.

I already discussed the differences in another thread you were on but it seams that every time we show you how it works, you just pick a different thread and ask the same thing all over again. granted there is a new componant that may be confusing you so it is what it is.

some companies do use extra capacity some don't, whats so hard to understand about that?

now seperate that from when they advertise there voltage (pretend they didnt even say anything about the capacity) when empty the voltage is 10V when fully charged it is 13.6. thats pretty simple, it seams what is confusing you is they (or you) are combining two different facts. they advertise 100 usable AH, so even if they put more in is that being dishonest? as a consumer would you complain about getting more for your money? but you sure as heck would if they only gave you 90AH wouldn't you. you seam to be trying to vilinize a company for giving you a better product than you paid for.

I think you have lost all of us at this point....

I have no idea what point you are trying to make here or why. I would also be hesitant on using Battleborn as some sort of authority on lithium batteries, they are not a battery manufacturer, and outside the RV world (which they advertise to, heavily) they are relatively unknown.


The point is whether that BB has extra capacity or not, which was a question raised earlier by others. I was replying to that question.

The video's math shows it to have 102AH and it is rated at 100AH, close enough.

I think my calculations, including using the v/SOC table BB uses, confirm that video's calculations. The BB 100AH is indeed a 100AH batt with no extra capacity (AH or Wh).

Whether my answer to that question is correct would be of interest to the folks wondering earlier about the BB's capacity. So far nobody has posted any calculations one way or the other to answer that.
