Very impressive video. I ordered a new 280A 3.2 LiFePO4 today for $212 from Ebay as a backup for my 16 battery 24v system. My BMS on the 2nd battery pack always showed one battery low. I checked the voltage today and it was 2.0V. I pulled that battery out and running it on a balancer (all day so far). I pulled another battery to connect it together to balance it faster; the connecting bar got pretty hot for 10 mins. I think the battery is not broken, just needed additional balancing. Your video helped me on how to connect my 200A 8S BMS to this number 2 battery pack. Installing the BMS as a leg on the negative side!

Does these cells have to be in a box?
I'm only like10 minutes into this video and I can already confirm that this is the most helpful video I've found when connecting an 8s battery. Thank you! I feel that a lot of video creators skip over the "basic" stuff because they don't remember that they didn't understand it at one point. As someone who is doing this for the first time, it is very helpful.
Hi Ross. Thank you for watching and for your support. Your words really mean a lot, much appreciated. Thank you so much.
Oh brother, thankyou!
I am using a Daly Smart 48V 250A 16s, with 304 AH cells.
I just dint know what to do with P-. 😂😂😂
Then when I sat down, tried to calm down 😅, watched your video....the lightbulb went on, pardon the pun.
Okay, now I am clear, P- , is just that...its the negative. Oh my the relief you have provided me!
Just building my first batteries using basically the same components you did, so your video is so reassuring. Thank you.
He did it wrong! Don't plug the BMS plug in with the leads connected to the battery.... Plug the leads into the BMS, then attach each of the seven leads, one at a time to the battery - starting with the black and ending with the red. If they're already connected to the battery when the plug is connected, damage will occur to the BMS if the contacts don't make connection at exactly the same time and sequence.
Very nice video ,simple and detailed,I would like to ask how do you choose the BMS? I bought four 3.2v 300Amps batteries,and a BMS 4s 300Amps ,did I do good or I should choose the BMS amps according to my solar panel power which is max 100Amps and not according to my battery amp power?
27.6V is the float voltage and not enough to fully charge the batteries! The charger should be set to an absolute minimum of 28V and maximum (recommend) 29.2V
You have about the same setup as I have recently built. Have you done a capacity test on any of your cells yet? I have 16 of the lifepo4 varicore 310ah cells from AliExpress and have been running them a few weeks now. They came pretty much balanced voltage wise. I paralleled the 2 8s banks for about a day to make sure there wasn’t much current transfer when I built the 2 24 volt banks. I also want with the Daly smart bms 200 amp. My inverter has a maximum dc input current rating at 175 amps so I wanted to make sure both of the bms’s would give it what it wanted. I will be placing a 150 amp inline fuse soon to protect a malfunction somewhere. I can also set safety parameters in the bms to stop current at so much charge/discharge if I need to. I ask about your capacity testing because these cells have only been giving and taking about 290-300 ah so far. I hope mine aren’t used with lowered capacity. I could have done a test better probably also but I was hoping to get 310 or more.
Hi Joshua, thank you for your post. I have not had time to do a capacity test as I was trying to get everything installed in my Van. I think you are spot on with the 290 to 300ah. My cells were also fairly close in voltage, however, I did do a top balancing. I have set my parameters on my Growatt for a max charge of 28.2 volts or 3.525 volts per cell. So, I am not pushing them to a full charge of 3.65. Do you have a shunt setup? Thanks for watching.
Pretty useful info on this video of hooking these 310 AH high capacity cells correctly to ensure a safe way to charge them with a DALY BMS . This is a great video .
Hi Cedric Green. Thank you very much for watching and for your support and encouragement. Very much appreciated. Thanks.
Hi. I want to know that you did not tell us that how to operated the DALY BMS . Is it blue tooth enable how I can see the parameters . What's mobile app I may need for it.
How much current is needed to activate this bms
Hi Zoheb, I am not a 100% sure, but I do know that your lithium iron phosphate cells have to be at least at 3.3 volts per cell to activate the bms. Hope this helps. You can activate it with the transfer switch on the growatt itself by charging that way. Thank you for watching and for your support. Please consider subscribing if you found the content useful. Thanks.
Wow! Thanks for the info, I wonder if the batteries were delivered from China to the USA? I bought 8 battery cells, I have been waiting for 9 months ... „they will give birth soon“😅. please give me the seller's address
Hello,
Can I ask here Question?
Hi Salih. What is your question? Thank you for watching and for your support. Please consider subscribing if you found the content useful. Thanks.
Why didn't u compress the cells...
Hi Zoheb. I did a lot of research before and considered compression, but ended up not going that route as it was not necessary or would have made a huge difference. Thank you for watching and for your support. Please consider subscribing if you found the content useful. Thanks.
Very good
Wish I had seen this before I destroyed two cell from my 24 volts bank.
Thank you for watching and for your support. Please consider subscribing if you found the content useful. Thanks.
Very easy to follow. I just got my 8 cells and gonna setup like you.
Great video. Can i ask you why only a 100Ah only BMS? I am planning to buy the same battery setup and i am not sure what Amp bms to buy. i tought a 310A batery will need a 300Ah BMS Am i wrong? Thanks in advance for your answer.
Hi. Thank you for your kind words and encouragement and for watching. I chose a 100 amp BMS because that will provide at 24 volts, 2400 watts of power. I may upgrade that in the future, but should be sufficient for my needs at the moment. The math works like this, very simple. To determine what size BMS you need. Volts x Amps = Watts. So in my case 24 volts x 100 amps = 2400 watts. If I wanted to use my full capacity of my 3000 watt inverter, I would take 3000watts/24 volts = 125 amps.
I hope this is helpful to easily choose what size BMS you need. Thank you for watching and for your support. Please consider subscribing if you found the content useful. Thanks.
I doubled my BMS size. Runs cooler. Cheap stuff from the other side will not put out to specs.
You can give more details about that bms. I am interested in buying a similar one to equalize the 24v s8 320A. Thanks
UMMM INTERESSANTE IL VIDEO,ma non usi un bilanciatore attivo ? ilBMS serve solo per proteggere la batteria da HIG e low ,quindi visto che sono gia' in serie prima di caricarle dovresti collegare un bilanciatore attivo ,alrimenti potresti rovinare le celle
I am using 310 amp hour cells in my bus build. I got them from LItokala and it took about 7 weeks to get. I got 16 cells in a 2p8s configuration. I went with an ANT BMS as it has functional cold temperature cutoff where all the Daly ones that say they have it that I've seen tested [Will Prowse's channel] don't seem to actually shot off below freezing.
Nice man and good luck with your battery build. Its very exciting to make your own power. Thank you for watching and for your support. Please consider subscribing if you found the content useful. Thank you.
I have a ready Made Battery 24 volt 200ah and the bms wires are on the minus terminals of the battery's the wires are white apart from one being red going to to the positive and the other is black going to the minus why is this? when the above are on the positive there 8 cels and 50 watt each. can any body tell me why? as i need to change my bms and it is broken. bms not the same as the above.
is the last cable of the BMS connected to the inverter . I noticed the last cable not connected to the last terminal on the bank ? awesome vid thank you i Leart a few things here
Thanks for the video-nice. I'm in the same process of making battery. I ordered 8 - 280ah cells but I will be using the Electrodacus bms. This will also be used in my van camper. Waiting on cells!
Hi Greg. Thank you for watching and for your support. Its very much appreciated. That is awesome that you are doing a camper van. The hardest part was waiting for the cells, 😁. Mine took over 2 months to arrive. Good luck and let me know if you have any suggestions. Take care.

Hello najs video 👍 are you pleased with the daly bms? Can you trust it and leave it be? Whats the maximum current you can draw from a 8s 24 v system of 310ah eve? And what is the Max current you can charge them with?
Hi Andreas. Thank you for watching and for your support. Yes, I am very pleased. It charges at 50 amps and I can draw a 100 amps at 24 volts which is the equivalent of 200 amps at 12 volt for a max of 2400 watts on my inverter. Please consider subscribing if you found the content useful. Thank you.
The temperature sensor should be on the side of the battery, never the top. There is an air pocket on top, it won't work properly like that.

How do you hook up a solar controller and inverter with this set up? Why would I need a charger? The whole point is I want to use solar?
Hi Dennis. Thank you for watching and for your support. I understand what you are saying, I had the same questions, the issue is that you need a bench top power supply to get your batteries higher in voltage so that it can wake up your bms and start your inverter. You only need to do this once. You can return the bench top power supply after that. Hope this helps. Please consider subscribing if you found the content useful. Thanks.
Also the bms can get very warm I would not tape it to the outside of the battery.

Greetings excellent video but I have a question about the configuration of charging the batteries, what would be the numbers for mppy Float voltage and absord voltage?
Hi Jose. Thank you for watching and for your support. Great question, it depends on many factors including your battery chemistry. If you have a lifepo4 battery and you don't want to fully charge it to 3.65 volts per cell because you want your cells to have a longer life. I have my bulk voltage set to 28.2 volts (3.52 per cell) and my float voltage set to 27.6 volts. But with lifepo4 float is not really required, these are really parameters for lead acid batteries. My inverter has a setting for lifepo4 and the bulk and float are locked together, so whatever you put your bulk to the float will automatically be the same number. Hope this helps. Please consider subscribing if you found the content useful. Thanks.
nice video thankyu ...
Yes on the voltage I’ve heard 90% which is about 3.33v to get longer life then charging up to 3.65 and don’t drain you’re batteries down to 2.5v DIY Solar !
Hello and thank you for the very helpful video, are you using a circuit breaker and shunt between your 24v battery and 3000w inverter? If so how many amps should your circuit breaker be, which shunt would you use and how would you configure it?

Great video. Curiosity question. Your cells are 310 AH and your BMS is 100 a. Shouldn't the BMS be at least 310a. Thanks.
Hi Kevin. Thank you for watching and for your support. I appreciate the feedback and that is a great question. So the way to pick your bms, size your bms for the amount of watts you will be using divided by your battery bank voltage. In my case for example, I have a 3000 watt inverter and a 24 volt battery, so 3000/24 = 125 amps. So I went with the 100 amp bms because it was half the price, but it also means that I must not exceed 2400 watts (100 amps x 24 volts = 2400 watts. At some point I will buy a bit larger bms so I can run the full 3000 watts, but rarely does one use everything all at once. I hope that makes sense. Let me know if you have any more questions. Great question. I also struggled with this one at first. The Ah is really just the storage capacity of your batteries. Take care. Please consider subscribing if you found the content useful. Thanks.

Can I connect P- to victron mppt negative side
That helped a lot. Was lost, tnxs a lot sir!
Yes it was very helpful.
Why don't u just test the very last one because if it wasn't wired correctly u wouldn't get 26 volts?
Great question Linda. Actually the checking of each one ensures that you got all your bms leads on each cell positive in the correct order, for example you may put your last lead on the correct cell positive, but maybe 2 and 3 are switched by accident. Then on cell 2 instead of getting 6.6 volts you will get 9.9 volts because 2 and 3 are switched by accident, but the last cell will still read 26.4. I hope that makes sense. If you would connect your bms with the order incorrectly you run the change of the bms burning out. Thank you for watching and for your support.
test them all, only takes 30 seconds and ensures no crossovers, crossovers still will show 26. after all the effortinvolved, you are querying this step?
