Dude, THANK YOU. I was losing my mind trying to get this to work, but the one tiny detail you mentioned about how it won't turn on without the temperature sensor was the one bit of information I was missing. Really clear and to the point guide - you saved my butt!
Great video. But i would recommend to tel the subscribers that you should ALWAYS top balance the cells 1st before connecting the bms. I myself have burned 2 daly bms because i did not top balance my cells.
Hey buddy good job man so hard to find a simple direct short to the point directions and the activation tip to turn bms on is sooo criticall for newbees like me 😊😊😊😊😅😅?!.,
Thank You from me too! I was trying to get my system going as well but the instructions were in Chinese. I purchase the touch screen display as well and nothing worked! I will give it another go with the info you have provided!
When you setup a BMS balancer cables, they all go on negatives with the exception of the last one that goes to positive. Balancers only balance by the negative cable. Will be better to explain that goes to B0, B1, B2, B3 and B+. Nice video.
We tried a Daly LiFePo4 8S 24V 100A BMS with a Epever UP3000-M6322 nothing no lights on so ordered another unit assuming it was dead. The trick of shorting the B- P- together briefly did it so we now have two Daly BMS's short spark when shorting but expected that now I need to adjust Epever setting as I had lead-acid leisure batteries before. Thanks for the hint
@@littlebill2601 it does come with the main leads and balancing/cell voltage leads. I ordered mine from the current connected store and it also came with the Bluetooth module, hardwired to USB connector and the temperature sensor. Also the gentleman who runs the store is excellent, would highly recommend buying from him.
It allows the inverter to turn on and kick into "charging" mode, if the charger didn't see battery power it wont turn on. Then, when I stop touching them the power is re-routed through the BMS to activate it.
Excellent video and very clearly explained in brief. We connected the balancing terminals to batteries, NTC is connected. We shorted the P- and B- terminals and tried to switch on the supply of 60V for a 52V Li-ion battery, 100 AH for around 6seconds. Still we are unable to charge the batteries through Daly 16s BMS. Any inputs please.....
Even better than folding those fine wires, you should apply Ferrules to them appropriate to the wire gauge, then crimp the ferrule in the ring terminals. Much stronger. Ferrules should be used on all wires that are compression fit for a grab, instead of on bare wire. I just did my Daly BMS wires and the ferrule/terminal method worked great to where the heat shrink on the terminal grabs the plastic of the ferrule.
Hi and thanks for this useful video ! I wanted a battery with the best BMS, so I chose one with a Daly Smart BMS 4S 12v200A (with bluetooth). But the battery can't charge. So I opened it. And I saw that one connector was the wrong size. It's the connector with 4 red and 1 black. When I connected it correctly, the battery screen was finally on (68% of charge). But the battery still not charging. And no bluetooth. To initiate the BMS, I tried to connect P- and B-, and the charger turned ON. But when I stop connexion P-/B-, the charger turns OFF. Do you think the BMS is dead ?
This is a great video of a simple setup, however I am stuck on the part as to where my solar charger comes in. I do not have a all in one charger and inverter. How should I wire the solar charger to my BMS and at what terminals on the battery pack? Do I just use the same terminals on the battery pack that my inverter is bolted down with?
Great video. After watching it I bought a 50a version of the same bms but after setting it up I notice that all it does is monitor the state of charge and temperature essentially. it does not balance the cells and does not cut the charge current when it hits the overvoltage protection level. does it require additional configuration for it to run properly?
Great Video! Straight to the point. I am curious though. I would like to put my 200Amp Daly Bms inside of an enclosed battery box. Does anybody reading this have any real world experience with heat from the BMS. It looks like it is intended to have air over it?
Hi nice video ...i need a help i have online UPS which requires 192v to run which bms i should use for such pack ...i googled i came with information of can bus bms ... But i can't understand it properly ...can you make video on that
Good evening CC... I have an unrelated question that you may wish to answer..? I have two solar generators and would like to power both at the same time using one 180 watt solar panel (instead of a separate for each).. Realizing that the sogens cannot be connected together in any way, my solution would be to provide the necessary branch mc4's for each sogen and isolate each branch with an inline mc4 fuse which already has the diode built in to prevent vdc back charging. Your thoughts..??
I think one unit will pull down the voltage to reach maximum power point, then the other unit would fight with the first unit. Your best bet is to try and feed the solar into one generator, then plug the ac power input from the second one into the first one. Try at your own risk, but I don't think your idea will work very well.
@@CurrentConnected I know of the normal way to connect two sogens. But, I would use the vdc blocking diodes (already built into the inline fuses) to prevent vdc from being fed back into each leg of both positive leads of the two mc4 branch legs so that vdc cannot be swapped across the branch, the same as bms does between the solar panel and battery, or solar panel into a sogen....
Hello... I am currently in the process of connecting a 200 amp Daly bms to a 340 ah battery bank that is connected in a 2p4s configuration. I had the same issue as you where the voltage of the P- wire was around 9 volts where as the battery bank is 13.20 volts. Is that normal ? According the to Daly instructions the voltage at the P- wire is supposed to be the same as the B- wire.
I've done all these are steps and can't get the BMS to wake up. Could the temp sensor calibration be a reason that it's not waking up? It was 36 F outside during my attempt. My inverter powered up with a load but when I removed the bypass jumper between B- and P- it shut down. BMS app isn't seeing BMS. Voltages on balance leads are good. Temp probe and uart Bluetooth connected securely.
What is the default low temp disconnect value? I have heard -7c is that correct? Is that a good number for LIFEPo4 Chemistry? Have you had any luck updating the low temp value through the bluetooth app?
To my knowledge, updating any parameters through bluetooth is not possible, but they certainly can be changed through the USB-UART cable. The low-temp setpoint has various that typically are out of whack and require programming through a computer.
@@CurrentConnected I have a Renogy Rover 40am MPPT Charge controller now. So if I connect it to the battery bank after all these other wires are connected for the BMS, will that damage the BMS?
i activated the bms by charging the battery and bms. Then i could find the Bluetooth connection in the Phone. but now a few hours later i cant connect to the bms with the Phone. Do I have do activate it everytime to connect to my Phone?
Hello, I have a siliar situation, my charger does not recognize the battery, it marks an error because it detects too low a voltage. Can I connect B- with P-? That can activate the BMS without connecting the charger yet? Thanks.
Connect the charger to P-, touch together P- and B- so the charger sees voltage and activates, then once the charger starts up stop touching together B- and P- and the charger will continue charging, and it also will already have woken up the BMS.
Hi, I have a brand new DeliGreen 8S 24V 150A, and then follow exactly the same steps as on your video, but NO SUCCESS, I repeated it again and again, still with no success. Tried some other ways (checking the resistant between B- and P- to get 0 Ohm, also did not success, never get 0 Ohm, always showing somewhere around 300 Ohms). The BMS still won't activate. My battery is around 26.74 Volt, is this voltage too high for the charger? I have tried to charge it with 30V, but still no success. Can this be a faulty BMS? How many volt should I charge the battery, if the battery is still having 26.74V. Is 30V charger not high enough, to activate the BMS? In may case, on the last steps, if I unplug again the power from the grid, then the inverter will switch off and will not take the electricity from the battery... (because BMS is still not active = B- to P- still has around 300 Ohms).....
I have a bad 4s12v Daly BMS that has the exact symptoms yours does. I tried for a hour to “wake” to no avail. I also made sure everything was connected .I.e. temp probe. Solar power is not a poor mans sport. Buying a new high quality BMS would add 6 months pay off time to my DIY system. SUX
When i was wiring my bms i measured the voltage of the battery and it was 54.0 volts (13s battery) then i connected the bms wires, everything was fine, 1 =4,15 2= 8.3 and so on, but when i soldered the b- to the - port of the battery and measured the b- port and the + port of the battery it showed me 25.5 volts... i dont really know why... maybe you can help`?
I noticed when the voltage of BMS is lower than battery voltage? The BMS is not turned on. Must have charge current on, after shorting B- P-, try pushing the blue tooth dongle switch, was also told you can try to run a jumper from pins 1 to 3 where the light board plugs in. I'm guessing the light board has a momentary switch that acts as an on off switch. Instructions are horrible from Daly.

They barely ever get warm, even with sustained heavy loads. Unless you are getting to 300a+ levels, you really don't need much airflow.
