Thank you for explaining these BMS. I got my new 8S 24v 200 amp BMS today in the mail. It had zero instructions with it. After 3 hours of looking around - I found your video. I wanted to personally thank you.
If I am making a 24V battery with 8 cells is it best to connect them all in series? Or should I pair 2 cells each in parallel and then connect those 2 cell pairs in series?
Thanks for watching, connect them all in series. +-+-+-+-+-+-+-+- use a 24v BMS and wire it up like I did with a 12v but carry it along. Remember to size your BMS to your application.
So the red cable coming from the battery positive will go to your inverter positive and then you have a shunt on the battery negative side from the bms negative and then that connects to the inverter. Is that correct?
I am wondering if I can use a 200 amp 16s.BMS on a for cell battery pack! Daly does not communicate and their English manuals might as well be in Chinese.
Thanks for watching. Sadly this will not work. Reason being the BMS will sense no voltage on 12 of it's balance cables and shut off. You need to use a BMS to match the battery. Ideally a BMS no more than the battery. Example being a 100ah battery to a 100amp BMS. Reason being it's not ideal to drain a battery higher than 1c on them cells. Causes battery stress and lowers their cycle life. 0.5c is good. Google battery c ratings for more information. Hope that helps.
Hi Chris. Thanks for your excellent video. It was a great help wiring up my Daly Smart BMS. One question with regards to the Daly. At what voltage does it start balancing? Can you change that voltage?
With a wire in balancer, it's 0.1v difference between the cells with a 1.2a current balance. I suspect it's the same with the Daly one. With the bluetooth BMS's I've noticed you have a lot more control over the smaller details like cut off and balancing voltages. I have a video on the balancing PSB. I actually leave one connected with the BMS also. It's not used, I don't see the balancing LED's come on which is good on the solar shed setup.
@@SolarPowerChannelwithChris Thanks Chris. I will see if I get any smarter with the Daly BMS when putting the pack together in Series. I had it in series when charging the cells up to 3.4 V before going parallel for top balancing. Could not find any settings for balancing voltage levels. Perhaps a topic for your channel “how to install and use your Daly BMS”
@@CG-xr5bz hello, I already have a video on this. The settings are pretty much good and you don't need to mess with anything. ruclips.net/video/1EpHGK-Un0U/видео.html video here. These are my personal settings from time to time. Regardless of battery size, they are all the same. Hope this helps.
Hi just wondering do you work from left to right with the battery configuration or it doesn't matter as long as you following the wiring diagram correctly?
The balancing leads correct? Deffo connecting red wires on to the + cells. As the BMS will stay off as it's noted a cell looks to be low in volts. Hope you don't have a faulty BMS. You connecting an inverter? The surge in charging capacitors can also trip the BMS.
My Batteries and my BMS have arrived from China finally yesterday. I have tested the 3.2V 280 amp cells. All 4 cells are all exactly 3.2V When I hook them all 4 in series they show 13.1V. I received also a Smart Daly BMS 4S 12V 100A (discharge current 100A, charge current 50A, communication interface BT and UART it says on the unit). Daly electronics RO5A-G805. My MPP solar unit is an "all in one" (includes converter & charger, It is a PIP-1012LV-MS 1000W 12V 120VAC solar inverter + 40A MPPT + 20A charger from shore power or generator. (I included a link to the web page last time, so that may be why post was removed or it did not post). I have the system set up in my motorhome. 600W solar panels. I have a small 120V AIR CONDITIONER unit hooked to the inverter in the PIP. This unit should be able to drain the new batteries in 4 hours or less, to test the bottom balance, if needed. This A/C unit draws a bit less than 6 amps at 120V. (as I have 600W solar I would do battery draining after sundown, I guess) Because the BMS is smart should it give me all the info I'll need? Based on all of this info, how should I proceed. All that I know about all of this is what I have watched on RUclips. Thanks for your time and patience. Do I even need to bottom balance or will the BMS take care of that?
What is the bms connected to I see a black and a blue wire going somewhere? is this a charger? or are you not charging to top balance? please elaborate. Sorry I am so uninformed, but I am setting up this exact setup for my solar motorhome, when my cells and 100amp bms arrive.
Thanks for watching, the blue cable which is B- will go to the battery negative. The Black cable will go off and feed what it needs to in your camper. Think of the BMS is a inline automatic switch to safe guard your cells should something not be right. Something lead acids should of had I think years ago. Hope I have answered your question. Also remember you will need the correct charger on your camper to charge the LiFePO4 cells, a DC DC charger. You cannot charge straight off the alternator. You in the UK?
Half of my post didnt print??? anyway I expect the cells and the bms to arrive this month sometime from china. Could you walk me through what all I should do to put my system together. I am pretty handy. I have a stupid amount of self-confidence I guess you might say. I have built houses cars, invented things that i sell (see youtube chanel) even made a starwars bike for my grandchildren. I have a simple volt/amp meter. not sure if I require other tools.
Hello, Thanks for your video. I have a BMS DALY 4S 100A spearate ports. How can I connect to this BMS? There is no port to add a bluetooth module. I want to change the cut-off voltage from 2.2 to 2.5v. Thank you for your help.
Hello, if you are connecting an inverter for an example. You connect the negative to the BMS (P-) then the positive to the battery positive. Please watch this video, at the end where I connect an inverter to the battery. ruclips.net/video/SJn9_9Hihyw/видео.html Hope that helps.
I was wondering what the difference is between a BMS and an active balancer? If you have fuses protecting the battery and a charger with a profile for lifepo4 then why use a BMS? What is the BMS actually doing?
Few reasons, low voltage disconnect, LiFePO4 really don't like being dropped below 2.5v per cell. Also high voltage disconnect, over 3.6v. A balancer is not strong enough to pull a cell voltage down or up to match the others. You may find 3 cells at 3.4 and the third being hammered over voltage. But the charger won't see this. Just over all voltage. The BMS will disconnect and safe guard. Also temperature, low and high temperature. Below freezing will destroy a LiFePO4 by what is called lithium playing. A BMS will cut power until the cells warm up. Electric cars get around this and battle born batteries for an example. Warm the batteries before charging. High temperature disconnect, protecting against damage and fire. A balancer normally only balances at 1.2amps. please see my video as I try to explain. ruclips.net/video/-1fXgF37qz4/видео.html
Hello, thank you for watching. You base your BMS on what you are supplying. The amp reading on a BMS is what its drawing from the cells. Not the size of your cells. Your not the first to say this. What do you intend to use your battery pack for? If an inverter I would need the wattage. Thanks.
@@SolarPowerChannelwithChris , Thank you very much for your quick response to my question, it is now very clear to me, I want to mount an electric motor on my fishing boat of 45 lbs which uses about full throttle 40A so I will mount a bms of 60A or 80A then it is also suitable for a slightly heavier electric motor. also thanks for explaining in your video, very clear,Thank you
@@jos9678 no worries, please see this video in building a battery in a small box. ruclips.net/video/IJBRdWxnt_w/видео.html another one of mine.

Thanks for watching! Sounds like your cells are flat maybe at 9.6v. That is the cut off voltage for your BMS. Its very hard to comment without seeing. Hope your have fixed your issue.
@@SolarPowerChannelwithChris Hi Chris thanks for the reply. Much appreciated. All cells are 3.29v pack voltage is 13.1v. I connected a charger to the pack. This seemed to start the BMS as the Bluetooth app is working
Oops hadn’t finished typing. I now have 14.64v out of the bms but no current. The app is pretty useless at allowing changes to parameters and is displaying some alarms which persist after reset reboot and reinstall. Thanks again for reply.
I’ve got the same cells & BMS pretty much but I’m running 48v 15 cells 3.2v and I’ve recheck multiple times all are wired properly voltage is 49.5v positive to negative & positive to the blue cable 49.5v “ my question is “ “from positive to the Black Wire off the BMS reads only 38.8v ! I have not arced it out , my Bluetooth on my iPhone & on an Android does not read the BMS i have downloaded SMART BMS & 123Smart BMS neither work with this Smart Dali BMS ! I took pictures of all
All the balancing cables definitely connected to the cells? I had an issue with a connection once, was giving me trouble! The BMS maybe off at 38v which is why the Bluetooth is not on, you cannot pick it up. Noticed mine shuts off.
First time to connect a BMS.This video helps me a lot.Thanks.

Nice job.
Great video, clearly explained!
Bingo! Ive been looking for this since i dont have knowledges connecting my bms. Thanks a lot Chris

Nice tutorial bro tnx a lot
Thank you sir
How do I know what cell is the first cell? How do I know to start from the left or right when installing the small wires?
Hello it's the same ion battery bms ?? Thanks
So the red cable coming from the battery positive will go to your inverter positive and then you have a shunt on the battery negative side from the bms negative and then that connects to the inverter. Is that correct?
What ring connectors are you using on your balancing wire?
Just some from the local hardware store, has them for ages!

how is the charger connected? Can it be wired in parallel with the P+ and P- wires?
Yes, you got it. Charger positive to positive on the cell. The negative charger to P- on the BMS. Use the right voltage charger.
👍 Well explained, subbed 🙂
This will be useful

Thanks for watching, they are all pretty good really. Always good to get one with a bluetooth. I always leave links to stuff in my video comments.
How would you build a big 12 volt battery bank. Would you need a bms for rack set of four cells
If your building like I did with LiFePO4 cells with higher capacity, yeah.
Then how would I connect the two batteries and the two bms together if you don’t mind
What would the settings be for lifepo4 12v 280ah please? 150A Daly.
