Thanks a lot for sharing. I have this BMS and you did a great job of summarizing the settings. Just a note about something I saw in another video. If your BMS isn’t charging or discharging, make sure to hook up the temperature sensor. I didn’t realize that it wouldn’t work without it. (I live in Hawaii so I didn’t think it would ever get too hot/cold.)
Hi Chris, thank you so much for sharing! We're in the process of converting from LA to LifePO4 batteries on board our sailboat. I bought the daly bms as well and I was wondering about the setting. Well done!
Hi Chris, Thanks so much for the video, I'm currently day 1 on the solar build and was baffled to what it all meant! ! question, IN the "CELL CHARACTERISTICS" menu, I can set the SOC set manually, but how do i know the SOC and will that effect the the charging top and bottom limits?
Also in your case the “factory reset” button does not work and is deactivated? just like the "firmware update" button which doesn't work with code 123456? Use Daly smart BMS 150a 20s
Great video but I have a question. I have lithium ion polymer battery packs from a Hyundai Ioniq 2019. My question is, if you have no idea of the capacity of the cells, like I don't, how can I set any parameters. Luckily the packs are all 48v 12s. I have asked on forums as to how to test a pack to see what it's capabilities are but how can I when I don't know what 100% charged looks like? Any advice would be great. Keep up the great work 👍 David
Thanks for the video. I'm assuming these settings are for a stationary solar battery? What settings would you recommend for a 15s battery that replaced four 12v AGM batteries for a Ryobi zero turn lawn mower? I had 100Ah on the four AGM batteries and this new custom built battery is 100Ah also. I was thinking I would set it to charge to 90% and stop at 10% SOC to preserve the battery?
Balancing at low voltage does not help due to low balance current and high charge current. The effect of small balance current is only effective at steep charging curve probably at 3.45v
hello wonder what is the range of cell high/low protection on these ?.. mean to say wonder can these be setup for li-ion as they have slightly different voltages ? TIA
excellent video, congratulations. It inspired me to build mine. But I have a question, if in charging the bms receives a load above the maximum, what happens? for example it can charge 100a and receive 150a. Does it charge the 100a and ignore the remaining 50, or does it shut off and charge nothing or does it burn out?
Thanks for watching. Good question, I don't know. I've always thought it may burn the BMS out. A question to the manufacturer! I do say, don't take it to the 100amp. If your pulling that, get a 140amp BMS. Size up.
Thanks mate! This vid was super informative and helpful. Will be looking at the one about looking after the battery. Just one question. Will the BMS shut off charge at the cell voltage you set, even if you have the charger on the battery attempting to charge it. I’m wanting to keep my battery under 90% and hoping this BMS can do it. Cheers from Australia.
Thank you for watching. Yes, the BMS will cut the power once the voltage you have selected has been reached. Also low voltage disconnect. Note there are BMS's on the market where you cannot adjust the parameters. Enjoy your built! Chris
@@SolarPowerChannelwithChris thanks mate! I’ve actually ordered a lithium battery through a local company and they install this BMS. Do you know if they could lock the BMS so that you can’t set your own parameters?
hey, i have a standard 280a 12v 4 cell pack, i noticed my daly app now has an active balance section with a load of settings, it shows as having 2 battery strings, is this correct as cannot find any answer online, ty
If you turn the battery OFF with the discharge switch from the Bluetooth application, after a few minutes you cannot wake the battery on again cause of the sleep mode of the application. You have to put a load on the battery in order to wake the BMS up or have one of those red battery capacity external switches that has a power button on it in order to wake the battery up again. Is there a trick to this to wake the battery from the application or disable the sleep setting?
Good question, no it don't limit the current. Renogy has an alternator charger which also alters the voltage to match the battery. Charger has 4 settings, case of moving a switch. Link here for the DC-DC converter. amzn.to/3n3kPeu
I have a scooter that runs on the 60 V battery I recently installed the Daly. My scooter can run on single or dual motor. I noticed when I switch it to dual motor and quickly accelerate it dies out and won’t turn back on unless I wake up the battery by unplugging it and plugging it back in. Does that have anything to do with the Daly because the surge of voltage is being used suddenly. Do I need to change the settings?
Hi Chris, nice video ! I'm trying to connect my Daly to a motor and the app shows that there is a fault with the short circuit protection. Could you please help me?
If we charge the battery With a 60 watt 12 volt solar panel directly through the Smart BMS without having to have a charging controller, is it possible? Normally, how many volts can the Dali Smart BMS withstand?
Hello I have a lifepo4 battery pack connected to a 40A DC DC charger in my car. When the car is on the battery chargers at 22 Amps, but I want it to charge at 10A. DO I go into the setting and change the "over current protection" to 10 Amp?
want to know more about Sleep time setting? Set by default at 3600S is 1hr if the S stands for seconds But what it does exactly? when the timing starts? What functions are going to sleep. The app will not work! anything else? can it be disabled? what if it stays activated? how to get it out of sleep mode? Why it is needed? My the BMS not stay on continuously? Much questions for something what seems not important.
I have 4 lifepo cells 280ah total and they have gone incredibly out of balance. The balance doesn't seem to work, despite setting these parameters. It would be nice if you did a video of how the balancing works, showing it working. Also, does it need to be charging when it balances or does it do it when it rests? I cannot fathom how a company can put out a piece of hardware that is seemingly so complicated (and you can actually damage your batteries with incorrect settings) with no manual. I would never buy one of these again, that's for sure! Thanks for the video.
I have two 120A Daly w/ Fan and Bluetooth. I don't think they balance, I watch, configured and even tried contacting them. They responded once. I gave up and installed an active balancer and "disabled" the Daly via the app. POS. I also have a 200A Daly installed, I better check what's going on w/ that one.
Hi Chris I reduced the setting for balancing down to 2.5V but balancing is off. The battery is above 90% SOC. The balance diff is 0.05V, but the diff volts is 0.03. I set the balance diff to 0.02V and the balance turned on. Yay! It won't set to 0.01V though. Could I turn off the solar and change the settings in some way to enable me to use the BMS to read the capacity of the battery by allowing the battery to discharge until a cell reaches the minimum voltage setting?
The passive cell balancing on the Daly is useless, it can only shave off 20mA off the highest cell, so is pointless. If you top balance your cells to 3.6V and they are all the same age and internal resistance then you will not need cell balancing for a few years till the cells start to degrade. To preserve your cells set max cell charge to 3.5v and low cell discharge to 2.75V. I'm not sure how the Daly understands SOC. Most BMS use the cell voltage for SOC which is highly inaccurate for LiFeP04 as the difference between 20% and 80% is 0.2V. Best to put a shunt on your battery to determine SOC.
@@bildad1234 I've got a 3 bar radiator and each bar takes 500W (pretty accurately). So that's a pretty good shunt I think. My cells were out of a used home made EV. It's likely they are not uniform SOC. It should be 10KWh but I suspect it is down to about 8KWh.
@@bildad1234 16 LFP cells 48V. When new 200Ah. I'd rather measure KWh than Amps. The BMS gives Wattage continuously, but there is no cumulative calculation of KWh unfortunately.

my jbd bms has lost the setting and i have no idea what to put the batteries i have are 280ah and have 8 of them and want to run a 12v system with 2 bms units
Have you ever seen problems with sudden SOC loss as read by the BMS? My batteries some times randomly drop to like 14.4% but the voltage is spared then they'll only charge to say mid 60%. Clearly something has gone wrong. The battery manufacturer is in China and the help is a bit dubious.😢
@@SolarPowerChannelwithChris hi mate many thanks for replying. In order to discharge the battery to say 2.5v per cell I assume I need to get rid of the DOD on the inverter and run a load to failure like my pond? Shame you cannot post pictures on here like twitter. Very much appreciate your expertise
as far as i have read, the bms will only start to balance at a charging voltage of 3.5v. if the cutoff is lower, then it wont balance. is this your experience?
This has been my experience with them using the Daly BMS. Mine only seem to start showing balancing at 3.4v and that only starts balancing when they are almost fully charged making it pretty pointless really.
I get a locked Daly BMS app, cause the app is saying it needs a Software Update, and all options are locked out. It says it needs a secure firmware upgrade code? Any idea?
For individual cell protection high voltage setting, why is Daly BMS set to 3.75v by default, if going above 3.65v may damage the cell ? I have a non bluetooth Daly BMS and I read everywhere its individual cell charge protection is set to 3.75V.
@@SolarPowerChannelwithChris Thanks for the response. That's a Daly BMS for Lifepo4. Unfortunately not bluetooth so there is no way to set those. They are made like that, and that's in the specs. I'm a bit confused and reluctant to use it.

Hy Chris..." i want to ask you about lifepo4 charger, i use a Led power supply 30A to charge my battery, i set to 14.2V. It work approximately a month. But if i use 20A,15A that output current never stable. Recently my 30A Power supply have same problem. every second alternates from 7A to zero. But that power supply i can use for my amplifier. I use daly bms. Please help me for this problem...."
LiFeP04 charges with a simple CV/CC algorithm. At 14.2V each cell is 3.55V. So as you get closer to fully charged the current will reduce because for current to flow it has to flow from a higher voltage to a lower voltage. So lets say you have a discharged battery at 11V and you charge at 14.2V /20A. Your battery will take all those amps until it starts to get full. Once you get to 13.4V or 3.45V per cell your battery is pretty much full but because the voltage difference the current will be much lower. A designated LiFeP04 charger will BULK charge till it sense the current drop off. Then it will just feed in a constant voltage with low amps, this is called ABSORPTION. Once battery is fully saturated it will shut off all charging and enter into Float. Why your power supply is fluctuating from 7A to 0 is a bit of a mystery? How are you measuring that fluctuation?
If you have trouble following his quick speech and accent, switch on the subtitles. The SOC bit wasn't entirely clear to me, but it sounds like you wait until your battery is full then set the SOC at 100%. Anyway it's much better than the standard Chinese gobledygook.

Thank You very much !!!
You did this completely wrong. You maximum should be 3.65. Your charge controller/inverter should be set to your desired levels of charge. No one want there bms shutting off everytime there batteries reach desired full charge levels.
Hello, not all charge controllers you can change the cut off voltage. Which is why you do it on the BMS. Yeah 3.65 is maximum, but I don't want it there for reasons I said. It was my personal settings, it's to show people they can change. Having lithium fully charged stresses the cells, and keeping them fully charged and on standby.
@@SolarPowerChannelwithChris I install solar for a living. In mostly offgrid situations. Iv installed everything from eBay equipment to sol ark high end equipment. I carry a 5.0 rating. And call you most and I mean 99% of them have adjustable settings. Even if there's no setting for lifepo4 you hit a safe range leaving on agm or lead acid. Your literally setting people to have there bms shut there whole system off at full charge creating more head ache for them.
@@KenWarnersniperperformance yeah, I do hear you. I tweak my solar inverter chargers to cut out on a set voltage. I talk about this when I showed a review on a Renogy product say a few months back. But using a standard mains charger on your camper or caravan as a weekend warrior. The mains chargers cannot be programmed. Its just a way of having control.
@@SolarPowerChannelwithChris awesome. I'm glad you took my comments as constructive and not like I was trying to run you down. We all learn new things everyday. It's important we start our day looking for those lessons. God bless and keep em coming bud.
If your charger cannot be set for an appropriate lithium profile (the gel setting on many lead acid chargers is OK) a new charger is needed. The bms shouldn't be used to control the charge voltage, serious problems, even damage can be caused by doing this.
Thank you. I’m very happy to see this is configurable by the customer. I had trouble finding this information elsewhere.

I brought an mgod 13s bms from aliexpess,it never worked,ie no phone or pc coms or output,was like this out of the box,mgod have realy helped,just messed me about for over a year,no replacement or refund,just told me to buy a new one at my cost!,total shit company,best avoided!!.
Hi, should i leave the BMS voltage setting at 3.65, I have a victron 712 shunt and will set this at 80-20
Hello, yes you can leave it at 3.65v.
Have You Done a Mistake ??? ... "Diff Temp Protect = 255°C" ?????????????? Please !
That is what was already set. I've not touched that. High I know lol
@@SolarPowerChannelwithChris On my Daly 150A it was initialy notice 15°C. Strange for yours !!! Sincerely ! :) Have you seen my other question below ? ---------> Second question : 😁 Why your Cell reference volt is 3.60 V ? and not 3.20 V. Please ............. Your video gave me goods advices. Thank You very much !!!
You did this completely wrong. You maximum should be 3.65. Your charge controller/inverter should be set to your desired levels of charge.
No one want there bms shutting off everytime there batteries reach desired full charge levels.
Hello, not all charge controllers you can change the cut off voltage. Which is why you do it on the BMS. Yeah 3.65 is maximum, but I don't want it there for reasons I said. It was my personal settings, it's to show people they can change. Having lithium fully charged stresses the cells, and keeping them fully charged and on standby.
@@SolarPowerChannelwithChris I install solar for a living. In mostly offgrid situations. Iv installed everything from eBay equipment to sol ark high end equipment. I carry a 5.0 rating. And call you most and I mean 99% of them have adjustable settings. Even if there's no setting for lifepo4 you hit a safe range leaving on agm or lead acid.
Your literally setting people to have there bms shut there whole system off at full charge creating more head ache for them.
@@KenWarnersniperperformance yeah, I do hear you. I tweak my solar inverter chargers to cut out on a set voltage. I talk about this when I showed a review on a Renogy product say a few months back. But using a standard mains charger on your camper or caravan as a weekend warrior. The mains chargers cannot be programmed. Its just a way of having control.
@@SolarPowerChannelwithChris awesome. I'm glad you took my comments as constructive and not like I was trying to run you down. We all learn new things everyday. It's important we start our day looking for those lessons. God bless and keep em coming bud.
If your charger cannot be set for an appropriate lithium profile (the gel setting on many lead acid chargers is OK) a new charger is needed. The bms shouldn't be used to control the charge voltage, serious problems, even damage can be caused by doing this.
