It needs location access to get Bluetooth-LE access. So all apps should ask you for permission.

Thank you for the suggestion. Yes, a few times in the process. BT comes back but same result. I also like to mention since I obviously got a bunch of devices around that I turn off BT on any of the phones I do not use at the moment, only using a single phone at a time to avoid interference...

Did the new BT module resolve the issue? I have connection issues with every app I tested, used to work fine.

I build a 8S LifePo4 battery with a JBD 100A BMS for a cabin and used it for maybe 2 years but 3 months ago vacated the cabin, sold the solar setup to the new owner. The BMS was always working fine for 2 year with the initial firmware and either Xiaoxiang or Carplounge connected fine. I got a...

My BMS got worse over time. It had a few more unexplained outages when the BMS just did not respond to anything anymore. Could not wake it up via USB either. Unplugging and reconnecting it got it back up and it worked again for a week or 10 days, After that same issue. V Now it seems...

Mine also shut down a few times with the BMS locking up. You cant start it via USB. Look for this thread here: Daly 8S Smart BMS DL-BMS-R32-01E - unexplained shutdown a common problem

I exchanged a few emails with Daly but that seems to be a waste of time. I send more details and log files but didn't get anywhere with them. I had 3 more shutdowns while the system basically was at idle. When we are not at the cabin only the DC DC 12V converter is running to supply the DSL...

Sleep: Yes I did that within the first 2 days and had no issue after that. I think the sleep function only affects BT, the USB UART should have worked regardless. Support: I did email them but I am not very optimistic about it. Obviously I want to hear either "use this firmware" or "new...

I think the Daly is potted inside the pretty red enclosure and has no meaningful way to be disassembled.

I use the 8S Daly Smart BMS DL-BMS-R32-01E with a 24V 100Ah LifePo4 setup. This mostly works OK. I did set up the system just over 3 months ago so I have about 100 days experience with it. The current measurement seems off, with a 1KW resistive load on the inverter the BMS meter jumps around...

I have the 8S Daly Smart BMS and I can adjust the values. This can be done via Bluetooth or USB cable using the the PC software. When I ordered my unit the vendor told me the both the 3.65 and 4.20 units are identical and just preconfigured with different thresholds. You need to adjust 4...

No, I did not. I believe found the pin-out at some point but never actually made a cable. We recently moved to a tiny farm house so I probably can’t locate the diagram but if I stumble across it I let you know.

"Switch alligator clip from P- to B- and it works but doesn’t show readings" is to be expected. The current would not flow through the BMS if you hook it to B- so the BMS will not see the charge nor be able to control it.

Bluetooth is not yet active if it only says "Device name". You can apply a charge voltage or start it with the light board. You can also hook up a momentary switch to the proper pins to get it started. After it starts working you can increase the timeout value to "65535s" keep the Bluetooth...

If equipped with the ports than you can see the white connectors. No need to remove anything. My Daly Smart BMS just looks like the diagram sheet you have. You may have received a different or incorrect model.

I went to a residence with a large yard full of panels. Yes, a few text messages to set up an appointment was all that was needed.

Tank: warm up the water when energy is available i.e. when your batteries are full make hot water. Heating the van for freeze protection? Just heat the tank with a 12V silicone pad, 120W or so to 45F and all is good. I successfully used a pad recycled from my stock driver seat. It is about...

I am using the 100A Smart BMS with PC software BMSmonitor V1.2.8 which seems to be an improvement over previous versions. Does this software allow me to set the scale of the gauge either in an INI file or otherwise? My system uses between 0-50A max so I like to set the scale to 30V max and...

I bought 4 used 250W panels from them and the performance was not as I was told - was actually like new. Under promised, over delivered, low cost and he gave me a hand with loading them. Awesome.

Mass and insulation are the key. Paraffin probably works as well as oil or water until it becomes solid. I would assume heating up 1000 pounds of oil/water by 100 degrees would store about as much energy than 1000 pounds of paraffin. Water is obviously cheaper and non flammable but oil could...

Make sure both are at the same state of charge, low state preferred. When you connect them a potentially high current will flow from the higher charged battery to the lower battery. You can mitigate that with a low value resistor, a 100W car halogen bulb or low state of charge. If you use a...

Our off-grid farm house runs of 24V LifePo4, 1000W used panels and 2 inverters, 40A MPPT. All continuous loads are on 24V except the DSL modem that is on a step down power supply for 12V. You can find decent 24V LED ceiling lights as well. Our fridges run off 24V, the larger one as a fridge...

Or a diode or 2. Each drops the voltage by .7 so if you charge to 4.02/cell we would end up at 16.08V minus one diode .7V = 15.38V which many inverters support. 2 diodes in series would drop it another 0.7V and almost any inverter should work. Not sure if I have enough head room to convert the...

I build from left over batteries a 12V battery box, 4S21P and put a meter on it, some USB charging ports and cigarette lighter plug for a fridge or something. I would like to use a cheap 150W-300W inverter but all I found where rated to 15V input max. Any recommendations for a cheap brick...

I bought this device on Amazon branded as "PowMr 30A MPPT Charge Controller" and it seems to work well. I am thinking to hook up the RS485 port but neither the Amazon vendor nor manufacturer did respond to my inquiry about pin-out and software. Did anyone try this device yet and did you get...

Yes for lead acid type systems voltage based works, i would not call it precise but a good guess. Since the voltage drops as the SOC goes down the controller can display an approximation. That doesn’t work with lithium cells as those have about the same voltage over most of the SOC range. A...

I am still in the 30 day money back period. After the 30 days are up and I am still happy with the battery we will do some battery surgery. I am curious about the BMS as well as the cells used and also like to solder some AWG 10 copper cables to the BMS. Since this will be somewhat invasive...

Tested low voltage protection of the BMS since the SOC was at the 2% range anyway. So it took just a few minutes to complete. Setup used: 6A load on Anderson connector, volt meter on NEMA C13 connector. Showed 12.3V at start of test, drained it to 10V quickly and the build-in BMS shut down...

The line "50 amp breaker is tripped and will not reset " points to some wiring issue. To check start with taking it apart to look for an error in your setup. Make sure you keep some charge in your battery at all times, Lithium or LA needs to have some capacity left or either dies a premature...

I did use the battery for a week and decided today to run a load test. I did charge the pack with the provided charger until the charger cut off. Discharge load for my test was between 8Amp and 13Amp continues. At the end of the test the low voltage protection cut the battery load due to "Low...

The MPPT controller max current is rated for the battery end so 600W / 12V = 50 Amp assuming everything reaches peak. So I still think this isn’t right unless your controller can protect itself should an overload ever occur. Basically if you use a single 17.8V 5.6A panel which is 100W and the...

Since you use series panels I assume you use an MPPT controller. A PWM controller isn't suitable for this setup. The rest is a 2 part answer but this is how it goes.... First part depends on the panels and the MPPT maximum input voltage. Please check your panels open voltage, multiply by 3...

I assume the protect feature is the Victron module that is wired to disconnect the battery from the inverter after a certain low battery voltage (say 11V) is detected. Now the Battleborn manual says this: Low voltage: < 10V If an individual cell falls below a prescribed threshold during...

Agree with MrNatural, since the actual equilization is disabled it doesn't matter what voltage is set. Likely the software guys set a an allowed range from X to Y and you just can't set anything outside that range. You should be OK as is.

Doesn't all current in and out of the battery passes via the controller? I understand the limitations about losses and an approximate SOC is fine. The Rich Solar controller I have was set using the PC software to know about my battery. I set the capacity to 60Ah, so it should be able to...
