    JK-B2A8S20P-H Bluetooth Application

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

    JBD 100A BMS no longer connecting to Android after LVD

    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...

    Xiaoxiang APK for JBD BMS unreliable

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

    JBD 100A BMS no longer connecting to Android after LVD

    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...

    Daly Smart BMS disconnect

    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...

    Daly Smart BMS disconnect

    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

    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...

    Daly 8S Smart BMS DL-BMS-R32-01E - unexplained shutdown a common problem?

    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...

    Daly 8S Smart BMS DL-BMS-R32-01E - unexplained shutdown a common problem?

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

    Daly 8S Smart BMS DL-BMS-R32-01E - unexplained shutdown a common problem?

    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...

    Is Daly 8s lifepo4 voltage configurable?

    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...

    Help needed with Lumiax MT3075 30A MPPT with Bluetooth - does the RS485 port work?

    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.

    Daly BMS not charging and phone apps awful

    "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.

    My Experience with a Daly Smart BMS / BT

    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...

    My Experience with a Daly Smart BMS / BT

    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.
