  • Post in thread: Daly smart BMS

    I was just given a driver from the supplier and to great success. Sorry for the pictures, I love documenting in case some people need help down the track. Now on COM4 What settings am I to be adjusting? Selecting the MCU window, and reading the instructions, it says the 'Design...
  • Post in thread: Daly internal settings

    hi we are looking for settings for the daly BMS app. your answer does not apply to the questions the first sentence: "I have a Daly bms, but the manuals don’t explain the settings and exactly what they do / affect" if anyone can assist it will be a great aid. I am surprised that despite the...
  • Post in thread: Charging with benchtop in series

    Just realised I didnt have the psu connected to the P- of the BMS! fixed image
  • Post in thread: Top balancing taking forever

    Great news all. I arrived home at 2:40am to find the PSU was at 3.5V and the amps reading 0AMPS Unplugged the terminals from the battery and the battery read 3.508V!! Woohoo. I'm going to update my opening post with the solution once I successfully charge the 4 batteries together in parallel...
  • Post in thread: Problem with the DC power supply for top balancing

    I can confirm that if you are using the cables from the psu, I had the exact same problem. Creating my own connectors solved the problem marvelously

    Bump. Also need help with this

    Love your dc fuse box setup!
  • Post in thread: Renogy charge controller jumps up to 14V then down to 12V randomly with warning flash

    Inverter is connected to the battery. Ive just tested turning on the inverter at the same time. The Inverter does not shutdown when this happens.
  • Post in thread: BMS/Inverter turns off after pushing 10A

    WOOPS YOURE ABSOLUTEY RIGHT its 8.8mV on the battery positive to inverter positive I am super sorry, haven't gotten used to this clamp meter compared to my usual one
  • Post in thread: Daly smart BMS

    Wow, that sucks I already ordered 22AWG based on that. However, I heard a trick is to fold the exposed wire over itself and crimp. I purchased a wire gauge measuring tool so will confirm for you all the exact size once it arrives.
  • Post in thread: Top balancing taking forever

    Thnanks for your input Hedges. Ok, unplugged, I reset the PSU to 3.6V, turned it off, connected the terminals and switched the PSU back on. PSU Currently reading 3.61-3.62V Roughly 8 Amps.
  • Post in thread: Daly smart BMS

    Ok, I am plugging this cable into the monitor port of the BMS so it seems I am doing everything correct. I launch 'BMS Tool' and receive this popup, which has been translated by the Alibaba Supplier. "It says, sorry, no available port is detected in the current computer, please insert the...
  • Post in thread: DIY copper bus bar mounted on wood

    Based on the measurements, the busbars are 1/8” x 1”. Using the ampacity chart, the maximum amps able to be run is 270A. The maximum draw of my system will not exceed 200A (inverter wont exceed 160A and the bms is 200A)
  • Post in thread: Very minor difference in busbar size between lifepo4 cells

    I had to create 3x busbars with a different thickness to the ones that came with my EVE lifepo4 cells. The main reason was to successfully connect one pair of the parallel cells in series successfully as illustrated in the photos. The new busbars are 1/8" thick, unsure of the size of the...
  • Post in thread: Charging with benchtop in series

    The only setting that I have that reads 3.4V is the balanced open start volt. Photos attached. Any clues? I think I have seen the charge MOS thrning on and off in the app
  • Post in thread: Charging with benchtop in series

    Yep chg MOS light in app going green and grey
  • Post in thread: Renogy charge controller jumps up to 14V then down to 12V randomly with warning flash

    Yes. This was set up when I first got them about two years ago.
  • Post in thread: Why isnt my benchtop charging my batteries?

    13.45V WHOLE PACK 3.36V,3.35V,3.36V and 3.36V voltage of psu is same as the displays
  • Post in thread: Cells read 14V but BMS negative reads 10V

    Hey guys! Very excited to finally wire all my batteries up. Using a Daly "Smart" BMS I have 4 cells wires in series @ 280aH or so. Cell 1 negative to the positive after the fuse reads 14V DC However, on the BMS P- to positive of the fuse, I am reading 10.28VDC Any ideas why this is? I've only...

  • Post in thread: Cells read 14V but BMS negative reads 10V

    Okay, I launched BMS tool on windows 10 and suddenly it changed to to 14VDC Can anyone tell me why the SOC is reading 0% in the software? How should I setup the software? I havent calibrated anything yet.
  • Post in thread: BMS/Inverter turns off after pushing 10A

    I've tightened the nuts far more than they were before using a mini wrench with your instructions. I am using grub screws I think they are called with a nut on the top . I am still very anxious to try tighten them any further as I have no measure of how tight they can go before I damage them...
  • Post in thread: Lug size for teeny tiny BMS wires

    I checked the size of the wires with a wire gauge I ordered. The wires fit 22AWG-23AWG. Those terminals are marked for 0.75 - 1.5mm2 = 19 - 16 AWG. Im still out of luck. I ordered some terminals from element14, but I got the stud size wrong as they need to be M6
  • Post in thread: Cells read 14V but BMS negative reads 10V

    Had to hit the Scan All button on the Info page. Lonely thread but I'm sure it will help someone one day!! Am I okay to connect this to my inverter or should I change some settings? Info page System Charge Discharge
  • Post in thread: Daly smart BMS

    Glad I could help. Honest made my day when I first read this. Ive wired my cells in series and connected via bluetooth. What does the greyed out “balance” icon indicate in this photo? I want to make sure my settings are correct before I apply a load via the inverter
  • Post in thread: Wire size and fuse size for inverter conflicting information?

    What am I to do with this?
  • Post in thread: Cells read 14V but BMS negative reads 10V

    Is there a battery voltage setting ? where is that? I have 4s 12V which would be 3650mV * 4 = 14,600mV I adjusted the under and over voltage as per suggestion. What about the Under voltage release?
  • Post in thread: Very minor difference in busbar size between lifepo4 cells

    **** YES MAN! (ecstatic as it will save time and not have to redo so many!)
  • Post in thread: Renogy charge controller jumps up to 14V then down to 12V randomly with warning flash

    They are in range. I measured all of the cells and they are just above 3.3V. I can charge my battery with a benchtop power supply perfectly fine without this happening, so let me know what you think.
  • Post in thread: Cells read 14V but BMS negative reads 10V

    Cool, I adjusted to suit this. How do the pictures below look? I adjusted as per your instructions. Could you double check the temperature release settings on discharge and charge are okay? I don't really understand what this means.
