Re: Extreme Team issues - post here
Is this balance control setting applicable (even for passive balance without an accessory) ?
I haven’t used a Daly. |

I doubt they’re pouch cells, most likely prismatic with solder tabs as pictured below. BF406C33-FCD1-46E8-98E8-F58B1D6516E2.jpeg |

However, I was in an accident Labor Day weekend and did not use my cart several months while recovering. When I got back to it, I charged the battery and let it top off all the cells. Rode the cart several days with no issues. But, I noticed I couldn't get the bluetooth feature to connect to my smart BMS app on my phone. When I took the lid off my battery to push the "find" button on the bluetooth module (never had to do this before) it would connect to my app on my phone, but won't stay connected long, and it was saying cells 3 and 23 were 0.0 v, but I know they aren't becasue by battery is still getting to 87.6v full charge right after I unplug the charger. I also noticed many of the settings appear to be reset. For example, the high cell voltage was set to 0.0 and the balance board settings only show 6 cells on the first harness and 6 on the second. I unplugged the balance wire harnesses and I'm getting the proper voltages at all the pins. Now, after plugging everything back in, it appears the BMS keeps cycling on and off and the bluetooth won't stay connected. While trying to restore all of my settings, the bluetooth will disconnect and when I go back into the app, they are reset again. Also, the voltage at the main lugs on the battery, that connect to the cart, keep changing. It's like the BMS keeps resetting becasue it will read around 81 volts and then while holding my multimeter on it, they will slowly go down to no voltage. I also noticed when I opened the lid that the fan was cutting on and off randomly on the BMS. Does this sound like a bad BMS? or, is there a way to do a hard reset on it or firmware update? Thanks, |

Re: Extreme Team issues - post here
Remind me which BMS you have again please, Daly?
Certainly seems like your BMS is faulty. At this point I wouldn’t trust what the BMS is telling you and the readings of 0 are probably missed communication messages. Writing new data to the BMS is probably fruitless as well. Have you tried resetting the BMS by removing all power and reconnecting? This can be done by removing the cell connection plugs. Check each cell to confirm their voltage report back. Next steps are dependent on the condition of your cells. |

Re: Extreme Team issues - post here
Pat,
Yes, I have the Daly 500a with fan. I let the BMS sit all night and day today with the B- from the pack disconnected, the balance harnesses unplugged and the BT module unplugged. Checked every pin on the balance harnesses and they all show around 3.3v. Connected the B-, BT and balance harnesses to restart the connection process and it’s still doing the same thing. Will connect to BT on the smart BMS app and let me start changing settings but then drops the connection and all the settings go back to where they were, which are grossly incorrect. I’ve ordered a JK 24s 200a BMS to replace it. That being said, what’s the best app to use in setting up the JK parameters and monitoring cells? |

Re: Extreme Team issues - post here
I'm glad the BMS didn't take any cells out with it. Faulty Daly's have been known to do that.
Excellent BMS choice there. JK has its own app, which is very good. You'll find it has many more parameters than the Daly, a good thing. Yell out if you need any help setting it up. |
