I agree, the fault reporting of this Daly BMS is fairly poor. I equate it to a check engine light in a car that goes away once you turn car off. 🙂

Re: 3month old Extreme team 100ah,48v bms failure?
I no longer use or recommend Daly BMS’s. Having said that, the couple I did try definitely reported fault conditions correctly, hence my comment about faulty custom firmware in there.
It’s not really a POS, it does its job correctly, can handle massive currents but my two problems with it are its cell balancing limitations and its inaccurate coulomb counting, otherwise I don’t mind them. |

Re: 3month old Extreme team 100ah,48v bms failure?
Pat, Is there a way to reset the bms via the app when it is tripped? That would be better than pushing cart home and plugging it in when (if) it happens again. I am bummed because I am scared to use the cart Incase it flips out and trips for no reason again.

Re: 3month old Extreme team 100ah,48v bms failure?
Daly BMS’s normally reset themselves when the fault condition is removed. There’s normally no need to plug into a charger.
Having said that, the normal way of waking up a BMS that doesn’t start itself up is to apply a slightly larger voltage to the BMS charge port than is on the battery. That’s what plugging a charger in does. I haven’t tried this but next time it trips you might try connecting a 1.5v battery across the B- and C- ports on the BMS. Any small battery will do (AA, C, D etc.). Place the positive on B- and the negative on C-. That should wake it up. If it doesn’t work then you may need more than 1.5v so try 2 batteries in series to give 3v. Let me know how you go please. |

Have you tried increasing the sleep time like I suggested in post#4 of this thread?
