My Daly 300 didn’t let any “smoke out”, it just started getting weird. Its current readings were greatly exaggerated from reality. It was working in 2P 16S configuration 300Ah cells with a Heltec balancer monitored controlled to balanced over 3.4.
It ran flawlessly for about 9 months when I realized that the bms was disconnecting because of over current. When I looked at the app I saw the huge artificial load swings. I realized that I had made a mistake because my system was dependent on one bms instead of multiples. I could update the Daly and possibly brick it/no improvement or just replace it with two bms’s that also have active balancers which is what I did( loose the 2P setup). In the meantime I moved up the current setting to just above false tripping until the JK’s showed up. Presently I’m up to 5 JK’s (not all in same system). The only problem I had early on with the JK’s was state of charge but that’s figured out and another thread. The only thing that I haven’t figured out, is what to do with the sick Daly.
