    Daly 250A, current (amperage) reading jumping/inaccurate/inconsistent

    What did you end up doing with that bricked BMS? I could use it for parts and would be willing to pay you for it!

    I see on one side 3 connectors where one is for the NTC, the middle is for the UART, and the other one is a five pin marked with pins Agnd, a, and B. The back connector is for the cell connections. The other side has three connectors labeled: 2 pin Key and GND, 3 pin TX, RX and GND, and 2 pin...

    I have a Daly 4S 100 Amp smart BMS and would like to get the datasheet for the sh39f003 and also a copy of the firmware for this BMS. Where does the ISP connect to? Do you have a schematic for this BMS? Thank you for any info you could provide.

    EPEVER Aggervation AN6415

    I am having the same problem but with an Epever XTR 4215N. I have a shunt inline which was calibrated when doing full discharge and full charge battery testing. The shunt is telling me that the batteries are 85% charged but the Epever 4215N is saying 97% charged. This morning it started out at...

    JBD BMS Wi-Fi Module

    Do you have the windows version of the source? Also, do you know how I can get the firmware source for the JBD 4s 12 v 120a and 8s 24v 100a and 16s 48v 100a BMS? The reason for asking is that I am in the process of designing a 300 amp 4s 12 v and a 8s 24 v and a 16s 48v LiFePO4 (280 Ah cells)...

    Welcome to the club. This is ridiculous. Looks like if the problem is too hard they just ignore you.

    Overkill Solar vs JBD direct purchase

    Mike, Yes, I did purchase with a credit card but I need the BMS. The problem is he not only marked the BMS with the wrong label but he sent me a BMS for Li Ion batteries. Lucky I hooked up the PC app and saw that or I would have blown up $1400 worth of LiFePO4 280 Ah batteries which I waited...

    I am having the same problem with support for an 8s 100A LiFePO4 BMS. It seems the BMS they sent to me from OKS is for Li Ion and I am asking for the .fig file for LiFePO4 but no answer. Initially I got a response from Steve with regard to an apparent mislabel of the product. My 8s 100A BMS was...
