    Daly 250A 4S BMS bluetooth connected but Smart BMS App shows no data

    I didn't try hard enough before asking the question here..... I reconnected the bluetooth module and it works again. Somehow the loose connection only affected the data pin but not the power pin. Case solved.

    Chargery BMS Cell Readings Inaccuracy. Should I be concerned?

    For the voltage issue you encountered, was it a BMS8T or BMS16T?

    Chargery BMS Cell Readings Inaccuracy. Should I be concerned?

    During the testing, I simply used an adjustable DC power supply to feed power to the BMS. I planned to use an old laptop PC power supply in the final setup.

    Chargery BMS Cell Readings Inaccuracy. Should I be concerned?

    I bought it directly from Jason last month and it came with the latest firmware. I used external power source for the BMS.

    Chargery BMS Cell Readings Inaccuracy. Should I be concerned?

    Just found this thread which discussed exactly the same problem I encountered that the 16s Chargery BMS gave inaccurate and unstable voltages (up/down for 30mV). It seems that Chargery BMS are good for the 8s model (with a lot of good comments in this forum) but not the case for the 16s model...

    DGJBD Bluetooth BMS - a short review

    I contacted the JBD manufacturer website in Alibaba and they replied that there is no option to have more than one UART/serial port. Does anyone have a JBD BMS (or the same but other other brand name) which has more than one UART/serial port. If yes, can you give me the link of the shop which...

    DGJBD Bluetooth BMS - a short review

    The BT interface is more convenient in checking the real time status of the cells. However, in order to record the data, I need to connect it to a PC or Raspberry Pi and in such situation I would like to have both interfaces working.

    DGJBD Bluetooth BMS - a short review

    Hi @pierre , thanks for the review. I am thinking of buying a JBD 100A BMS. It seems to me that the bluetooth module and the UART-USB interface are using the same 4-pin port so they can not be used at the same time. Is it the case?

    Daly BMS - Large Discharge Current Reading Errors

    Thanks a lot for sharing your experience. I did wonder what those items under the tab MCU-Calibration do and asked the Daly engineer whether those items can help in the calibration but the Daly engineer asked me not to touch them as they are not for users......even I kept pushing them for a...

    Daly BMS - Large Discharge Current Reading Errors

    Yes, I do. I followed the advice from Daly engineer to do the calibration but it didn't help. Glad to know that you may have a solution to this problem.

    New Daly "Smart" BMS w/ Communication. (80-250A)

    I did and I shared my experiences in a separated thread: https://diysolarforum.com/threads/daly-bms-large-discharge-current-reading-errors.19519/ As no one replies to to my thread yet...so I am not sure whether it is only a problem of my BMS or in general, amp readings of Daly BMS is really...

    Daly BMS - Large Discharge Current Reading Errors

    I am testing/trying the settings of my new Daly 4s 250A smart BMS. So far, I found that all those end/over/under voltage protection settings work. However, I found that the errors in the discharge current reading in the PC App (Sinwealth) are large. - No discharge current is displaced (when...
