DALY BMS firmware to assign board numbers (DalyBmsApp_20210216B.s19)

DALY BMS firmware to assign board numbers (DalyBmsApp_20210216B.s19) DalyBmsApp_20210216B.s19

DISCLAIMER: KNOW WHAT YOU DO! PLAYING WITH FIRMWARE CAN RENDER YOUR BMS USELESS. MAKE SURE; YOU DO NOT LOSE YOUR CONNECTION OR POWER DURING UPGRADE!

I wanted to control three 16S LiFePo4 BMS with one Monitor Software (well actually via a RaspberryPi). But all BMS "reacted" on the same address. After several emails to DALY support, I got this firmware.

I upgraded three BMS - one 60A and two 100A BMS. Two jumped back on right after upgrade, one had to be woken up by applying a charging voltage of 58V.

To assign individual board numbers, see ressource "DALY BMS Monitor to monitor 8 boards v1.2.5"

This firmware was successfully flashed onto the following DALY BMS:
  • 16S 48V 60A UART/RS485/CAN, code R16T-FK03
  • 16S 48V 100A UART/RS485/CAN, code R16A-FL15, R16A-FL26
If you flashed your BMS with this firmware as well, please add your BMS codes to this thread or send me a PN and I add your BMS types here.

Other successful flased BMS types:
  • 16S 48V 200A UART/RS485/CAN, code R32-01E (added 2021/3/14, thanks to marsal

ATTENTION!!! DO NOT TRY TO FLASH ANY BMS WITH CODE STARTING WITH R25!!!
DALY seems to have changed the hardware! I bricked a DALY SMART BMS by updating with the aforementioned firmware!!!
PLEASE CHECK YOUR BMS CODE! IT SEEMS THE CODE R25XX CAN NOT BE UPDATED USING THIS FIRMWARE!!!
The update started normally, but gave a fatal error stating something along the lines of "wrong firmware! abort immediately". But it was too late. The BMS seems still to work fine but I can not connect to it anymore. So it seems to have kept the initial setup (cell capacity etc.) but as I can not connect to it, it is now not much more than a Superior BMS ...

  1. DALY R25A-based BMS can be upgraded with this firmware

    I upgraded successfully two versions of R25A BMS (16S 48V 100A): R25A-GJS1 - this went without...

Thank you for the update. I have R25A1-GL18 (16S 48V 80A) BMS with ports Light Board/CANM/485/UART/BT. I am not yet brave enough to try the update.
Thanks for sharing! It's really hard to get anything directly from DALY. Also I appreciate the details and screenshots, they're very helpful.
