A new 123\SmartBMS gen3 firmware release candidate version is available: v3.3.11.
Note that this is not an official release yet, you can try out the firmware to test the new feature(s).
Changes in v3.3.11:
-Added status byte 2 to the UART protocol
-Added setting Vfull – When all cells are above Vfull and Sync SoC below current x setting, the SoC is synced to 100%. Vfull now can be set independent on the Vbalance. This can be handy for example when you see your system does not reach Vbalance completely, or when you do not want to use the BMS’ passive balancing but instead will use an external balancer.
For the complete list of new features in firmware v3.3, see this post.
All changes for v3.3
The firmware contains the following changes from v3.3.0:
Changes in v3.3.11
-Added status byte 2 to the UART protocol
-Added setting Vfull
Changes in v3.3.10
-Fix “Charge/discharge restart delay > 255” bug where values higher than 255 did not work correctly
Changes in v3.3.9
-Fix “Charge/discharge stop delay set to 2 seconds” bug where a value of 2 seconds did not work properly.
Changes in v3.3.8
-“Clear energy counters” now also resets the battery capacity measurements to “Pending measurement”.
Changes in v3.3.7
-Sync all key-value pair data in UART protocol to ensure transmitted multi-byte data cannot change during transmission.
Changes in v3.3.6
-Added new key-value pairs to UART protocol which contain extra info like SoH, charge cycles, firmware version etc.
Changes in v3.3.5
-Decreased temperature threshold hysteresis from 4 to 2 °C.
Changes in v3.3.4
-Fixed voltage based SoC correction bug
Changes in v3.3.3
-Added configurable “Sync SoC to full below charge rate %” setting
Changes in v3.3.2
-Fixed voltage based SoC correction bug
Changes in v3.3.1
-Added daily and total battery charged & discharged battery energy (kWh) counters
