There is a new firmware version available for 123\SmartBMS gen3: v3.2.2. This update contains small changes and a bugfix.
-Charge restart SoC can now be set to 100% in Normal Mode – this will keep the Charge relay on when the pack is full.
-Added a small hysteresis to Vmin and Vmax to prevent the relay toggling even when the cell voltage does not change.
-Fixed small bug in logging. When a cell over temperature occurs, the correct cell number is now displayed.
Please update the mobile app first. Then open the app, go to Settings and connect with your 123\SmartBMS. Tap on the “UPDATE” button under Firmware Version to update the firmware to the latest version.
