A new 123\SmartBMS gen3 release candidate firmware is available. This update contains an extra Expert Mode setting: “sync SoC to full below charge rate %”. Previously, this parameter was fixed to 5%. When all cell voltages are above Vbalance and the charge current rate was below 5%, the SoC would sync to 100%.
This upper threshold is now configurable, which is needed for example when a charger cuts off charging when the current is below 7% (still above 5%).
For all new features in v3.3, see 123\SmartBMS gen3 release candidate firmware: v3.3
