- Cell Settings: The Battery Insider software allows for comprehensive configuration of various cell parameters within the Tiny BMS s516.
- Voltage Cutoff Thresholds: Users can set critical voltage thresholds to prevent over-charging and over-discharging of the battery pack. The software enforces a hierarchy where the Fully Charged Voltage must be within the range of Over-Voltage Cutoff and Fully Discharged Voltage, and the Fully Discharged Voltage must be within the range of Fully Charged Voltage and Under-Voltage Cutoff.
- Charge Finished Current: This setting determines the minimum current at which the BMS considers charging to be complete. Different BMS models and configurations may have limitations on this value.
- Balancing Threshold and Allowed Disbalance: These settings control the automatic cell balancing behavior within the BMS. Cell balancing helps to maintain equal voltages across all cells in the battery pack, thereby extending its lifespan.
- Number of Series Cells: This setting allows the user to configure the BMS for the specific number of series-connected cells within the battery pack.
- Battery Capacity: The user can specify the total capacity (Ah) of the battery pack.
- State-of-Charge (SoC): The Battery Insider software allows for manually setting the estimated remaining capacity of the battery pack.
- Upload to BMS: This button commits all configuration changes from the Battery Insider software to the BMS hardware.
- Safety Settings: The Battery Insider software allows configuration of various safety parameters within the Tiny BMS s516 to protect the battery pack from damage:
- Over-voltage and Under-voltage Cutoff: These settings define the voltage thresholds at which the BMS will automatically disconnect the battery to prevent over-charging or over-discharging.
- Discharge and Charge Over-current Cutoff: These settings define the current thresholds at which the BMS will cut off discharge or charging current to prevent excessive current flow. The allowable current limits depend on the specific BMS model, configuration, and current sensor used.
- Over-temperature Cutoff: The BMS can shut down if the battery pack temperature exceeds the user-defined maximum threshold.
- Low-Temperature Charger Cutoff: The BMS can prevent charging if the battery pack temperature falls below the user-defined minimum threshold.

Data Logging: This feature allows you to record BMS data over time for later analysis.
- Data Selection: You can choose which specific BMS data points to include in the log file. The image doesn’t show the available data points, but it likely includes parameters like cell voltages, currents, temperatures, and battery pack voltage/current.
- Logging Interval: This setting determines the frequency at which BMS data is recorded in the log file. It can range from 1 second to 1 hour (3600 seconds).
- Log File Size: This setting defines the maximum size of the log file. The BMS can automatically start a new log file when the current file reaches this size limit. The allowed range is from 2 MB to 1024 MB (1 GB).
