Customizable Battery Management System: Tiny BMS s516 (30A Peak Discharge)
Battery Management System (BMS) 30A – The Tiny BMS is an essential component for every Lithium battery. Enepaq Tiny BMS supports lithium batteries of any chemistry and up to 60 V nominal. Battery capacity from sub-1 Ah to 655 Ah can be managed easily. Tiny BMS measures individual voltages of parallel cell groups and manages the switching of load and charger. During charging, cells are balanced by bleeding off higher cells to accomplish full balance and maintain good health of the battery pack. State-of-Charge is calculated as well, and is available via communication bus to be displayed for the user.
Safe and Secure Battery Connection
For safe and reliable operation, it’s crucial to follow the correct sequence when connecting the Tiny BMS s516 to your battery pack. Improper connection can damage both the battery and the BMS. For detailed instructions, please refer to the Tiny BMS s516 manual on page 12, paragraph 2.3.2, Tiny BMS battery pack connection sequence. This section outlines the step-by-step process for safe battery pack connection.

- 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).
- Start Logging from Beginning: When enabled, this option will cause the BMS to start writing data at the beginning of the log file again when it reaches the maximum file size, effectively overwriting the oldest data.
- Start/Stop Logging: These buttons allow you to manually control the logging process. You can start logging data or stop it completely.

Ignition Feature (for high power 150A BMS only): This feature allows you to control the BMS based on an ignition signal, potentially from a vehicle. You can set the signal level for ignition on and off.
Precharge Feature (for high power 150A BMS only): This feature enables a pre-charge stage at a lower current before full connection to the load. You can choose to use either the internal FET or an external output pin for pre-charge control.
Charger Detection: This setting allows you to configure how the BMS detects a connected charger. You can choose between:
- Internal detection: The BMS uses its built-in circuitry to detect the charger.
- External input pin: The BMS relies on a signal on a designated pin to determine charger connection.
Speed Sensor Input (optional): This setting enables the BMS to calculate speed (likely for electric vehicles) based on a signal from a speed sensor.
Broadcast Protocol: This setting allows you to configure how the BMS transmits data to other devices. You can choose between:
