Minimum Input Voltage

The Minimum Input Voltage setting determines the lowest voltage the controller will allow before shutting down.

This acts as a final layer of protection against excessive battery discharge and prevents the controller from attempting to operate when the supply voltage becomes too low.

⚠️ This value should be selected based on the battery chemistry, cell count and controller datasheet.

⚠️ Setting the Minimum Input Voltage too low can result in battery damage due to over-discharge.

Example

For a 22S lithium-ion battery, a Minimum Input Voltage of 55V provides a final safety limit. If battery voltage falls below 55V, the controller will stop operating to protect the system.

In simple terms: this is the controller’s emergency low-voltage shutdown point.
