Battery Voltage Cut-Off Start

Battery Voltage Cut-Off Start determines the voltage at which the controller begins reducing available motor current.

As battery voltage falls below this point, power is gradually reduced. This helps protect the battery while still allowing the vehicle or machine to continue operating.

Higher values provide additional battery protection, while lower values allow more of the battery’s capacity to be used.

Example

For a 22S lithium-ion battery, a common setting is 74.8V (22 × 3.4V).

When the battery voltage falls below 74.8V, the controller will begin reducing available motor power.

In simple terms: this is where the controller starts limiting performance as the battery becomes depleted.
