Battery Voltage Regen Cut-Off Start

Battery Voltage Regen Cut-Off Start determines the voltage at which regenerative braking begins to be reduced.

As the battery approaches full charge, the controller gradually limits regenerative current to prevent the battery voltage from rising too high.

This setting is particularly important on systems with strong regenerative braking.

Example

For a 22S lithium-ion battery with a fully charged voltage of 92.4V, a common Regen Cut-Off Start setting is 90V.

As battery voltage approaches 90V, regenerative braking current will begin to be reduced.

In simple terms: this is where the controller starts reducing regenerative braking to protect a nearly full battery.
