Battery Voltage Regen Cut-Off End

Battery Voltage Regen Cut-Off End determines the voltage at which regenerative braking is completely disabled.

Once this voltage is reached, no additional energy will be sent back into the battery.

⚠️ This value should always remain below the Maximum Input Voltage setting and within the battery manufacturer’s specified charging limits.

Improper regen cut-off settings can result in overvoltage faults or damage to the battery and controller.

Example

For a 22S lithium-ion battery, a common Regen Cut-Off End setting is 92V.

When battery voltage reaches 92V, regenerative braking will be completely disabled to prevent the battery voltage from exceeding its safe charging range.

In simple terms: this is the voltage where regenerative braking is fully turned off to prevent overcharging the battery.
