It's a calibration setting.

It determines the final voltage per cell when using a balancer.

Default should be ZERO.

You increase setting if you made a custom longer cable or added a balancing board in order to make up for the added resistance. This is indicated by a cell not being charged to its max limit such as 4.2 for LiPo.

You decrease if any one cell is taking a greater charge than it should. (Beginning of a bad cell and or puffing )

*This setting should be per memory allocation for ONE specific battery.

So if you decide to change this setting and have two of the same batteries and using one memory bank, the change will correct the difference for one batt and can negatively affect the other battery.

A decent digital voltmeter is essential to assure charger is not off and or needs calibration or service .

Lithium Ion 18650 cells for example do not all charge to the same voltage by design. This allows you to charge to say 4.35 volts per cell as sometimes recommended in the spec. sheet. Use with caution and only if you know what you are doing.
