How to change battery identifier

[Zeezichtje]

I am using 6 EG4 Lifepower batteries. Everything worked till today. The battery identifiers are no longer unique. I assume because the remaining capacity of two batteries is exactly the same. The log suggests me to change the battery capacity. Could someone provide me instructions how to do so?

Please check that the batteries have unique identifiers.
SerialBattery:Change the battery capacities to be unique.

What I know is that on JK BMS you can change the capacity with the USB configurator to unique values, I have two 304 AH batteries but I set one to 303AH and the second to 304AH, that fixes this issue. Don't know if this applies to Lifepower batteries.
