The most important balancing stat in our experience is the accumulated mAh. For example, if all cells but one are balancing a lot, that means that cell has some self discharge. If it gets bad enough that you struggle to balance in a day, it should be replaced.
Keep in mind that it resets for each cell the first time it balances in a day, i.e. values from the last time a cell balanced will persist even if other cells balance.
This stat can be found in Telemetry > Cell Info alongside the data attached with the last measurement.
We have also been hard at work at better charting and representations on the web, and will be ready to show it off soon:
Thanks @james! I’ve been looking into the Telemetry>Cell Info screen and already wondered why I have one cell [57] that never enters Bypass. Also clueless what RepeatC means.
