E8000 Different battery level display between battery and head unit

[Janluke]

Just recently I've been getting a different level between the battery and the head unit. They both start "full" but the head unit drops "blocks" quicker. I've not run the battery flay to see which one is correct. I do have different batteries and swap them around a wee bit. Any ideas?

This is the norm - I am overly simplifying it, but basically the head unit bases its calculations off data gathered during the ride you are on, whereas the bars on the battery just reflect the charge in it - you will often find if you stop, switch off the systems, and then switch it back on that the head unit is giving different readings.

That's great many thanks, I'd never noticed it before
