JBD App - Cell "fullness" meter

[Simi 60]

Hi and a happy new year to all
We are finallyr readyfor installation of our 3 X 24v eve 280 house bank

A question, looking at the pic, if the batts are fully charged shouldn't the cell bars be showing more full, like my scribbled first bar and the bright green like in to 100% semi circle?

As I click between menu pages I see for a fraction of a second full bright green with same v but then it reverts to half full yellow as shown.

Can't figure out if this is how it should be and if it can be changed

No.

LFP cell voltages settle after full charge. You're likely fully charging at 3.55-3.65V/cell, so there needs to be some room to the right to accommodate the higher voltages.

 

[Simi 60]

Agreed, but even at 3.55 it hasn't gone past the half way line

Software also accommodates Li-ion that goes up to 4.2V.

Fair enough, just looks a bit odd and I have been asked why the bars aren't full and green vs 50% and an unhealthy puss colour ?

As long as it's doing its thing and "normal" I am good.
Thanks

I'm pretty sure the app was originally intended for Lithium Polymer cells, which are higher voltage. There are versions of the app that look more fully charged at 3.4V, but the later version (which also seems to work better) doesn't show graphically how full the cells are. You just need to learn to ignore it.
