Fogstar app

[BusyBuilder]

I've charged my batteries up on ehu after installing a second battery.

The Fogstar app on voltage page shows, 13.5v, 4 cells which show 3.385v each, only the top two show temperature , 15.7c and 14.3c, and 3 cells are orange and 1 blue.
now my eyesight is not good enough to read these small coloured bits, so could someone explain please.

I have said i'm fitting a shunt but not got it yet.

I rarely ever look at the app but from memory blue is the lowest cell voltage and orange the highest.
As all cell are reading the same voltage nothing to worry about. It will also tell you what the cell variation is.

only the top two show temperature , 15.7c and 14.3c,

Temperature is not per cell. There is only 2 temp probes per pack, placed in 2 different locations, one may be higher near a terminal or midd cells. The bms will work with the highest reading for high voltage protection, and lowest reading for low voltage protection.

and 3 cells are orange and 1 blue.

When all colours match, all cells have same voltage. Different colour points to different voltage, even 0.001V and is dynamic as you charge-discharge, voltage will change.
Nothing to worry about, unless the diference is upwards on 0.05V , 50mV.

In the new app temperature reading seem haywire mine is showing 14°C but in advanced its showing 112 to 312°C
