Can not enter temperature compensation to BSC IP65 12/5 Charger

I have victron agm deep cycle 220Ah battery and BSC IP65 12/5 charger with most recent fw.

For some reason, when I enter to Victron Connect via my iphone, and try to set the temperature compensation for my vattery (expert settings) it has already the default -16,mV/C but it is shown on red and I cannot save/click OK button if value is negative. Positive values are accepted but when I click OK it resets as 0 / no compensation. Where is the problem?


Under battery preset “user defined”.
Try enabling temperature compensation.

Nope, it just disables it if I set anything to this parameter. Negatives not accepted and 0 or positive turna conpensation disabled

It has no temperature sensor to connect to the battery, how should it be able to compensate ?

The field in victroconnect demo is grayed out.

Manual says there is internal temperature as it should ve to such function to be avle to work. Also, it is not initially grayed put, only vecause if zero or positive value entered, it will disable the function. Also, it wont let save negative value.

I found it in the manual…

Did you set the battery type to user defined ?

Yup. Everything has been tested, just cannot enter negative value there. Default -16mv works fine if I dont alter it any way.

What if you just decrease from -16 to -32 ?

It wont let me click OK if there is any negative number and any positive number will result compensation disabled.

Tested with another devixe, basic mppt solar charger. Similar thing with negatives, but any positive can be saved, but it should NOT ve positive. Is it with victron connect problem, or my iphone regional settings etc?


What connect version are you using ?

I have 6.16

Yes the newest one versions for all… and seems like it is problem with all devixes, could it ve country specific …
