I did set my Daly 4S 250 smart BMS to not charge below 5°C (not sure if it as of this value it will not charge or below this value).
It was now 4°C and I turned on the heating in the camper van.
After 1 hour the battery showed 12°C. I plugged in the camper van in the AC power socket but the battery refused to start charing. The charger did take over the load (running heater and lights). So the battery was delivering 0 watts, the 20W from heater and lights came from the charger.
It was strange; the BMS showed the low temp cut off error but at the same time showed 12°C as the temperature.
I changed to low temp cut off temp to 3°C via the app and the battery started to charge immediately.
Anyone knows if there is a delay for the low temp charging protection?
In the past weeks it the temp cut off for charging worked correctly. But there was a bigger delay always between the low temp and charging again at higher temp (like several days).
