Are there any advantages of temperature compensation versus simple low temperature cut-off for Lithium batteries?
I have a BlueSolar MPPT 100/50, 768Wh 12V Victron Lithium SuperPack and a BMV-702 + Temperature sensor. I could buy Smart Bluetooth dongles and have an "active" temperature compensation on the MPPT. But I'd rather avoid Bluetooth and use a VE.Direct non inverting remote on-off cable with BMV-702 relay to setup simple a low temperature cut-off of the MPPT charging.
The whole system will be stored outdoors in a small metal cabinet (close to Frankfurt, Germany). I expect temperatures from 0 deg C to maybe 50 deg C.
