Easy solar II.
Its Multi Plus II has an option to stop charging at certain low temp (with "internal temperature sensor"), and SmartSolar MPPT has its own low temp stop charging option (with internal temp sensor or Smart Battery sense).
So how does this work? If i have solar power, the SmartSolar MPPT charges the battery and determines low temp cutoff, BUT if i have shore or generator power for charging, MPII is charging the battery and its temp value is obeyed?
Confusing.
