Having the LVD be temperature compensated so that the load is always
disconnected above the freeze point of the battery would be a Huge
Improvement on the whole concept of LVD. In combination with State of
Charge monitoring, like the Whiz bang Jr, would be the most effective,
and just program the disconnect to stay above freezing for a typical
lead acid battery. I got this from a Trojan White Paper:

FLA batteries will freeze easier if they are discharged. I suppose
that you could
use the battery temp sensor to make sure you charge them up good when
the temp gets cold enough.
