BMV-712: low temp cutoff?

Hi All,

I've just ordered myself the BMV-712 to monitor a couple of basic 12v 100Ah lithium batteries. These batteries do not have any sort of low temperature cutoff protection. I was wondering if there was anyway to use the temp sensor for the BMV-712 to trip the relay when things get too cold? I only have a handful of nights a year where cold is an issue, so was hoping something like this would be enough to give my batteries some protection against low temp usage.

Normally it is ok do discharge your Li batteries at temps below 5c, with the understanding that they will deliver a reduced efficiency/capacity/discharge C rate.

You only need to prevent charging at below 5c temps. This is possible with VE smart networking.
