smallBMS low temp charger disconnect

The data sheet and manual for the smallBMS state that the charge disconnect output “becomes free floating in case of imminent cell over voltage or over temperature”. No mention is made of under temperature. Is it safe to assume this is an oversight in the data sheet and manual, and that the charge disconnect output does indeed activate upon under temperature, as well as over temperature?

Hi @pcg,

The Charge disconnect output becomes free floating also at low temperature <5°C. It is mentioned in the General description at LED indicators. There will soon be an update to both the manual and datasheet that will make this more clear. Thanks.
