What is this thing?

I have 2008 Dynasty, There are Two wires from (Where) I don't know that are attached to a Small Back thing about as round as a pencil, 2 inches in length that are Taped to Side Of One Of My Coach batteries, Anyone know what it does?.

Possibly an in-line fuse? Tough to guess without a pic.

It's probably the battery temperature sensor. The other end of the wire probably attaches to the battery temperature connector on the inverter.

Glenn wins the prize. I have one that attaches to my inverter/charger and one that goes to my Solar Charger.

Second.. You have done a fairly good job of describing a temp sensor.

It's Not The Temp Sensor that Goes to inverter as that is a phone line & I found that line attached to post on (Coach) Batt, which I tested & found to be bad, So I need to splice New sensor to that line.
However The one I spoke of above has only Two Black wires as opposed to The Temp Sensor for Coach Batts as that has Green, Yellow, Black & Red wires.
But I Think Mike Hit it, I do have Solar panels & Just might explain the Two Wires attached to Starting Batts. I made error in My original post, These Two wires are actually taped to side of one of the Starting Batts not the Coach Batts..
Thanks Guys!
