It’s about 1 1/2 inches long and about 3/16 round. Wire coming out of end which goes to mppt. Nothing on top of battery to mount to . Need some way to fasten to flat top of metal battery case. Wonder if hot glue to top ? Any idea.
Keep the temp probe so you can monitor battery temps, just shut off the temp corrections IRT charging. it depends upon the type of cells you have older winston or calb types i would place it between the cells in the pack newer smooth calbs or the current EVE style batteries I would kapton tape it to the top in the center of the pack.
