I recently installed a SmartSolar MPPT controller in my camping trailer. As I replaced an older PWM contoller, I used the same mounting location which was inside the trailer under a bunk. The deep cycle battery is a sealed flooded lead acid battery stored in a marine battery box located inside a bin mounted to the trailer tongue. Given the difference in locations, I also installed a Smart Battery Sense monitor on the battery.
Does the Smart Battery Sense detect the battery temperature from the eyelet on the battery post or does it detect the temperature from being in contact with the plastic body of the battery? If the latter, does it matter where the Smart Battery Sense is mounted on the battery? Top? Long side? Short Side? Can I keep it just wedged between the batter and the box?
