Installing the Inverter/Charger

Step 5: Connecting the Battery Temperature Sensor (BTS)

Installing a battery temperature sensor (BTS) extends the life of a battery by preventing overcharging in warm temperatures and undercharging in cold temperatures. With a BTS monitoring the battery temperature, the voltage delivered to the battery is adjusted according to the battery’s actual temperature.

The BTS has a self-adhesive backing and attaches to the side of the battery. A 25-foot (7.6 m) cable is supplied with the BTS, as shown below.

Mounting Options

You can mount the BTS in one of two ways:

•Mounting the sensor to the negative battery post allows the internal battery temperature to be sensed and provides the most accurate results.

•Attaching the sensor to the side of the battery using the self-adhesive backing also provides good results in most situations.
