Battery Temperature
For use with solar
charge controller
Model No.:
1. Battery Temperature Sensor Model No. DC-BTS-A-C (Fig 1) is designed for use with Samlex Solar Charge Controller Model No. SCC-30AB. It senses the
temperature of the battery installation and sends this information to the
Charge Controller, which automatically adjusts its voltage to ensure proper
battery charging depending on the ambient temperature of the battery
Fig.1 Components of Battery Temperature Sensor
1. Ring terminal with embedded sensor
2. Bare Positive (+) end (Red wire)
3. Bare Negative (-) end (Black wire with red stripe)
4. 10 Meters of two wire color coded cable
• Positive wire - Red
• Negative wire - Black with red stripe
2. It consists of a sensing element that is embedded in the ring terminal
• (1, Fig 1). This sensor is attached to 10 meters of two wire, color coded
cable (4, Fig 1). The cable is polarized i.e. red wire has Positive polarity
and the black wire with red stripe has Negative polarity. The other ends
of the wires
(2, 3, Fig 1) are bare and are required to be connected to the terminals
on the charge controller marked BTS+ and BTS– (Fig 2).
3. Detailed operation of the Battery Temperature Sensor is further explained in
the Owner’s manual for the Charge Controller Model No.SCC-30AB
Note: Voltages shown below are for 12V battery.
For 24V battery, multiply these voltages by 2.
Connect the wires of the Temperature Sensor here.

4. This ring terminal should be mounted on a terminal post of a battery in
a bank.
• Switch off all devices operating from the battery
• Route the sensor cable to the charge controller
• Connect the Positive (+) bare end of the wire (2, Fig 1) to the Positive
terminal marked BTS + on the Charge Controller (Fig 2)
• Connect the Negative (-) bare end of the wire (3, Fig. 1) to the Negative
terminal marked BTS – on the Charge Controller
Connect the ring terminal of the sensor (1, Fig 1) directly to the Negative battery stud. This provides a very good thermal sensing of the battery as
well as preventing error in temperature sensing due to loss of contact
under vibrations
Please ensure that the Positive wire is connected to the
Positive connector BTS+ and the negative wire is connected
to the Negative connector BTS–.
