An end of train (EOT) system includes monitoring equipment with a sensor to monitor a pressure of air in a brake mechanism in a railcar, and a power supply having battery cells and a temperature control system for the battery cells. The temperature control system includes a heat sink in heat transference contact with the battery cells, and an electronically controlled heater for the battery cells. The temperature control system includes a temperature sensor, and a control device coupled with the temperature sensor and the electronically controlled heater to vary an output of the heater based on an output of the temperature sensor.
