Xantrex Freedom 458 15ft Battery Temp Sensor • 76-0022-00

The Battery Temperature Sensor (BTS) is a replacement BTS designed for the Freedom 458 Inverter/Charger series. Simply connect the ring terminal end to the positive battery post, complete the routing of the RJ11 cable and connect the plug end to the TSC jack on the front of the Inverter/Charger. The BTS has a 15 foot cable.  When the BTS is connected to the unit and the batteries, the charge voltage is controlled based on battery temperature. The charger adjusts the charge voltage to the best level, minimizing water loss in wet cell batteries. Charge voltage regulation optimizes the battery life cycle.
