Xantrex Battery Temperature Sensor (BTS) f/Freedom 458 Series — Product description

Enhance the charging efficiency of your Freedom 458 inverter/charger setup with the Xantrex Battery Temperature Sensor (BTS). This essential accessory ensures your batteries receive optimal charging by automatically adjusting voltage based on real-time temperature readings. Whether you're powering an RV on long road trips, a marine vessel, or an off-grid solar system, maintaining precise battery temperature compensation prevents undercharging in cold conditions or overcharging in heat—ultimately extending battery lifespan and maximizing performance.

Why Temperature Compensation Matters for Your Power System

Batteries perform differently at varying temperatures. In colder environments, chemical reactions slow down, requiring higher charging voltages to fully replenish capacity. Conversely, high temperatures accelerate reactions, risking gassing or damage if voltage isn't lowered. The Xantrex BTS mounts directly to your battery terminal or side post, using a rugged 15-foot cable to connect seamlessly to your Freedom 458 unit. This setup delivers temperature-compensated charging, mimicking the intelligence of advanced battery management systems without the complexity.

Key Advantages of the Xantrex BTS

  • Precision Charging: Real-time temperature sensing adjusts output for up to 20-30% better charge acceptance, depending on conditions.
  • Extended Battery Life: Reduces sulfation in lead-acid batteries and minimizes wear from thermal stress.
  • Simple Integration: Plug-and-play design with no additional programming needed—ideal for DIY installs in RVs, boats, or cabins.
  • Built to Last: Engineered for harsh environments with durable construction that withstands vibration, moisture, and temperature swings.

Effortless Installation Guide

Getting your BTS up and running takes minutes. Clean the battery terminal post or side terminal, secure the sensor ring terminal firmly (torque to manufacturer specs for your battery type), and route the 15-foot cable to your Freedom 458 inverter/charger. Connect to the dedicated BTS port—your system instantly recognizes it and begins compensating. Pro tip: Position the sensor on the negative terminal of the battery farthest from the charger in multi-bank setups for the most accurate average reading across the bank.

Proven Reliability and Certifications

Backed by decades of Xantrex innovation in power electronics, this BTS meets rigorous ISO 9001:2015 standards and complies with UL, CSA, or CE certifications. It's crafted for demanding applications, from recreational vehicles to military-grade systems, ensuring dependable operation year-round. Plus, it comes with a limited 1-year warranty for peace of mind.
