Xantrex Battery Temperature Sensor (BTS) f/Freedom SW Series

Meet the Xantrex Battery Temperature Sensor (BTS) for Freedom SW Series — a smart accessory that feeds precise temperature data to your charger to optimize charging for your battery bank. It’s designed for Freedom SW 2000, 3000, 2000 24V, and 3000 24V systems, helping you maximize performance and extend battery life in varying temperatures.

• Temperature-compensated charging: Adjusts the charger’s voltage in response to ambient temperature to help achieve a full, optimized charge across varying conditions.
• Flexible mounting: Easy installation that mounts on a terminal post or on the side of a battery for versatile setups in a battery bank.
• Extended communications cable: 25 ft (7.6 m) of communications cable enables convenient placement in large battery banks.
• Wide compatibility: Works with Freedom SW 2000, 3000, 2000 24V, and 3000 24V models.
• Continuous temperature monitoring: The BTS continuously monitors temperature and communicates with your charger to deliver the right amount of power when it’s needed.
• Intelligent charger communication: Intelligent data exchange with your charger ensures temperature-compensated charging for a safe, efficient full charge.
• Usage note: This BTS is designed to enhance charging efficiency by providing precise temperature data to your charger, helping ensure your batteries reach and maintain full capacity under real-world conditions.
• Prop65 Warning: This product can expose you to chemicals including Diisononyl Phthalate (DINP) which is known to the State of California to cause cancer, and Di-isodecyl Phthalate (DIDP) which is known to the State of California to cause reproductive harm.
