Xantrex Heater Blanket For 105AH and 125AH Batteries

The Xantrex Heater Blanket For 105AH and 125AH Batteries is a thermal management solution designed for deep-cycle battery systems in off-grid power applications, marine vessels, and RV installations. Cold weather significantly reduces battery performance and charge acceptance, making thermal protection essential for reliable power delivery during winter months or in harsh climates. This heater blanket wraps around compatible Xantrex battery banks to maintain optimal operating temperature and extend both runtime and service life.

The unit employs a low-wattage heating element that activates in sub-freezing conditions, preventing internal cell resistance from spiking while maintaining chemical reaction efficiency within the battery pack. Engineered specifically for 105-ampere-hour and 125-ampere-hour battery configurations, the blanket provides uniform heat distribution without creating hot spots or thermal stress points. At just 1.2 lbs, the construction balances thermal insulation with minimal weight penalty—critical for mobile applications where every pound matters. The design integrates seamlessly with Xantrex battery systems, using manufacturer-spec connectors and control protocols for automatic temperature regulation.

Off-grid homeowners, RV enthusiasts, and marine operators benefit most from this accessory, particularly in northern climates or seasonal deployments. Installation is straightforward—the blanket wraps around the battery case and connects to the battery's thermal management system or auxiliary power circuit. Users report measurable improvements in charge speed and available capacity during winter operation. Compatibility is limited to Xantrex 105AH and 125AH battery models (MPN 881-0180-12), so verify your battery specifications before purchase to ensure proper fit and electrical integration.
