Xantrex Heater Blanket 30W & 10A Temperature Switch Kit

Keep Your Lithium Batteries Performing in Freezing Conditions

Imagine heading out for a winter camping trip in your RV or tackling a long-haul route in your heavy-duty truck, only to find your lithium battery struggling in sub-zero temperatures. Lithium batteries can lose significant capacity and charging efficiency when cold, leading to frustrating power shortages. That's where this innovative heater blanket steps in, delivering targeted warmth to maintain optimal battery performance without wasting energy.

Crafted for rugged mobile environments, it wraps securely around specific lithium battery sizes, activating only when temperatures drop below a safe threshold. This smart approach ensures your power system remains reliable, whether you're booting up navigation systems on a foggy marine morning or powering tools on a work truck site.

Standout Features for Reliable Cold-Weather Operation

• Precise Temperature Management: Built-in switch monitors ambient conditions, engaging the 30W heating element at just the right moment to prevent battery degradation.
• Energy-Efficient Design: Draws minimal power—only when needed—maximizing your overall system runtime and preserving precious battery life.
• Durable Construction: Tough materials withstand vibrations, moisture, and harsh weather, ideal for off-grid adventures or demanding job sites.
• Simple Integration: Tailored fit for popular lithium battery models, with straightforward wiring to your 12V system for plug-and-play reliability.

Real-World Benefits That Power Your Lifestyle

Users rave about how this heater blanket transforms cold-weather reliability. In marine applications, it keeps batteries ready for starting engines or running electronics during chilly dawn patrols. For RV enthusiasts, it means uninterrupted climate control and lighting on snowy getaways. Truck operators appreciate the consistent power for telematics and refrigeration units, avoiding costly downtime.

By maintaining batteries above critical temperature thresholds, it extends lifespan, improves charge acceptance rates, and boosts overall discharge performance—translating to fewer replacements and more dependable power on the move.

How the Temperature-Controlled Heating Works Seamlessly

The 10A temperature switch acts as the brain, sensing when conditions dip and signaling the 30W blanket to generate gentle, even heat. This self-regulating system cycles on and off automatically, hugging the battery cells without overheating. No manual intervention required—just consistent warmth that mimics ideal operating conditions, even in -20°F extremes.

Paired with lithium's fast-charging nature, it ensures quick recovery times, letting you top up power rapidly once warmth is restored.

Perfect Fit for Your Mobile Power Needs

Engineered to conform precisely to 105Ah G31 or 125Ah G27 lithium batteries, installation is a breeze: wrap, secure with straps, connect to your DC bus, and you're set. It's a game-changer for setups where space is tight and reliability is non-negotiable.

Versatile Applications Across Demanding Sectors

Backed by Decades of Mobile Power Innovation

Drawing from extensive experience in RV and marine power systems, this kit embodies proven engineering for real-world challenges. It's not just a heater—it's a safeguard for your investment, designed to integrate smoothly with broader power ecosystems for off-grid freedom.

Quick Installation Tips for Peak Performance

Mount the blanket on the battery's underside or side away from exhaust heat sources. Route wires cleanly to avoid chafing, and test the switch function in controlled cold conditions before full deployment. Regular checks ensure long-term efficiency, especially in high-vibration environments.
