It works with both conventional and smart (variable-voltage) alternators, and its alternator running detection makes sure it only draws power when the engine is actually charging, protecting the starter battery from being drained.\u003c\/p\u003e\n\u003cp\u003eCharging efficiency reaches 94%, and the multi-stage charging logic adapts output to the battery for a safer, more complete charge. A supplied battery temperature sensor feeds real-time data for precise adjustments, and the charger automatically scales back output when temperatures run high. Lithium battery activation can be toggled on or off to suit your setup.\u003c\/p\u003e\n\u003cp\u003eThe compact, corrosion-resistant housing cools passively for quiet operation, which makes it a good match for vans, trucks, and boat cabins. Add a Renogy BT-2 Bluetooth module to monitor the charger remotely and review up to 365 days of recorded data in the app.\u003c\/p\u003e\n\u003ch4\u003eWhat's in the Box\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e1 x DC to DC Battery Charger\u003c\/li\u003e\n\u003cli\u003e1 x Battery Temperature Sensor (2 m)\u003c\/li\u003e\n\u003cli\u003e1 x IGN Signal Wire (3 m)\u003c\/li\u003e\n\u003cli\u003e4 x Terminal Rings\u003c\/li\u003e\n\u003cli\u003e1 x User Manual\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Renogy","offers":[{"title":"40A","offer_id":46209717829823,"sku":"RBC40D1U-US","price":186.99,"currency_code":"USD","in_stock":true},{"title":"20A","offer_id":46209717862591,"sku":"RBC20D1U-US","price":140.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0708\/1967\/6351\/files\/RNG-260901-M9-_1-24.jpg?v=1789528365","url":"https:\/\/adventuremotion.com\/products\/renogy-12v-20a-40a-dc-to-dc-battery-charger","provider":"Adventure Motion","version":"1.0","type":"link"}
