Arrives before Christmas 
Stay off-grid longer with a power kit built for the road less traveled. Redarc's smart charging system delivers reliable battery power through every leg of the journey - whether you're driving, parked, or chasing the sun.
The BCDC Trailer S isn't just a charger - it's a fully integrated power solution. It combines a DC-DC charger, an MPPT solar controller, and a battery isolator in one compact unit. Built specifically for trailers, it draws power from your vehicle's alternator through the 7-way plug and accepts solar input simultaneously. That means there's no need to run extra wiring to your vehicle's start battery. The installation requires wiring into your trailer's battery system and solar panel, so it's not plug-and-play - but it's a manageable project for anyone comfortable working with power systems. Once it's ready, your auxiliary battery stays charged, no matter where the road leads.
What sets the BCDC apart isn't just where it pulls power from - it's how it treats your battery. The advanced multi-stage charging algorithm is designed to deliver a safe, complete charge without overdoing it. First, a boost stage delivers consistent voltage to kick things off. Then it transitions into absorption, holding steady to fully charge your battery without overshooting. Finally, it enters a float stage, maintaining charge levels without pushing too hard. The result? Longer battery life, dependable power, and less time worrying about what's happening under the hood.
Power shouldn't be a mystery when you're out in the wild. The Redarc Smart Battery Monitor gives you full visibility over your system - from state of charge to real-time current draw and voltage. It connects to your smartphone via Bluetooth, giving you reliable access to your battery data even when you're working around camp or driving down the road.
When you're counting on the sun, the 80-watt monocrystalline panel delivers high-efficiency output in a compact footprint. And those solar cells are protected by a sturdy aluminum frame and tempered glass. It's made to ride on rooftops and withstand harsh weather while you're riding through rough trails. With the BCDC's built-in MPPT controller, every watt gets put to work.
