What our Experts Think

Q&A  

Q: What is the REDARC BCDC1212T used for?
A: A 12A DC-DC battery charger designed to charge auxiliary or trailer-mounted 12V batteries while driving using a vehicle’s 7-pin trailer connection.

Q: What does it do?
A: It converts and regulates vehicle power into a controlled 3-stage charging profile (bulk, absorption, float) to safely charge secondary batteries to full capacity.

Q: What makes it different from a standard isolator?
A: Unlike a basic isolator, it actively boosts or reduces voltage and provides a smart multi-stage charge profile for AGM, gel, flooded, and lithium batteries.

Q: How much current does it draw?
A: It is input current-limited to 12A, making it safe for trailer wiring and 7-pin connectors without heavy rewiring.

Q: Can it charge while driving?
A: Yes, it is specifically designed to charge trailer or auxiliary batteries during vehicle operation (“power without idling”).

Q: What battery types does it support?
A: It supports common 12V battery chemistries including AGM, gel, flooded lead-acid, calcium, and LiFePO4 lithium batteries.

Q: Does it protect the vehicle battery?
A: Yes, it isolates the start battery to prevent discharge while charging the auxiliary system.

 
Maintenance Tips  

• Keep mounting area cool & ventilated: The unit reduces output if overheated, so ensure airflow and avoid engine heat soak for best charging efficiency.
• Inspect wiring & connections regularly: Check RED (input), BROWN (output), BLACK (ground), and BLUE ignition trigger wires for tight, clean, corrosion-free connections to prevent voltage drop and overheating.
• Mount close to auxiliary battery: Short cable runs reduce resistance, heat, and charging losses—critical for consistent 12A output performance.
• Check fuses and inline protection: Ensure all recommended fusing is intact and correctly rated to avoid fire risk or charger shutdown.
• Ensure solid grounding: Poor ground connections are a top cause of charging failure—always use a clean metal chassis or direct battery negative point.
• Verify ignition trigger function (BLUE wire): If used, confirm it only activates when the engine runs; incorrect signals can drain the start battery.
• Avoid moisture & mud buildup: Keep unit protected from water ingress and debris, especially in trailer-mounted installations.
• Watch for thermal derating signs: If charging slows, it’s often heat-related—improve airflow rather than forcing higher load.
