Abyss Battery  Bi-Directional DC-DC Charger - AB-MDX13-60

 The  from Abyss Battery is a marine-grade, high-performance power management device designed to transfer electrical energy seamlessly between different battery systems. Its bi-directional functionality allows it to operate as both a charger and a converter, making it suitable for managing 12V and 36V lithium battery systems onboard boats.

Materials and Construction: The charger features a corrosion-resistant aluminum casing with marine-grade sealing, ensuring durability in harsh marine environments. Internally, it employs electronic components rated for continuous operation at a maximum output of 720W, with protection circuits against overcurrent, overvoltage, and thermal overload for enhanced reliability.

Dimensions and Weight: The unit measures approximately 12 inches in length, 8 inches in width, and 4 inches in height, with an estimated weight of 4.5 kilograms. It is designed for easy installation within standard marine battery compartments or electrical panels.

Features
  • Bi-directional power transfer capabilities facilitate charging and power sharing between 12V engine and 24V/36V lithium systems
  • Maximum output power of 720W (12V 60A) for efficient charging of lithium batteries
  • Adaptive transfer mode based on battery status and load demands
  • Built-in protection features include overcurrent, overvoltage, thermal regulation, and short-circuit protection
  • Compatible with lithium, AGM, and lead-acid batteries, emphasizing versatility for different marine applications
  • Battery management system integration supports optimal charge cycles and prolongs battery lifespan
  • LED indicators display operational status, voltage levels, and fault conditions
  • Weather-resistant construction ensures sustained operation in marine environments
What our Experts Think
  • True bi-directional energy management – The AB-MDX13-60 intelligently transfers power both ways, charging 36V/24V lithium trolling systems from 12V alternators and sending power back to maintain the starter battery when the engine is off.
  • High-output 720W performance – Delivers up to 12V 60A input power, enabling fast recharge of large lithium banks and significantly reducing downtime between fishing runs.
  • Marine-grade IP67 protection – Fully sealed, die-cast aluminum construction ensures reliable operation in wet, saltwater, and high-vibration environments.
  • Smart automatic switching – Software-controlled logic automatically manages boost (12V → 36V) and buck (36V → 12V) modes with no manual intervention required.
  • Ultra-efficient power transfer – Achieves up to ~95% efficiency, minimizing energy loss and maximizing usable onboard power.
  • System simplification advantage – Reduces or eliminates the need for separate house batteries, cutting weight, wiring complexity, and installation cost.
  • Advanced safety integration – Built-in protections against over-voltage, over-temperature, and short circuits ensure stable operation in demanding marine conditions

Q: Can it be used in boats or RVs?
A: Yes, it is ideal for marine and RV applications where multiple battery banks and reliable power transfer are required.

Q: Does it include battery protection features?
A: Yes, it includes over-voltage, over-current, short-circuit, thermal protection, and intelligent charging control for safe operation.

Maintenance Tips
  • Install in a dry, well-ventilated marine area with proper airflow for passive cooling
  • Ensure secure mounting to prevent vibration damage during boating
  • Use correct wire gauge + external fusing (no built-in fuse) for safe operation
  • Keep all connections tight, clean, and corrosion-free (critical for marine environments)
  • Avoid water spray exposure despite IP67 sealing and protect connectors
  • Do not connect or disconnect under load to prevent arcing or damage
  • Regularly inspect cables, terminals, and insulation for wear or overheating
  • Maintain proper voltage range (12V ↔ 24V/36V system compatibility) to avoid fault triggers
  • Keep unit free of salt buildup and moisture contamination
  • Allow natural cooling clearance (no obstruction on all sides) for thermal efficiency
  • Monitor LED status indicators (charge, standby, fault) for early issue detection
  • Avoid operation in extreme heat beyond rated derating limits (~40°C+)
  • Ensure system wiring is installed per manufacturer diagram (boost/buck direction correct)
  • Periodically verify system health and battery communication (CAN/RS485 if used)
  • Store boat system powered off when idle to minimize sleep-mode drain efficiency loss
