Renogy REGO 12V/24V 30A Bidirectional DC-DC Battery Charger

Renogy REGO 12V/24V 30A Bidirectional DC-DC Battery Charger

The Renogy REGO 12V/24V 30A Bidirectional DC-DC Battery Charger is designed for vehicle, RV, marine, and off-grid electrical systems that need intelligent charging between a starter battery and an auxiliary or house battery.

Its bidirectional design allows energy to move between the starter and auxiliary battery systems when needed, helping maintain both battery banks while supporting mixed 12V and 24V installations.

Bidirectional Battery Charging

The REGO charger is built to manage power between starter and auxiliary battery banks rather than working only in one direction. This makes it useful for mobile power systems where maintaining the starter battery is just as important as charging the house battery.

12V and 24V System Support

Support for 12V and 24V battery systems gives the charger flexibility across RVs, vans, trucks, marine systems, service vehicles, and other mobile or off-grid applications. Boost and buck operation allows compatible systems to charge across different battery voltages.

Battery Compatibility

The auxiliary-battery side supports multiple battery chemistries and user-defined charging profiles, including:

• Lithium
• AGM
• Sealed lead-acid
• Flooded lead-acid
• Gel
• User-configurable charging mode

Smart Monitoring & Control

Bluetooth and wired CAN communication provide intelligent monitoring and control options within compatible Renogy energy-management systems. Users can monitor charging behavior and adjust supported charging parameters for the installation.

Built for Mobile Power

With a compact footprint, wide operating-temperature range, and intelligent protection system, the REGO charger is well suited for installations where space, reliability, and battery management are important.

Package Includes

• REGO bidirectional DC-DC battery charger
• Quick installation guide
• Battery temperature sensor
• Mounting hardware

Installation

Proper cable sizing, overcurrent protection, grounding, battery settings, alternator capacity, and system compatibility should be verified before installation. For vehicle and off-grid electrical systems, professional installation is recommended when system requirements exceed the installer’s experience.
