Pro Chaser DC-DC Step-Down Converter 48V/36V to 12V — Sealed Aluminum Housing with Matched Harness

Pro Chaser’s DC-DC step-down converter safely reduces 36V or 48V battery packs to a stable 12V output for lights, radios and accessories in golf carts and RVs.

This compact, sealed converter is built to work with common golf cart and RV battery arrangements — either a 36V pack (six 6V batteries) or a 48V pack (six 8V batteries). It supplies a reliable 12V feed to run headlights, taillights, stereo systems, solar controllers and other 12V accessories without tapping the main pack directly. The unit includes a matched harness and butt connectors for a clean, removable install and features an aluminum cast shell with ventilation and water-resistant sealing for outdoor use.

The converter is made specifically for vehicles that use six-battery configurations at 36V or 48V. It connects inline to the battery pack using the supplied harness and fitted butt connectors so you don’t need to rewire major circuits. Installation follows the included wiring reference photo.

• Compatible with six 6V (36V) or six 8V (48V) battery packs

What devices can I power with this 48V/36V-to-12V step-down?

The converter provides a regulated 12V output suited for common 12V loads found on carts and trailers. It’s ideal for lighting, entertainment, charging small electronics and feeding solar charge controllers that expect a 12V source. Avoid connecting high-draw appliances beyond the unit’s rated capacity.

• Headlights, taillights and marker lights
• Radios, speakers and small infotainment systems
• 12V solar controllers and auxiliary accessories
• Accessory charging ports for phones and small devices

How durable and weatherproof is the unit for outdoor use?

The converter uses an aluminum cast housing with a sealed, water-resistant enclosure to stand up to damp conditions and outdoor exposure. Laser-marked surface printing resists fading, and the vented design helps dissipate heat during extended operation. Still, mount it in a sheltered location when possible to maximize lifespan.

• Aluminum cast shell for heat dissipation and ruggedness
• Completely sealed, water-resistant case for outdoor environments
• Laser-printed labeling for long-lasting identification
• Ventilation features to avoid overheating under load

How simple is the installation and maintenance?

Installation is straightforward for anyone comfortable with basic vehicle electrical work: connect the harness, secure the butt connectors, and follow the gallery’s wiring photo. No complex programming is required. Periodic checks of connections and mounting points are all that’s typically needed for reliable service.

• Plug-in harness reduces wiring errors and speeds installation
• Fitted butt connectors provided for robust electrical joins
• Follow included photo guide for correct wiring orientation
• Minimal maintenance beyond visual connection checks

Who this is for: Pro Chaser’s DC-DC step-down is suited for golf cart and RV owners who need a dependable 12V source from a 36V or 48V battery pack without rewiring the vehicle. It’s a practical choice for fleet operators, weekend RVers, and do-it-yourself technicians who want a sealed, easy-to-install converter built to withstand outdoor conditions while powering lights, radios, and small accessories.
