Pro Chaser DC-DC Step Down Converter for Golf Carts & RVs — 48V/36V to 12V, Sealed Aluminum, Harness Included

The Pro Chaser DC-DC Step Down converts 48V or 36V vehicle battery packs into a safe, reliable 12V output for lights, radios and accessories.

Built specifically for golf carts and RVs that use 36V (six 6V batteries) or 48V (six 8V batteries) battery packs, this Pro Chaser converter supplies a stable 12V feed for low-voltage accessories without tapping into fragile battery circuits. The unit arrives with a matched harness and fitted butt connectors for a straightforward plug-and-play installation, and its aluminum-cast, ventilated shell provides cooling with a sealed, water-resistant exterior for outdoor vehicle use.

How does the Pro Chaser converter protect my vehicle’s 12V accessories?

This step-down module regulates higher battery voltages down to a consistent 12V, preventing over-voltage spikes that can damage lights, radios, USB chargers and other accessories. It also isolates accessory circuits from the main propulsion batteries for more reliable operation.

• Converts 36V or 48V battery packs into stable 12V output
• Sealed, water-resistant aluminum casing resists moisture and dust
• Ventilated design reduces heat buildup during continuous use
• Includes harness and butt connectors for secure electrical joins

What’s involved in installing the DC-DC step down on a golf cart or RV?

Installation is designed to be user-friendly: match the included male and female harness connectors, secure the fitted butt connectors, and mount the converter where it gets airflow while remaining protected from direct water spray. The last product photo provides a wiring guide to follow during installation.

• Plug-and-play matched harness simplifies hookup
• Butt connectors reduce need for soldering or extra crimps
• Mount on frame or inside compartment with good ventilation
• Follow photo guide for wiring orientation and safety tips

Which accessories can I power with this 12V output?

The converter can run common 12V loads found on golf carts and RVs, such as head- and tail-lights, radios, GPS units, interior lights, and small solar charge controllers. It’s intended for low-voltage accessories rather than high-draw propulsion systems.

• Headlights and tail-lights
• Radios, speakers, and navigation electronics
• Interior lighting and accessory outlets
• Small solar panels or charge controller inputs (check draw limits)

How durable and weatherproof is the converter for outdoor use?

The Pro Chaser unit features a cast-aluminum shell with targeted ventilation to shed heat while remaining sealed against water ingress, making it suitable for vehicles exposed to the elements. Laser-printed labeling helps you identify wiring without worrying about ink wear in wet conditions.

• Aluminum cast housing for mechanical strength and heat dissipation
• Sealed, water-resistant case suitable for vehicle environments
• Laser-printed marking for long-lasting identification
• Compact footprint fits into under-seat compartments or lockers

Who is this for: The Pro Chaser DC-DC Step Down is for golf cart and RV owners who use 36V or 48V battery packs and need a reliable, weather-resistant 12V source for lights and accessories. It’s a good option for DIY installers, fleet managers, and anyone upgrading older vehicles to power modern electronics without modifying the main battery architecture.
