Description
Product Overview
The RecPro RP-9885-125C4 is a high‑capacity 125‑amp power converter designed for mobile environments where dependable DC power is essential. Housed in a robust alloy steel enclosure, the unit resists corrosion and mechanical stress, making it suitable for the rigors of road travel, marine exposure, and outdoor use. It accepts a standard 105‑volt AC input and delivers a steady 16.5‑volt DC output at up to 17 amps, with selectable fixed voltage modes of 13.0 V, 14.6 V, and 16.5 V to match a variety of battery chemistries. The integrated 4‑stage smart charging system—fast, standard, trickle, and equalization—optimizes charge cycles for both lead‑acid and lithium batteries, preserving health and extending service life. Weighing only 3.5 lb and measuring 7.8 × 9.5 × 3.5 in, the converter balances power and portability, while the gray finish blends seamlessly with most vehicle interiors.
Usage
This converter excels in recreational vehicle (RV) setups, providing a reliable source for lighting, appliances, and entertainment systems while the vehicle is parked at a campsite or hook‑up. Boaters benefit from its marine‑grade construction, using it to charge deep‑cycle batteries and power navigation electronics on the water. Automotive enthusiasts install the unit in trucks or custom builds to run auxiliary accessories such as winches, in‑vehicle refrigerators, and high‑performance audio systems without draining the primary battery. Because it supports series and parallel wiring, users can scale power output for larger battery banks, making it a flexible solution for off‑grid cabins, tiny homes, and emergency backup configurations. 
Why Choose Us
RecPro combines engineering precision with field‑tested durability. Each converter undergoes a 1‑year manufacturer warranty, reflecting confidence in component quality and assembly standards. The alloy steel chassis not only protects internal circuitry but also dissipates heat efficiently, reducing the need for additional cooling fans. Our 4‑stage smart charger algorithm continuously monitors battery voltage and temperature, automatically adjusting charge rates to prevent over‑charging and sulfation. Compatibility with both lead‑acid and lithium chemistries eliminates the need for multiple chargers, simplifying inventory for service technicians and DIY owners alike. The unit’s compact footprint and lightweight design enable straightforward mounting in confined spaces, while the clear labeling of input/output terminals speeds up installation.
