Screw terminals ensure secure connections, preventing loosening due to vehicle vibration.

3. Easy Installation and Maintenance

The terminal design facilitates tool operation and allows for quick cable connection. Clearly labeled input and output ports reduce installation errors. The removable housing facilitates future inspection and maintenance.

4. Wide Compatibility + Customization Support

Compatible with 12-48V systems, covering automobiles, RVs, yachts, and commercial vehicles. Supports OEM brand customization, structural customization, and packaging adaptation to meet global market demands.

Real-World Application Cases

Case 1: North American Car Audio Upgrade

A professional car audio shop in California upgraded a pickup truck with two 1200W amplifiers. The original single-battery output could not provide stable power, resulting in sound quality distortion and sudden voltage drops. After installing the YIQI DB-21 splitter, the power supply to the two amplifiers was balanced, eliminating distortion issues. The number of main cables was reduced from three to one, resulting in neater wiring in the engine compartment. For three consecutive months of daily use, there were no overheating or voltage anomalies. This product is used in 80% of the audio upgrade projects at this shop.

Case 2: European RV Battery Expansion

A German family RV needed an additional battery to power a 12V refrigerator, lighting, and water pump. The original wiring lacked an expansion port. Using the DB-21 splitter, the main battery power was split, allowing for simultaneous charging of both batteries without conflict. All devices received stable power, with no low-voltage alarms. Installation was completed in 20 minutes, requiring no rewiring. The family drove the RV for 5000 kilometers with reliable power throughout.
