High Output Battery for Versatile Applications

Engineered specifically for the punishing demands of competition-grade car audio, the Energie PR4800 delivers a staggering 4,800 watts of RMS power. This 12-volt battery acts as a massive reservoir of current, ensuring that your high-wattage amplifiers receive the stable voltage necessary for clean, undistorted sound. With a substantial 110Ah rating, it provides the deep energy storage required to sustain heavy bass notes and complex musical peaks without starving your vehicle's electrical system.

Utilizing high-density AGM technology, this battery features a completely sealed, spill-proof construction that thrives in high-vibration environments. The internal mat design allows for rapid energy discharge and recharge cycles, making it far more efficient than traditional lead-acid batteries for rapid-fire acoustic demands. Its rugged assembly ensures that whether you are on the road or at a show, your power source remains reliable and maintenance-free.

The physical presence of this 66 lb energy cell reflects its industrial-strength internal components. By maintaining a lower internal resistance, the PR4800 facilitates a frictionless flow of electricity to your system’s most power-hungry components. This prevents the dimming lights and thermal stress associated with stock batteries, protecting your investment in high-end audio hardware and extending the life of your vehicle's alternator.

Whether used as a primary starting battery or a secondary bank in a multi-battery setup, the PR4800 provides the definitive stability needed for high-fidelity builds. It bridges the gap between daily reliability and competition performance, offering the reserve capacity to play your system longer with the engine off. Claim this professional-grade power solution today to anchor your soundstage with the current it deserves.

Frequently Asked Questions (FAQ)

I connected the power supply, but the voltage display isn't turning on. What’s wrong?

Ensure the "Remote" (REM) terminal is receiving a 12V signal or is jumpered to the Positive (+) terminal. Like a car amplifier, this unit requires a trigger signal to "wake up" the internal circuitry and activate the cooling fans.

The unit is making a loud "clicking" sound and the display is flashing. Is it broken?

This usually indicates a short circuit on the output side or that your total current draw exceeds the unit's capacity. Disconnect your amplifiers and check for stray wire strands touching the chassis before restarting the PR4800.

Can I use this to charge a completely dead AGM or Lithium battery?

It is not recommended as a primary "dead battery" charger. This is a fixed-voltage power supply. Connecting it to a completely flat battery can cause a massive current spike that may trip the unit's internal thermal protection or blow the input fuse.

My voltage drops significantly when the bass hits. Why isn't it staying at 14.4V?

This is often due to "voltage drop" in your DC cabling. Ensure you are using 1/0 AWG pure copper wire for the output. If the wires are too thin or the run is too long, the resistance will cause the voltage to dip before it reaches your equipment.

Is it safe to run this power supply inside a closed trunk or equipment rack?

No. The PR4800 generates significant heat under load. It must have at least 3 inches of clearance on all sides to allow the internal fans to pull in cool air. Running it in a sealed space will lead to a "Thermal Shutdown" within minutes.

Can I link two PR4800 units together to get double the amperage?

You can run them in parallel (Positive to Positive, Negative to Negative), but you must ensure both units are adjusted to the exact same output voltage using a high-quality multimeter to prevent one unit from "back-feeding" the other.

Why does the fan stay on even after I turn off my audio system?

If the "Remote" wire is still receiving 12V, the unit remains active. Ensure your Remote wire is connected to a switched source (like your head unit or a toggle switch) so the power supply shuts down completely when not in use.

Decent Little Battery

I have this wired to a Taramps Smart 5 Bass on 2 Untouchable Sounds LVL2 12s, along with an AGM in front. This little battery does pretty decent when driving down the road. I drop to high 12s full tilt. But stationary. I would not recommend. If you need a second battery to just back up what you already got and don’t need anything major. This will do just the job.
