Features

⚡ Plug-and-Play Design – Simple connection; no need for complex wiring or extra charging circuits.

💡 Built-In Precharge Bulb – Automatically limits inrush current. The bulb lights up when charging and dims as the capacitor fully charges—no manual precharge required.

🔋 Voltage Stabilization – Maintains consistent system voltage for amplifiers and accessories, reducing dimming and protecting sensitive electronics.

🚗 Dual Compatibility – Works seamlessly with both Lithium and AGM 12V systems.

❄️ Extreme Climate Performance – LTO ultracaps deliver dependable power even in hot or freezing environments.

🔁 Ultra-Long Life – Rated for over 1,000,000 charge/discharge cycles, offering reliable performance for 10+ years.

🧩 Expandable System – Multiple JL-20F units can be connected in parallel to build a larger, high-current energy bank.

How It Works

The JL-20F acts as a power buffer between your battery and high-draw components (such as amplifiers or starters). When voltage dips under heavy load, the capacitor bank releases stored energy instantly to maintain stable voltage. It then recharges in seconds, ready for the next demand.

This not only improves amplifier performance but also extends the lifespan of your battery, starter, relays, and other electrical components by reducing strain and voltage fluctuations.

Applications

Car Audio Systems (1,000W–6,000W setups)

Engine Starting Support

High-Power DC Systems

Off-Road & Marine Vehicles

Hybrid Battery Assist Systems

Package Includes

1 × Blurred Vision Audio JL-20F Super Capacitor Bank

Built-In Precharge Bulb (Integrated)

Mounting and Connection Hardware

Quick Setup

1. Connect 4-gauge input to battery positive (+).

2. Connect output leads to amplifier or power distribution block.

3. Connect ground to chassis or negative battery terminal.

4. Observe the precharge bulb — it will light up during initial charge and fade as full charge is reached.

5. Once the bulb dims completely, the capacitor is ready for use.
