## Overview

The X300 300 CCranking Amp Hybrid Capacitor/Battery is a compact, high-performance 12V power solution combining capacitor speed with battery capacity. Delivering 300 amps peak and 3.5 Ah capacity, it discharges energy almost instantaneously to prevent power sags in audio systems while protecting your car battery from drain. With a 3 to 6 year cycle life and flexible installation options, it’s engineered for professionals demanding reliable, fast, and efficient power delivery.

## Description

12 Volt 3.5 Ah 300 Amps Peak 1 Hour at 3.5 Amps Draw 5 Minutes at 20 Amp Draw Cycle Life 3 to 6 Years 4.5 MilliOhm Internal resistance per cell 6 Cells Dimensions 5 - 5/8 in X 4 - 1/8 in X 3 1/8 in Weight 3 Lbs. Can be put in Parallel for more current draw for longer periods of time Can be put in Series for a higher Voltage Unlike conventional capacitor bank, Batcap X400 WILL NOT draw current when ACC is off. Therefore you wont experience flat battery even if you dont start the car for 10 days. And it is SAFE for European Car. In terms of SQ, you can expect the following result: 1. Better definition and clarity 2. Better weight 3. Better ambience THE STORY BEHIND BATCAP: A conventional battery, as we all know has a positive and negative terminal. The chemical reaction within creates a flow of electrons, causing an electronic device (in this case an amplifier) to work. The stiffening capacitor is similar to a battery in that it stores a charge. The fundamental difference is it cannot create electrons. It can only store and supply (discharge) them upon demand. The advantage with a capacitor is that it discharges in one twenty thousandth of a second, unlike a battery that does in one second. The battery therefore cannot discharge fast enough to effectively supply the amplifier and this is the reason for power sags. WAKE UP! Dont fall asleep just yet, were getting to the exciting part! The XSTATIC BATCAP is simply a BATTERY that can discharge just AS QUICKLY AS a capacitor. Therefore, you have a constant supply of electrons that will discharge at lightning speed. This puts less strain on your stock alternator and battery. It also recharges faster than a conventional battery since the internal resistance is low. How about the install? Well Im sure you can find a place to put this 3 lb baby. Dont let the size fool you though.

Review: less than desired - upon arrival, the BATCAP plastic casing had been shattered. completely broken. i patched it up with some hot glue and re-sealed it then installed it. PROS: better than 1F Electrolytic no pre-charging to install, just hook it up and go - you won't blow any fuses CONS: case was completely shattered when it arrived - needs better packaging. much better. 100F?? with 50-60A draw, there is still light dimming no holding capacity (it can't hold its charge without a constant supply) 1-3 minute charge time required before "louder than normal" operation due to above condition
