20AH (30C Discharge) SCiB LTO Lithium Battery

20Ah (35C Discharge) SCiB LTO Lithium Battery

The 20Ah (30C Discharge) SCiB LTO Lithium Battery is built for car audio systems that demand consistent, repeatable power delivery, not just short-lived peak numbers. Constructed using genuine 20Ah Lithium Titanate Oxide (SCiB) cells, this battery is designed to support high-output audio systems where electrical stability, recovery speed, and long-term reliability matter more than marketing figures.

Rather than being a small auxiliary pack, this battery is intended as a serious energy foundation for high-power car audio builds. Its higher per-cell capacity allows it to sustain current delivery over longer periods, making it an excellent choice for daily-driven vehicles, demo systems, and setups that see extended playtime at elevated output levels.

Built Around 20Ah SCiB Cell Architecture

At the core of this battery are 20Ah SCiB cells, chosen for their ability to store more usable energy per cell while maintaining the inherent advantages of Lithium Titanate Oxide chemistry.

Key characteristics of the 20Ah SCiB format include:

• High usable energy per cell

• Stable behaviour under sustained load

• Strong burst capability when required

• Exceptional cycle life compared to conventional batteries

This makes the battery particularly well-suited to systems where power demand is continuous or repetitive, rather than limited to brief transients.

30C Burst Discharge for Real-World Audio Demands

While 20Ah SCiB cells prioritise energy and stability, this battery is still capable of delivering serious current when the system demands it. With a 30C burst discharge capability, the battery can comfortably handle high-current events such as:

• Bass-heavy musical peaks

• Dynamic mid-bass passages

• Competition-style bursts

• Sudden load changes from large amplifiers

This ensures the audio system remains responsive and controlled, even when pushed hard.

Optimised for 14.4 – 15.6V Charging Systems

This battery is designed to integrate cleanly into vehicles operating within a 14.4 – 15.6 volt charging range, making it compatible with a wide range of modern alternator and regulator setups.

Within this window, the battery provides:

• Predictable voltage behaviour

• Fast recovery after load events

• Reduced voltage fluctuation under sustained output

This makes it an excellent match for vehicles that are already electrically healthy, as well as builds where voltage consistency is critical to amplifier performance.

Consistent Power, Not Just Peak Output

Unlike traditional lead-acid batteries that sag under load, or lithium options that prioritise peak figures over usable performance, the 20Ah SCiB LTO battery focuses on delivering power evenly and predictably.

In real car audio systems, this translates to:

• More stable amplifier operation

• Cleaner sound at higher volumes

• Reduced electrical stress during long listening sessions

• Improved system reliability over time

For audiophiles and competitors alike, this consistency is often more valuable than short-lived peak capability.

Designed for High-Output Car Audio Systems

The 20Ah (30C) SCiB LTO Lithium Battery is well suited to:

• High-power daily drivers

• Mid-to-large RMS audio systems

• Vehicles running multiple amplifiers

• Systems that see extended playtime or frequent high-output use

When sized correctly within the overall electrical system, it can function as a primary car audio battery or as part of a larger lithium bank supporting demanding builds.

Long-Term Reliability and Cycle Life

One of the defining advantages of SCiB LTO chemistry is longevity. These cells are engineered to tolerate aggressive charge and discharge cycles without rapid degradation, resulting in:

• Significantly longer service life than AGM batteries

• Minimal capacity loss over time

• Consistent performance even after thousands of cycles

For vehicles that are used regularly, this translates into lower long-term replacement costs and greater confidence in system reliability.

Installation Considerations

As with all lithium batteries, correct installation is critical. The battery should be mounted in a thermally stable interior or boot location, with appropriate cabling and system design to support the intended current demand.

When installed correctly, the battery becomes a dependable part of the vehicle’s electrical system rather than a weak link.

Who This Battery Is For

The 20Ah (35C Discharge) SCiB LTO Lithium Battery is ideal if you are:

• Running a powerful car audio system that demands consistent voltage

• Looking for a lithium solution that handles sustained output gracefully

• Upgrading from AGM or lower-performance lithium options

• Building a system where reliability and sound quality matter as much as output

It is not designed as a gimmick product. It is designed to perform predictably, last long-term, and support serious car audio systems without compromise.
