CS-Batteries Lithium Batteries for Cars

Buy CS Batteries Cheap Online – Your Car Audio Online Shop Masori

In our car audio online store Masori, you will find a wide selection of CS batteries specifically designed for car audio applications and mobile energy storage. The LiFePO4 technology (lithium iron phosphate) provides high power reserves for subwoofer-strong car sound systems. Thanks to advanced design, these batteries are characterized by low weight and a compact form factor. For hybrid installations or large amplifier setups, the powerful 12V series is ideal for achieving outstanding sound quality.

Basic Characteristics and Types of LiFePO4 Batteries

CS-Batteries offers different capacities and designs to support every car audio requirement. Depending on the variant, nominal voltages between 12.0 V and 12.8 V are available. Capacities range from 15 Ah to 300 Ah, allowing you to choose a suitable battery depending on the power requirement. These batteries operate with very low internal impedance, which is especially important for power-oriented applications such as car audio subwoofer configurations.

• Operating voltage: 10.0 – 14.6 V
• Lifecycles: Up to 3000 cycles at 100% depth of discharge
• Maximal discharge rate: Up to 3C (depending on the model)
• Recommended charging method: CC/CV (Constant Current/Constant Voltage)
• Connection: M6 or M8 threaded bolts, partly plug-and-play capable connections

The designs differ in terms of size, weight, and connection technology. Compact models fit perfectly in vehicles such as VW, BMW, or SEAT, while larger capacities are used in Mercedes or Opel for demanding car audio upgrades.

Efficient accessories and installation options for in-car installation

When installing a CS battery in a car, it is important to use suitable accessories and ensure a secure installation situation. Ideally, you should use special brackets or battery holders designed for LiFePO4. Tight-fitting mounting brackets provide stability to minimize vibrations and mechanical stress. Appropriately sized cable cross-sections are required for connection to amplifiers or DSP modules to reduce voltage losses.

• Flexible OFC cables in 25 mm² or more for high current applications
• Special fuse holders such as ANL or Mega-Fuse for short-circuit protection
• Cable lugs with robust ring terminal design for good contact
• Optional battery monitor for monitoring voltage and current values

Those who do not want to install it themselves can use our professional service. The Masori team offers an installation service in Frankfurt Oder (https://masori.de/pages/einbauservice) for professional installation.

Useful Chargers and Design for High Current Loads

The CS Batteries LiFePO4 batteries require specific chargers for optimal charging, which provide voltage- and current-controlled phases. Typically, a constant current phase is used for rapid energy intake, followed by a constant voltage phase to balance high final currents. Charging currents can be up to 50 A, depending on the battery capacity. Included LED indicators or LCD displays show the current charging status.

For plug & play solutions in Audi, VW, BMW, or other vehicle manufacturers, it is important that the charger is equipped with a digital battery management system tailored to LiFePO4 technology. This prevents exceeding temperature or current limits.

Spectrum of Application Areas and System Integration in the Vehicle

CS batteries are convincing not only in classic car audio setups but also in motorhomes, boats, or accumulator-based camper electronics. Those who need powerful auxiliary electronics for DSP amplifiers, digital sound processors, or high-power amplifiers will benefit from the high discharge currents. Due to their low self-discharge, the LiFePO4 batteries are also suitable for seasonal use, such as in show cars or weekend vehicles, without the need for constant recharging.

If needed, you can contact our expert support directly (https://masori.de/pages/faq-und-hilfe) or consult the interactive AI chatbot to ensure that the selected components are compatible with your car. In addition to the voltage specifications, individual requirements such as installation locations, pole arrangement, and cable routing are also taken into account there.

Practical notes on installation steps and acoustic optimization

To ensure your car audio system unleashes the full power of the CS batteries, you should consider a few installation aspects. Thoughtful placement in a well-ventilated area in the trunk or under the rear seat reduces unwanted heat buildup. Check that the battery is securely fastened and protected against shocks. Especially with low-frequency subwoofers, a stable power supply is crucial to handle load peaks without voltage drops.

• Decoupling measures with rubber inserts against vibrations
• High-quality mass connections on the body or battery negative terminal
• Short cable runs to amplifiers or DSPs for low voltage loss
• Observance of correct polarity when connecting to the charge controller

For deep frequencies and powerful kick basses, a combination of CS batteries and powerful Class-D amplifiers is recommended to ensure optimal headroom for your car audio system.

Variability of technical data for every sound enthusiast

The LiFePO4 series from CS-Batteries is available in a variety of technical versions. Those planning only a subtly upgraded audio system expansion can start with 20 Ah to 50 Ah. For complex multi-channel configurations with multiple amplifiers, however, a capacity of 80 Ah or higher is recommended. A low ESR (Equivalent Series Resistance) enables rapid current draws – this is especially essential for kick bass and powerful subwoofer passages. With a constant discharge power of up to 200 A in the larger series models, multiple amplifiers remain stably supplied at all times.

In addition, the temperature tolerance of the CS batteries is adapted to various climate conditions. At very cold temperatures, it is advisable to use a thermal management system to protect the battery from excessive cooling. To ensure safe charging in the car even under extreme summer conditions, many variants are equipped with integrated BMS modules.
