LifePo4 Battery 35Ah-M8

TIT4NIUM 35 Ah-M8 Battery - CCA: 1,300 A LifePo4 13.2 V (19.8 x 16.6 x 17.5 cm)
The Tit4nium battery represents excellence in the high-performance PLUG & PLAY battery sector, combining power, lightness, and reliability.

Superior Performance for Demanding Applications
With a capacity of 35 Ah and a Cold Cranking Amps (CCA) of approximately 1,300 A, this battery is designed to provide immediate and constant power, ideal for:

High-power audio systems up to 2,000 W for daily use and up to 3,000 W for short-duration SPL competitions;

Starting engines up to 3,000 cm³, ensuring quick and reliable starts;

Competition vehicles where weight reduction and energy reliability are essential.

These batteries can also be used in motorhomes and other applications requiring energy storage. They also offer their full potential in everyday vehicles equipped with audio systems, winches, or other high instantaneous electrical loads, or simply for those looking to reduce weight.

Advanced Protection and Management System (BMS)
The TIT4NIUM LiFePO4 35 Ah-M8 13.2 V battery is equipped with four active BMS installed in parallel that continuously monitor and balance individual cells. It offers:

Overcharge protection: Charge voltage limit of 14.7 volts. Once this threshold is exceeded, the BMS protects the cells by transmitting the overvoltage to resistors located on the BMS.

Deep discharge protection: Lower voltage limit of 10.8 volts. Below this threshold, the BMS disconnects the positive terminal of the battery to prevent further discharge and preserve the lifespan of the cells.

Performance optimization: Maximum energy efficiency thanks to perfect and continuous cell balancing and extended lifespan.

Thermal regulation: Guaranteed operation between -20 °C and +70 °C.

Technical Specifications and Dimensions
Nominal voltage: 12.8 V

Resting voltage after charge: 13.2 V

Optimal end-of-charge voltage: 14.6 V

Maximum protection voltage: 15 V

Internal resistance: < 2.8 mΩ

Weight: 4 kg

Battery dimensions 35 A - M8: 19.8 x 16.6 x 17.5 cm (height with terminals). 16.8 cm without M8 bolt.

Advanced LiFePO4 Technology
Lithium Iron Phosphate (LiFePO4) chemistry offers numerous advantages over traditional batteries:

Long lifespan: up to 15,000 charge/discharge cycles, approximately 10 times more than lead-acid batteries;

High safety thanks to the BMS in series with the positive terminal: superior thermal and chemical stability, reducing the risk of fire or explosion.

Low self-discharge: retains its charge even after long periods of inactivity;

Environmentally friendly: free of heavy metals and harmful acids, making it more environmentally responsible.

Compatibility and Installation
The battery is designed to be ready to use, meaning it can be installed in place of the original battery, or ideally in the trunk, close to the main power sources (e.g., audio system). LiFePO4 batteries can be installed in any position and do not require ventilation. They are dry and do not leak, and can even be installed inside the vehicle. As listed, we offer M5, M6, and M8 terminals, or ISO pins depending on the model.

If replacing, you must remove all existing batteries and only use LiFePO4 batteries.

For periods of inactivity exceeding 30 days, we recommend charging with specific LiFePO4 chargers to maintain cell balance. Find our 12 A and above chargers in the dedicated category on our website.

Why choose Titanium batteries?
Titanium batteries are the result of extensive research, testing, and development conducted by GS Audio, a historical leader in battery innovation for automotive and extreme applications. Designed for high performance, they guarantee safety, longevity, and maximum reliability. Compliant with European regulations, they benefit from all CE and ROHS certifications. With an average energy density of 153 Wh/kg, they are among the lightest solutions on the market, far surpassing competing technologies:

- LTO (titanate) ≈ 70 Wh/kg

- Lead-acid AGM ≈ 38 Wh/kg
