12V 330Ah 6TL House Battery

Unlike traditional lithium batteries (LFP), our solid-state battery contains no liquid electrolyte. This completely eliminates the risk of thermal runaway and fire. Additionally, it is twice as light as a standard lithium battery while offering significantly higher energy density.

Yes, absolutely. This is a dual-purpose battery. With a cold-cranking amperage (CCA) rating of 1000 and the ability to deliver 500 A peaks for 60 seconds, it is perfectly suited for starting marine engines while powering demanding onboard systems.

Yes, the design of these batteries allows series and parallel connections. You can create setups up to 2S4P (2 in series for a 24V system, and up to 4 in parallel to increase the overall capacity of your bank).

To achieve a full charge and unlock all performance, the battery requires a charging voltage of 16.5 V to 16.6 V. Standard lithium chargers often max out at 14.4 V. We recommend using configurable chargers, such as Victron models (IP43 or IP65), by creating a custom charge profile.

The battery features native Bluetooth connectivity. Simply download the free SSM Battery Monitor HP app (available on iOS and Android) to view real-time state of charge (SOC), voltage, current, and temperature.

The battery is fitted with robust M8 terminals. During installation, a torque wrench must be used and a tightening torque of 10 to 12 Nm applied. Insufficient tightening can damage the terminals or create a hazardous electrical resistance.

Yes, this is one of the major advantages of semiconductor-based technology. Unlike conventional lithium batteries, this battery allows safe charging and discharging down to -20°C (-4°F). The integrated BMS automatically shuts down the system if the temperature falls outside the safety range.

This 6TL model is extremely compact for its massive 330 Ah capacity. It measures 34.9 x 11.1 x 28.9 cm and weighs only 23.6 kg (52 lbs), making it much easier to install in tight boat bilges.

The advanced BMS protects the battery against numerous risks:

Overvoltage and undervoltageOvercurrent (up to 500 A for 60s)Short circuits (up to 1000 A for 2 ms)Extreme temperaturesIt also provides passive cell balancing to maximize lifespan.

Yes, the battery is specifically designed for harsh marine environments. It features a robust ABS housing with IP67 certification, providing effective protection against water and dust.

Yes, if you choose the +NMEA variant. This option enables the battery to communicate via the NMEA 2000 protocol, allowing you to monitor the status of your battery bank directly from the screen of your compatible marine chartplotter.

Yes, the battery is offered in several variants to suit your installation. When placing your order, you can select specific variants that include Victron, CAN or RS-485 protocols for seamless integration with your existing equipment.

If the voltage drops below 10.08 V, the BMS cuts the discharge to protect the cells. The battery can still accept a charging current. You must disconnect the loads and immediately turn on your charger to reactivate the battery and prevent irreversible damage.

Solid-state technology does not use a liquid electrolyte, which completely eliminates the risk of thermal runaway and fire, even in the event of physical damage.

Reduced weight: At just 23.6 kg for 330 Ah, it is half the weight of a standard lithium battery.Cold performance: Unlike conventional lithium, it allows safe charging and discharging down to -20°C.Energy density: Its compact 6TL format maximizes the available space in your boat’s bilges.

To fully utilize this battery’s capacity, a configurable charger capable of reaching a charging voltage of 16.5V to 16.6V is required.

Standard lithium battery charge profiles (often limited to 14.4V) will not allow a full charge. It is recommended to use configurable chargers where you can set an absorption voltage of 16.5V, disable the float voltage, and adjust parameters according to the specifications required for lithium technology.

Yes, this battery is specifically designed for dual-purpose use. It excels in both applications:

Starting: It delivers a cold cranking amperage (CCA) of 1000 A and supports discharge peaks up to 500 A. Service: Its massive capacity of 330 Ah and tolerance for continuous discharge up to 250 A reliably power the most demanding onboard electrical systems.
