24V 150Ah service + start battery

Unlike traditional lithium batteries (LiFePO4), solid-state technology (Solid-State) uses no liquid electrolyte. This makes it completely non-flammable and exceptionally safe for marine use. Additionally, it offers higher energy density, providing more power in a more compact and lighter format.

Yes, the architecture of these batteries allows for multiple connections. You can connect them in series and parallel, with a recommended maximum limit of 2 in series and 4 in parallel (2S4P), enabling you to create a battery bank perfectly suited to your boat's power requirements.

Yes, if you select the +NMEA option when placing your order. This option integrates the NMEA 2000 protocol, allowing the battery to communicate directly with your chartplotter or multifunction displays to show charge status and other critical data.

The battery comes with Bluetooth as standard. Simply download the free SSM Battery Monitor HP app (available on iOS and Android) to monitor the state of charge (SOC), voltage, temperature, and other vital parameters in real time directly from your smartphone.

The battery is fitted with M8 terminals. It is essential to use a torque wrench and apply a tightening torque between 10 and 12 Nm. Never tighten connections by hand only, as poor contact could damage the battery.

This battery delivers excellent performance at low temperatures. It can continue to discharge and operate down to -20°C (-4°F). The integrated Battery Management System (BMS) automatically protects the battery by blocking charging if the temperature drops below this threshold, and reactivates it as soon as conditions allow.

Despite its large 3780 Wh capacity, the battery is extremely compact. It uses a standard Group 31 format (approximately 34 x 18.5 x 25 cm) and weighs only 17.5 kg (38 lbs). This is roughly half the weight of a conventional lithium battery and one-sixth the weight of a lead-acid battery of equivalent capacity.

The battery has a robust ABS casing with IP67 certification, making it highly resistant to dust and water splashes. However, for safety reasons, it is strictly inadvisable to install it in an area prone to flooding or submersion (such as the bilge of an undrained hull).

For optimal winter storage:

Charge the battery between 30% and 80%.Physically disconnect the battery from the boat's system.Store it in a dry, ventilated place, away from direct light.Recharge it at least once every 3 to 6 months to prevent deep discharge.

These options allow the battery to integrate seamlessly with your boat's electronic ecosystem:

+Victron: Optimized for communication with Victron Energy equipment (Cerbo GX, etc.).+NMEA: For direct connection to the onboard NMEA 2000 network.+CAN/+RS-485: Industrial protocols for specific or custom energy management systems.

Solid-state batteries offer maximum safety on board as they contain no liquid electrolyte, making them completely non-flammable. Additionally, they are approximately twice as light as traditional lithium batteries (LiFePO4) and provide higher energy density, allowing for more energy storage in a compact format (standard BCI Group 31).

Yes, this battery is designed for mixed use. It delivers a continuous current of 250 A to power your onboard equipment, while being capable of delivering peaks up to 350 A, with a starting power equivalent to 1000 CCA. This simplifies the boat's electrical installation by combining house and starting power.

The battery includes Bluetooth connectivity so you can monitor it easily from your smartphone. Simply download the free SSM Battery Monitor HP app (available on iOS and Android) to view real-time state of charge (SOC), voltage, and other parameters. Advanced communication options such as NMEA 2000, CAN, or RS-485 are also available depending on the chosen variant for direct integration with your chartplotter.

Absolutely. Unlike standard lithium batteries, which often go into safety mode as soon as the temperature approaches 0°C, this solid-state battery maintains excellent performance in cold conditions. Its intelligent Battery Management System (BMS) allows charging and discharging down to -20°C without requiring a complex internal heating system.

You can use a charger with a lithium battery charging profile. The charging voltage must be set to 29.4 V ± 0.6 V. The integrated BMS automatically manages passive cell balancing and protects the battery, with a recommended maximum charging current up to 75 A (0.5C).
