12V 600Ah service and starting battery

Unlike traditional lithium-ion batteries, this battery uses solid-electrolyte cells (no liquid). The main advantages are:

Absolute safety with no risk of leakage or fire.Extremely low weight (38.5 kg), half the weight of a classic lithium battery and one-sixth the weight of a lead-acid battery.Exceptional energy density of 8640 Wh in a standard format.

Yes, it is specifically designed for mixed use. It provides a continuous discharge current of 250 A to power onboard electronics and winches, while delivering a cold cranking amperage equivalent to 1000 CCA, sufficient to start high-displacement marine engines.

This battery uses the standard Group 8D format. Its dimensions are approximately 52 x 26.8 x 25.4 cm (20.47 x 10.55 x 10.01 inches). It weighs only 38.5 kg (85 lbs), making it significantly easier to handle compared to traditional batteries of the same capacity.

The battery is fitted with M8 terminals. To ensure a secure connection and avoid any damage, it is essential to use a torque wrench. The recommended tightening torque is between 10 and 12 Nm. Never tighten the connections by hand only.

Absolutely. Its ABS housing has IP67 certification, meaning it is fully protected against dust and can withstand temporary immersion in water. It is perfectly suited to harsh marine conditions.

You can monitor the battery directly from your smartphone (iOS or Android) using the free SSM Battery Monitor HP app via the built-in Bluetooth connection. Depending on the variant selected at purchase, you can also integrate it into your onboard network via NMEA 2000, Victron, CAN, or RS-485.

Yes, the battery is delivered with a partial charge for safety reasons during transport. It is crucial to fully charge it to 16.6 V before first use to calibrate the system and avoid irreversible damage.

To fully utilize the solid-electrolyte battery's capacity, the charging voltage must be set higher than a standard lithium battery. Configure your charger to 16.5 V - 16.6 V in expert mode. Disable float voltage and temperature compensation, and set the tail current to 10 A for this 600Ah model.

Yes, it includes a very advanced battery management system (BMS). The BMS immediately cuts power in case of a short circuit (1000 A protection in 2 milliseconds). It also blocks charging and discharging if the internal temperature exceeds 65°C (150°F), and automatically reactivates once the temperature drops.

The battery allows use (discharge) and charging down to -20°C (-4°F). If the temperature drops below this threshold, the BMS will automatically cut off charging and discharging to protect the cells, and will resume operation once the temperature rises again.

Thanks to solid-electrolyte technology, this battery is designed to withstand over 3,000 charge and discharge cycles, offering significantly greater longevity than traditional lead-acid batteries for intensive marine use.

For long-term storage, charge the battery between 30% and 80% of its capacity, then physically disconnect it from the system. Store it in a clean, dry, and well-ventilated area, protected from direct sunlight. It is recommended to recharge it every 3 to 6 months to prevent deep discharge.

Yes, the internal management system allows series and parallel connections. You can configure up to 2S4P (2 in series, 4 in parallel) to adjust the voltage and total capacity to your service battery bank.

To protect the cells, the BMS automatically cuts discharge when the voltage drops to 10.08 V. In this case, the battery will still allow an incoming charging current. Immediately disconnect consuming devices and start charging to reactivate the battery.

Yes, the mobile app has specific modes (series or parallel). If you have connected multiple batteries together, the app will scan and display all batteries within range, allowing you to monitor the charge state and parameters of each one centrally.
