12V 210Ah dual-purpose battery (house + start)

Unlike traditional lithium iron phosphate (LiFePO4) batteries, the solid-state technology eliminates the liquid electrolyte entirely. This makes the battery non-flammable and ensures absolute safety for your boat, even in the event of perforation or physical damage.

Yes, this is a dual-purpose battery. It delivers strong starting power equivalent to 1000 CCA to crank your engine, while providing deep-cycle capability thanks to its high capacity of 210 Ah (3024 Wh) to power your onboard equipment.

The battery has built-in Bluetooth connectivity. Simply download the free SSM Battery Monitor HP app (available on iOS and Android) to monitor your battery bank’s charge state, voltage, and temperature in real time.

Yes, Solid State Marine batteries can be connected in series and parallel. The maximum allowed configuration is 2 in series and 4 in parallel (2S4P), allowing you to easily increase either the voltage or capacity of your battery bank based on your power needs.

To achieve a full and optimal charge, the battery must be charged at 16.5 V. While a standard lithium charger can work, it must be configurable. We recommend chargers such as the Victron IP43 or IP65 (over 15A) configured with a custom charge profile.

Absolutely. One of the major advantages of this technology is its exceptional thermal tolerance. It can be safely charged and discharged at temperatures ranging from -20°C to 70°C (-4°F to 155°F), without requiring an internal heating system.

Yes, we offer a specific variant with the +NMEA option. This option lets you connect the battery directly to your boat’s NMEA 2000 network and monitor all its data directly from your chartplotter.

The cable cross-section depends on the maximum expected load. For example, for a current of 105 A, a 6 AWG (13.3 mm²) cable is recommended. For higher currents up to 405 A, use 4/0 AWG (107 mm²). Always size your cables according to the amperage of your system.

The terminals use M8 bolts. It is crucial to use a torque wrench and tighten the bolts to a torque between 10 and 12 Nm. Never tighten by hand only to avoid poor contact, overheating, and potential damage.

The battery has an IP67 protection rating, providing excellent resistance to water and dust. However, for safety and durability reasons, it must be installed in a clean, dry, and well-ventilated area, avoiding bilges that may flood.

The integrated BMS has ultra-fast short-circuit protection (trips at 1000 A in 2 milliseconds). If activated, the BMS immediately shuts down the battery for safety. It will remain disconnected until you remove the cables to resolve the electrical fault.

For long-term storage, charge the battery between 30% and 80%, then physically disconnect it from your system. Store it in a dry place between -20°C and 45°C. It is recommended to recharge it every 3 to 6 months to keep the cells healthy, then fully charge it before the next season.

Solid-state technology eliminates the liquid electrolyte found in traditional lithium batteries (LiFePO4). This makes it completely non-flammable and ensures absolute safety, even if punctured.

Weight and space savings: It weighs about half as much as a standard lithium battery (only 12.7 kg for 210Ah) while offering exceptional energy density. Thermal tolerance: It can be safely charged and discharged across extreme temperatures from -20°C to 70°C without requiring an internal heating system.

To fully utilize the capacity of this lithium battery, it is essential to use a charger capable of reaching a charging voltage of 16.5V to 16.6V.

A standard lithium charger set to 14.4V will not allow for a full charge. It is strongly recommended to use programmable chargers (such as certain Victron IP43 or IP65 models over 15A) and configure a custom charge profile to reach this specific voltage.

Yes, this battery is specifically designed for dual use, combining deep discharge and high instantaneous power.

For house loads: It offers a significant capacity of 210 Ah (3024 Wh), providing sustained power for your onboard equipment. For engine starting: It delivers impressive power equivalent to 1000 CCA, more than sufficient to start most marine engines. Its standard BCI Group 27 format makes installation straightforward as a direct replacement for your old lead-acid or AGM batteries.
