48V 120Ah Service Battery

Unlike traditional Lithium Iron Phosphate (LFP) batteries that use a liquid electrolyte, this battery features solid-state cells. This innovative design completely eliminates the risk of combustion and thermal runaway. Additionally, it delivers exceptional energy density, making it twice as light as a standard lithium battery at equal capacity.

This model weighs only 27.2 kg (60 lbs), which is extremely light for a 6048 Wh energy reserve. It is designed to the standard BCI Group 8D format, with dimensions of 52.0 x 26.8 x 25.4 cm (20.47 x 10.55 x 10.01 in).

The Solid State Marine battery is designed to last over 3000 cycles with an 80% depth of discharge (DoD). Its advanced battery management system (BMS) passively balances the cells to maximize longevity and maintain optimal performance over the years.

Yes, it is perfectly suited to the harshest marine environments. It has an IP67 rating, making it fully water-, salt-, and dust-resistant. The housing is made from highly robust flame-retardant ABS plastic.

The battery comes with built-in Bluetooth connectivity. You can monitor state of charge (SOC), voltage, current, and temperature in real time by downloading the free SSM Battery Monitor HP app, available for iOS and Android smartphones.

Absolutely. These batteries support series and parallel connections. According to the manufacturer's specifications, you can create configurations up to 2S4P (2 in series, 4 in parallel) to increase the overall voltage or capacity of your service battery bank.

Yes, this battery is offered with several advanced communication options to integrate with your onboard electronics. When placing the order, you can select the +NMEA 2000, +Victron, +CAN or +RS-485 variants to display data directly on your chartplotter or energy management system.

Use a charger with a lithium battery profile. Set the charge voltage to 58.1 V. The recommended charge current is 60 A (the BMS maximum is 100 A to 120 A), though a standard 20 A charge is ideal for cell longevity.

For long-term storage, charge the battery between 30% and 50% of its capacity, then disconnect it completely from the system. Store it in a dry, well-ventilated location (between -20°C and 40°C). It is recommended to recharge it every 3 to 6 months to avoid accidental deep discharge.

The BMS (Battery Management System) continuously monitors each cell. It automatically disconnects the circuit in case of overvoltage (above 58.8 V), undervoltage (below 35.28 V), extreme temperatures (cutoff at 70°C), overcurrent, and short circuits (up to 1000 A).

Yes, with its large 120Ah capacity (6048 Wh) and nominal voltage of 48V, it is ideal for electric propulsion or high-demand service battery banks. It allows a continuous discharge current of 250 A and accepts power peaks up to 500 A.

It is crucial not to tighten the terminals by hand alone. Use a torque wrench to tighten the M8 bolts provided with a recommended torque of 10 to 12 Nm. Incorrect tightening can cause increased resistance, overheating, and severe damage to the terminal.

The battery activates automatically as soon as a load (consuming equipment) is applied to it or when a charger is connected and operating. Simply ensure all your cables are properly sized and securely tightened before powering up your system.

Yes, solid-electrolyte technology offers excellent thermal performance. The battery can safely discharge down to -20°C (-4°F). However, to protect the cells, the BMS will block any attempt to recharge if the internal temperature drops below -20°C.

Yes, it is essential to protect your installation with appropriate fuses placed as close as possible to the battery. The fuse rating must be matched to the cross-section of your cables and your maximum consumption. While the BMS includes internal short-circuit protection, an external fuse remains mandatory according to marine installation standards.
