Baterie litiu MLI Ultra 24/6000

The MLI Ultra 24/6000 is a 24 V Lithium Iron Phosphate (LiFePO4) battery with a massive capacity of 230 Ah (6000 Wh). It is specifically designed for demanding marine environments and includes an intelligent Battery Management System (BMS).

This battery offers an exceptional lifespan of 3,500 cycles at 80% depth of discharge (DoD) at an ambient temperature of 25 °C.

Yes, the use of an external safety relay is strictly mandatory to ensure absolute safety. For this 24 V model, the compatible reference to add is the Mastervolt 7702B-BSS relay.

The battery weighs 46.7 kg. Its external dimensions, including terminals and transport handles, are 622 x 197 x 355 mm (Length x Width x Height).

The MLI Ultra 24/6000 integrates easily into a modern onboard system thanks to its native compatibility with MasterBus, CZone, and NMEA 2000 networks.

It excels in handling strong currents. It supports a continuous discharge current of 200 A (up to 500 A for 20 minutes) and can deliver an impressive peak of 1800 A for 10 seconds.

The recommended charging current is less than or equal to 60 A to optimize battery lifespan, although it can accept a maximum charging current of up to 230 A for very fast charging if necessary.

The battery should be installed upright whenever possible. However, it can also be mounted on its side along any lengthwise axis depending on your mounting space constraints.

Yes, for installations requiring very high storage capacity, these batteries can be paralleled without limit.

Yes, you can connect up to 10 batteries in series. Note that for systems exceeding 48 V, installation in a separate battery enclosure is required to prevent access to high-voltage components.

The battery’s electronic enclosure is protected by an IP65-rated watertight housing, effectively shielding it from dust and water jets, making it ideal for a marine environment.

It uses Lithium Iron Phosphate (LiFePO4) chemistry, which is recognized as the safest and most stable lithium technology available on the market, with no risk of thermal runaway.

The intelligent BMS (Battery Management System) provides active cell balancing. It continuously monitors the battery and protects it against overvoltage, undervoltage, and extreme temperatures.

The battery can operate safely within an operating temperature range of -25 °C to 50 °C.

The battery is equipped with standard M8 threaded terminals for a solid and secure connection of your power cables.

Absolutely. It is designed to replace heavy, bulky lead-acid batteries. It allows for a weight and space reduction of up to 70% for the same usable energy output.

If you do not use the battery for an extended period, it is recommended to charge it to more than 80% of its capacity before storage. You should then recharge it every 100 days.

Yes, installing a suitable battery fuse (such as a type T fuse) on the positive cable is required to protect your onboard electrical circuit from short circuits.

Yes, thanks to its ability to provide a peak current of 1800 A for 10 seconds, it is perfectly suited for starting heavy loads such as bow thrusters, large inverters, or winches.

If the voltage drops critically (below 22 V), the BMS triggers a safety event. The mandatory safety relay will then open automatically to disconnect the battery from the network and prevent irreversible damage to the cells.
