Litijska baterija 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 delivers 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 high 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 60 A or less to optimize battery life, although it can accept a maximum charging current of up to 230 A for very fast charging if needed.

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

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

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

The battery's electronic enclosure is protected by a waterproof housing certified to IP65, effectively shielding it from dust and water jets—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) ensures 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 from -25 °C to 50 °C.

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

Yes. It is designed to replace heavy and bulky lead-acid battery banks. It allows for up to 70 % weight and space savings for equivalent usable energy.

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 must then ensure it is recharged every 100 days.

Yes, installing an appropriate 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 deliver a peak current of 1800 A for 10 seconds, it is perfectly suited to start 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.
