OBSOLETE - MLS 24 V 260 Ah Lithium-ion battery

The MLS 24/260 battery is designed for applications requiring a small 24V storage capacity. It is ideal for directly replacing traditional lead-acid batteries in small boats, security systems, or uninterruptible power supplies (UPS), offering significant weight and space savings.

This battery uses Lithium Iron Phosphate (LiFePO4) technology. It is one of the safest and most stable lithium chemistries on the market, offering excellent lifespan and high safety for marine use.

The battery has a nominal voltage of 24V (25.6V when open-circuit) with a capacity of 10 Ah, providing a total energy reserve of 256 Wh.

No, series mounting is strictly prohibited by the manufacturer for this model. A series connection would irreparably damage the internal Battery Management System (BMS).

No, using the MLS 24/260 battery as a starter battery is not recommended. It is designed for service use (slow and continuous discharge), and its maximum discharge current is not suitable for the high current demands of engine starters.

The battery is extremely compact and lightweight. It weighs only 3.1 kg. Its dimensions, including the terminals, are 180 mm long, 77 mm wide, and 161 mm high.

Vertical installation is recommended. However, side mounting (at 90 degrees) is also permitted by the manufacturer, providing flexibility for tight spaces.

The battery housing and its integrated electronic circuit breaker have an IP65 protection rating. This means it is fully protected against dust and water jets, making it perfectly suited to damp marine environments.

This battery's lifespan exceeds 2000 cycles at an 80 % depth of discharge (DoD). This represents a longevity roughly three times greater than that of a traditional lead-acid battery.

Yes, it is equipped with an integrated battery management system (BMS). This system ensures automatic and secure disconnection in case of overvoltage, undervoltage, or abnormal overheating.

It is essential to use a battery charger with an IUoU charge characteristic compatible with Lithium-Ion technology, capable of providing the specific voltages required by Mastervolt.

For optimal charging, the charger must be set to an absorption voltage (Bulk/Absorption) of 28.5 V and a float voltage (Float) of 27.0 V.

The battery allows a maximum continuous discharge current of 10 A (which corresponds to 1C, i.e., 100% of its nominal capacity).

Yes, it can handle discharge pulses up to 25 A for 30 seconds, and very brief peaks of 48 A for a maximum of 2 seconds.

The battery is equipped with M5 threaded insert terminals. It is recommended to use suitable lugs and tighten the connections to a torque of 2 to 3 Nm.

Yes, if you install multiple batteries side by side, you must leave a space of more than 2 cm between each unit to ensure proper heat dissipation.

The self-discharge rate is extremely low, at less than 2% per month at a temperature of 20°C. This allows it to be stored for several months without requiring constant recharging.
