Aku 25,6 V/300Ah NG

The Victron Energy 25.6V/300Ah NG battery uses Lithium Iron Phosphate (LiFePO₄ or LFP) technology.

This battery has a nominal voltage of 25.6 V and a nominal capacity of 300 Ah. Its nominal energy is 7680 Wh.

The cycle life of this battery is 2,500 cycles at 80% depth of discharge (DoD) and can reach up to 5,000 cycles at 50% depth of discharge (DoD).

The battery can be charged at temperatures between +5 °C and +50 °C. For discharging, the temperature range is -20 °C to +50 °C.

The Victron Energy 25.6V/300Ah NG lithium battery has an IP65 protection rating. This means it is effectively protected against dust and can withstand low-pressure water jets.

The battery dimensions are 206 mm (height) x 841 mm (width) x 205 mm (depth). Its estimated weight is 52 kg.

Yes, Victron Energy Lithium NG batteries, including the 25.6V/300Ah model, include cell balancing and monitoring.

The internal resistance of the Victron Energy 25.6V/300Ah NG battery is 1 mΩ.

The self-discharge rate of this battery is a maximum of 3 % of its capacity per month at 25 °C.

Yes, using a Battery Management System (BMS) is mandatory. The Victron Energy 25.6V/300Ah NG battery must be used with a Lynx Smart NG BMS (500 A or 1000 A), which must be purchased separately.

You can connect up to 50 Victron Energy 25.6V batteries in parallel in a 24V system. This allows reaching a maximum energy storage capacity of 384 kWh per BMS.

No, the Victron Energy 25.6V/300Ah NG battery is specifically designed for 24V energy systems.

Battery monitoring and parameter tracking are performed via the VictronConnect app (each BMS model includes Bluetooth), a GX communication center, or the VRM portal. You can view real-time data such as cell status, cell voltages, battery current, and temperatures.

The battery can be mounted using straps or the included mounting brackets. It can also be placed on its side for installation.

The battery power connections are M8 type, using threaded inserts and bolts.

When handling or installing, wear safety glasses and protective clothing, and use insulated tools. Avoid placing metal objects on the battery, as the terminals are always live. Handle the battery carefully due to its weight and sensitivity to mechanical shock. Do not open or disassemble the battery.

Yes, it is recommended to perform a full initial charge of the battery before its first use to ensure all cells are balanced and the battery is ready to operate optimally.

The battery must be transported in its original packaging or equivalent, in an upright position. Transport cartons or crates must bear an approved warning label. It falls under UN3480, Class 9, Packing Group II, and must be transported according to P903 regulations for land and sea transport.

No, air transport of lithium batteries of this type is prohibited under current regulations.

The Victron Energy 25.6V/300Ah NG battery requires a Victron Energy-approved NG-type Battery Management System (BMS) to function correctly and safely.

Specifically, a Lynx Smart BMS NG 500 A or 1000 A is mandatory. This BMS must be purchased separately.

The BMS is essential as it automatically manages all battery parameters, monitors system voltage and the number of connected batteries. It also balances cells and implements critical protections, such as disconnecting the load in case of low voltage or stopping charging in case of high voltage or abnormal temperature.
