Rafgeyms 12,8V/200Ah NG

This battery uses Lithium Iron Phosphate (LiFePO₄ or LFP) technology, known for its safety, long lifespan, and thermal stability.

The Victron Energy 12.8V/200Ah NG battery has a nominal capacity of 200 Ah and a nominal energy of 2560 Wh at 25 °C.

The cycle life of this battery is excellent, with:

2,500 cycles at 80 % depth of discharge (DoD)3,000 cycles at 70 % depth of discharge (DoD)5,000 cycles at 50 % depth of discharge (DoD)These figures are based on a residual capacity of at least 80 % of the nominal capacity.

The battery has the following dimensions (height x width x depth): 235 x 341 x 160 mm. Its estimated weight is 19 kg.

The Victron Energy Lithium NG battery has an IP65 protection rating. This means it is effectively protected against dust ingress and can withstand low-pressure water jets, making it suitable for environments where exposure to dust and water is a concern.

Yes, a Battery Management System (BMS) is mandatory and must be purchased separately. The BMS ensures automatic configuration, monitoring, and control of battery parameters, protecting the cells from overcharging, deep discharges, and extreme temperatures.

The Lithium NG batteries are compatible with Victron Energy BMS units, such as the Lynx Smart BMS NG 500A/1000A, the smallBMS NG, and the VE.Bus BMS NG. Other models may also be compatible.

Yes, you can connect multiple Victron Energy Lithium NG batteries in series, parallel, or a combination of both to create battery banks suited to your requirements.

You can use a maximum of 50 batteries when configuring an array with 12 V or 24 V batteries. For systems using 48 V batteries, a maximum of 25 batteries can be used.

These batteries can be connected to create systems with nominal voltages of 12V, 24V or 48V, depending on the series and parallel configuration chosen.

Depending on the system configuration, you can achieve a maximum energy storage capacity of:

Up to 192 kWh with 12V batteriesUp to 384 kWh with 24V batteriesUp to 128 kWh with 48V batteries

The battery can be installed using straps or mounting brackets, which are included. It can also be placed on its side, offering installation flexibility.

For discharging, the operating temperature range is -20 °C to +50 °C. For charging, the operating temperature range is +5 °C to +50 °C. It is important to respect these ranges to preserve battery lifespan and performance.

Power connections are made via M8 terminals (threaded inserts and bolts). The BMS interface uses a male + female cable with an M8 circular connector for high-speed digital communication, 50 cm in length. M8 extension cables are available separately.

Yes, a full initial charge of the battery is mandatory before its first use. This ensures all cells are balanced and the battery is ready to operate at its optimal capacity.

For a 12.8V system, the recommended charge voltage is between 14 V and 14.4 V. The recommended float voltage is 13.5 V.

The Victron Energy 12.8V/200Ah NG battery can handle a maximum continuous discharge current of 200 A (1C).

Real-time monitoring of battery parameters, such as cell status and voltages, current, and temperature, is possible via:

The VictronConnect application (Bluetooth)A GX communication centerThe VRM portalBattery firmware is automatically updated by the BMS.

A battery management system (BMS) is mandatory for the Victron Energy Lithium NG 12.8V/200Ah battery. It must be purchased separately.

The BMS automatically manages all battery parameters, detects system voltage and the number of connected batteries. It performs critical functions such as:

Generating a pre-alarm when a cell's voltage drops.Looping the load if a cell's voltage drops too low.Stopping the charging process if a cell's voltage is too high or if the temperature is out of limits.The Lynx Smart BMS NG 500A/1000A is an example of a compatible and required BMS for this battery range.

Yes, Victron Energy Lithium NG 12.8V/200Ah batteries can be connected in series, parallel, or a combination of both to create battery banks suitable for 12V, 24V, or 48V system voltages.

You can connect:

Up to 50 batteries for 12V or 24V systems.Up to 25 batteries for 48V systems.This allows for significant energy storage capacities, for example up to 192 kWh with 12V batteries.
