2. Introduction
The Lithium SuperPack NG batteries are Lithium Iron Phosphate (LiFePO₄ or LFP) batteries available in various capacities with nominal voltages of 12,8V, 25,6V, and 51,2V. They are designed as drop-in replacements for lead-acid batteries in mobile, marine, and industrial applications. Designed for extended off -grid use, it provides ample capacity to power the complete electrical system, including high -demand appliances. Its form factor and terminal layout ensure easy installation across a wide range of mobile and industrial applications, including commercial and recreational vehicles.
2.1. Features
Embedded protection
The integrated Battery Management System (BMS) provides a layer of protection that ensures energy flow remains within the safe operating limits of the battery and the overall system.
Energy flow management
Capable of interrupting charging and discharging independently through its self-resetting circuit breaker.
Continuous current capability
Supports continuous discharge currents up to 2C and continuous charge currents up to 1C, reducing the need to oversize the battery pack.
Internal cell balancing
Allows the battery to maintain optimal voltage balance at the end of the charging process.
Bluetooth monitoring and control
Integrated Bluetooth interface for real-time monitoring and control of the battery via VictronConnect.
On/Off push button
Push button for switching the battery on or off, disabling both charging and discharging. The on/off procedure can also be used to reset certain protection or lock-in conditions. When switched off, the battery enters a storage mode with a self-discharge rate of less than 3% per month.
LED status indication
Two integrated LEDs indicate Bluetooth connectivity, warning and alarm conditions, and firmware update status.
External Feedback Signal (EFS)
Provides a battery voltage signal limited to 250 mA. The EFS signal serves as an External Disconnection Signal (EDS) to trigger an event for redundant system protection. Additionally, the EFS can be configured as an External Charging Signal (ECS), based on the low SoC pre-alarm threshold, to activate a charger start signal.
Self -heating function
Maintains the battery temperature above the minimum safe charging limit to ensure reliable operation in cold environments. Two heating modes are available:
Charger mode – the heater is powered by the connected charger and activates automatically when the cell temperature drops below 0 °C during charging (default setting).
Auto mode – the battery powers the heater to keep the cells above 0 °C for immediate charging. This is limited by the battery’s internal energy; if SoC falls below the Low SoC threshold, the heater is disconnected and charging remains unavailable.
The internal heat balancer supports optimised thermal management and a wide operating range.
High efficiency
Operating efficiency 93 %
High round-trip efficiency
High energy density (up to 170 Wh/dm³ and 128 Wh/kg) - more capacity with less weight and volume
Parallel connection
Supports parallel connection of an unlimited number of batteries to increase total energy capacity. The total system current should not exceed the maximum current that a single battery can safely interrupt (refer to Battery Specification for details.
BCI Group 49 compatibility
Height dimension is compatible with the BCI Group 49 standard, allowing easy replacement in standard battery compartments.
Mounting brackets
Mounting brackets are included to ensure safe and stable fixing in all three axes.
Ingress protection (IP65)
The battery enclosure is rated IP65, providing protection against dust ingress and low-pressure water jets from any direction.
Self-restoring protection
Certain protection events are automatically cleared without user intervention. The battery allows multiple automatic recovery attempts for short-circuit and over-current conditions, reducing the need for manual reset in the case of occasional or transient faults. For details, please see the Self-restoring protection mechanisms section.
Safety vent (3/4” threaded connection)
The battery is equipped with a safety vent featuring a 3/4” internal thread for connection to a gas discharge fitting. A suitable gasket must be used to ensure a proper seal. The vent is intended exclusively for the controlled release of gases in the event of extreme fault conditions. It must not be used for cooling or for the connection of liquids or other media.
