The Victron Lithium SuperPack 25.6V/50Ah is a self-contained LiFePO4 battery with a built-in Battery Management System. It suits off-grid, marine and mobile power setups where a compact, ready-to-use lithium battery is needed without external BMS wiring or protection circuitry.

Key features of this victron lithium battery

• Voltage and capacity, 25.6V nominal, 50Ah, giving 1,280Wh of usable energy in one unit.
• Integrated BMS, handles cell balancing, over-charge, over-discharge, short-circuit and over-temperature protection internally.
• LiFePO4 chemistry, a stable discharge curve, high cycle life and thermal stability compared with other lithium chemistries.
• M8 terminals, secure, low-resistance connections for high-current cabling.
• Parallel capable, batteries can be connected in parallel to add capacity; series connection is not supported.
• Weight, 12.3 kg, considerably lighter than a lead-acid battery of equivalent capacity.

Product overview

The SuperPack range differs from Victron's Smart Lithium batteries by keeping the BMS fully self-contained. There are no external BMS cables, no VE.Bus or VE.Direct ports, and no protection parameters to configure. It is a drop-in lithium upgrade for systems where simplicity matters more than deep integration with Victron's monitoring ecosystem.

At 25.6V nominal, it suits 24V system architectures. The flat LiFePO4 discharge curve keeps system voltage stable across most of the discharge cycle, which benefits inverters and other voltage-sensitive loads. In a parallel bank, each battery runs its own internal BMS independently, so there is no single point of failure. Use equal cable lengths and cross-sections across parallel connections to balance current distribution.

Applications

• 24V off-grid solar storage for cabins, outbuildings and remote sites.
• Marine house battery banks on sailing and motor vessels.
• Mobile and vehicle-based power, including campervans and specialist vehicles.
• 24V DC backup power for telecoms, security and industrial equipment.

Installation notes

Fitting should be carried out by a qualified electrician or system integrator familiar with lithium battery systems. Correct fusing, cable sizing and a charge source that supports LiFePO4 voltage profiles remain the installer's responsibility. Series connection of SuperPack units is not supported. In marine installations, mount the battery securely in a ventilated location according to applicable standards.
