Description
xVictron Lithium SuperPack 12.8V 100Ah (M8)
The Victron Lithium SuperPack 12.8V 100Ah is a self-contained LiFePO4 battery designed for marine, mobile and off-grid applications where a drop-in lithium replacement for lead-acid is needed. It includes an integrated Battery Management System (BMS), removing the need for external BMS hardware in single-battery installations. Suited to professional installers and system integrators working on 12V DC systems.
Key Features
- 12.8V nominal voltage with 100Ah capacity, giving 1.28kWh of usable energy in a compact form factor.
- Lithium Iron Phosphate (LiFePO4) chemistry offers a stable, thermally safe cell with a long cycle life compared to lead-acid or other lithium chemistries.
- Integrated BMS handles cell balancing, over-charge protection, over-discharge protection and short-circuit protection without requiring external components.
- M8 terminal connections provide a secure, high-current bolted connection suitable for professional wiring installations.
- Weighs 10.5kg, significantly lighter than an equivalent lead-acid battery, reducing overall system weight in mobile and marine installations.
- Designed as a direct replacement for 12V lead-acid batteries in many applications, simplifying retrofits and upgrades.
- Victron product, compatible with the wider Victron Energy ecosystem including MPPT charge controllers and MultiPlus inverter/chargers when configured correctly.
Product Overview
The SuperPack range differs from Victron's Smart Lithium batteries in that the BMS is fully integrated within the battery casing. This makes it a self-contained unit: no external BMS, no additional cabling between battery and protection board, and no VE.Bus or VE.Direct BMS communication required for basic operation. For single-battery installations or straightforward 12V systems, this simplifies the bill of materials and reduces installation time.
LiFePO4 chemistry is the preferred choice for stationary and mobile energy storage where safety and longevity matter. The chemistry is inherently more stable than NMC or NCA lithium cells, with a lower risk of thermal runaway. Cycle life is substantially higher than lead-acid, making the higher upfront cost recoverable over the life of the installation. The 100Ah capacity at 12.8V gives a usable energy figure that, unlike lead-acid, can be drawn down to a much deeper state of discharge without damaging the cells.
The M8 terminal variant uses M8 bolt connections, which are standard in professional DC wiring and compatible with most marine and vehicle cable lugs. This is the correct choice where a secure, vibration-resistant terminal connection is required. Ensure your charge source is set to a LiFePO4 charge profile before connecting.

Installation Notes
This battery must be charged using a charger or charge controller configured for LiFePO4 chemistry. Do not use a standard lead-acid charge profile. The integrated BMS provides cell-level protection, but it does not replace correct system design: fusing, cable sizing and charge source compatibility must all be verified before installation. For installations forming part of a solar PV system or a vessel's electrical system, connection by a qualified electrician or accredited installer is recommended. The SuperPack is not designed for series connection to increase voltage. Parallel connection to increase capacity is possible but should be carried out in accordance with Victron's published guidance for this battery series.
