Description
xVictron Peak Power Pack 12.8V / 20Ah 256Wh Lithium Battery
The Victron Peak Power Pack is a self-contained 12.8V lithium iron phosphate (LiFePO4) battery unit rated at 20Ah and 256Wh. It is designed for portable power applications, small off-grid setups and auxiliary power where a compact, ready-to-use energy store is needed without additional battery management hardware.
Key Features
- 12.8V nominal voltage with 20Ah capacity, delivering 256Wh of usable energy from a LiFePO4 cell chemistry.
- Built-in battery management system (BMS) handles cell balancing, over-charge, over-discharge and short-circuit protection.
- Compact and lightweight at 3.96kg, making it practical for portable and mobile installations.
- LiFePO4 chemistry offers a stable discharge curve, low self-discharge and a significantly longer cycle life than lead-acid equivalents.
- Ready to use out of the box with no external BMS or additional management hardware required.
- Compatible with Victron chargers and charge controllers configured for lithium battery profiles.
Product Overview
The Peak Power Pack uses lithium iron phosphate cells, which operate at a nominal 12.8V rather than the 13.2V of some other lithium chemistries. This makes it a closer drop-in match for 12V lead-acid system voltages, though charge parameters must still be set correctly for lithium. The integrated BMS removes the need for a separate protection board, keeping the installation simple and the footprint small.
At 256Wh, this unit suits applications where moderate energy storage is needed in a portable or space-constrained format. The LiFePO4 chemistry is thermally stable and tolerates deep discharge better than lead-acid, which means the full rated capacity is genuinely usable in practice. Cycle life is substantially higher than sealed lead-acid, reducing replacement frequency over the life of an installation.

Installation Notes
The Peak Power Pack includes an integrated BMS, so no external battery management hardware is required. Ensure any charger or solar charge controller is set to a lithium (LiFePO4) charge profile before connecting. Do not use charge parameters intended for lead-acid batteries. For installations forming part of a larger electrical system on a vessel or vehicle, connection should be carried out by a qualified electrician familiar with lithium battery systems.
