xVictron Energy Peak Power Pack 12.8V / 40Ah – 512Wh Lithium Battery
The Victron Energy Peak Power Pack is a self-contained 12.8V lithium iron phosphate (LiFePO4) battery unit designed for portable power, off-grid applications and auxiliary power needs. With 512Wh of usable energy in a compact, sealed enclosure, it suits installers and professionals who need a reliable, ready-to-use lithium battery without building a custom battery bank.
Key Features
- 12.8V nominal voltage with 40Ah capacity, delivering 512Wh of usable energy from a LiFePO4 cell chemistry.
- Lithium iron phosphate chemistry offers a stable discharge curve, long cycle life and inherent thermal stability compared to other lithium chemistries.
- Integrated battery management system (BMS) provides cell balancing, over-charge, over-discharge and short-circuit protection.
- Compact, self-contained unit weighing 7.25kg, making it practical for mobile, marine and portable installations.
- Victron Energy manufacture, backed by the brand's established support network and compatibility with Victron charge controllers and inverter-chargers.
- Drop-in replacement form factor for 12V lead-acid battery positions in many existing installations.
Product Overview
The Peak Power Pack uses lithium iron phosphate cells, which operate at a nominal 12.8V rather than the 12V of a lead-acid equivalent. This slightly higher resting voltage is characteristic of LiFePO4 and means existing 12V Victron chargers and inverter-chargers set to a lithium profile will charge it correctly. The flat discharge curve of LiFePO4 means the battery delivers close to its rated voltage throughout most of its discharge cycle, which is practically useful for inverters and DC loads that are sensitive to voltage drop.
The integrated BMS is a key part of this product. It manages cell balancing and protects against the conditions that shorten lithium battery life or create safety risks: overcharge, deep discharge and excessive current draw. Because the BMS is built in, there is no need to source or wire an external protection board, which simplifies installation and reduces the component count in smaller systems.
At 7.25kg, the Peak Power Pack is significantly lighter than a comparable lead-acid battery. This matters in weight-sensitive applications such as campervans, narrowboats and portable power stations. The sealed enclosure also means it can be mounted in orientations that would not be suitable for flooded lead-acid batteries.

Installation Notes
The Peak Power Pack should be charged using a charger or charge controller with a lithium (LiFePO4) charge profile. Using a standard lead-acid charge profile risks overcharging the cells and will void any warranty. Ensure the charge voltage is set correctly for 12.8V LiFePO4 chemistry before connecting. For installations in vehicles or vessels, secure the unit against movement and ensure adequate ventilation around the enclosure. While the integrated BMS provides protection, a suitably rated fuse should still be fitted as close to the battery terminal as practical. For solar system integration, installation by a qualified electrician or MCS-accredited installer is recommended.
