Victron Peak Power Pack 12.8V 20Ah 256Wh LiFePO4 Battery | PPP012020000

The Victron Peak Power Pack is a self-contained 12.8V lithium iron phosphate (LiFePO4) battery rated at 20Ah, giving 256Wh of usable energy. It ships with a built-in battery management system, so no separate BMS or protection board is needed for portable or small off-grid setups.

Key features of this LiFePO4 battery

• Voltage and capacity, 12.8V nominal, 20Ah, 256Wh of usable energy.
• Chemistry, Lithium Iron Phosphate (LiFePO4) cells with a stable discharge curve and low self-discharge.
• Integrated BMS, manages cell balancing, over-charge, over-discharge and short-circuit protection.
• Weight, 3.96kg, compact enough for mobile installations.
• Ready to use, no external BMS or additional management hardware required.
• Charger compatibility, works with Victron chargers and charge controllers set to a lithium battery profile.

Product overview

Running at 12.8V nominal rather than the 13.2V of some other lithium chemistries, this pack sits closer to a drop-in replacement for 12V lead-acid systems, though the charge profile still needs to be set for lithium. The integrated BMS keeps the unit self-contained, and deep discharge is tolerated far better than with lead-acid, so the rated 256Wh is genuinely usable. Cycle life is also higher than sealed lead-acid, which cuts down on replacements over time.

Applications

The Peak Power Pack suits portable power stations and field equipment, auxiliary power for campervans, caravans and narrowboats, small off-grid lighting or monitoring systems, backup power for low-draw 12V devices and instrumentation, and marine auxiliary use where weight and space are limited.

Installation notes

Set any charger or solar charge controller to a lithium (LiFePO4) profile before connecting; lead-acid charge parameters are not suitable. On vessels or vehicles forming part of a larger electrical system, connection should be handled by a qualified electrician familiar with lithium battery installations.
