12V/20Ah Lithium SuperPack Battery

Technical Specifications

The Victron Energy Lithium SuperPack is a compact 12.8V LiFePO₄ battery designed for reliable energy storage in RVs, marine applications and off-grid systems. Its integrated Battery Management System (BMS) and safety switch provide protection against overcharging, excessive discharge and temperature-related conditions, without requiring a separate BMS.

FEATURES

• Integrated BMS and safety switch: Automatically disconnects the battery when operating limits are exceeded.

• LiFePO₄ technology: Offers high energy efficiency and reduced sensitivity to partial charging.

• Compact design: Provides 256Wh of energy while weighing only 3.5kg (7.7lb).

• Expandable capacity: Multiple batteries can be connected in parallel.

• High efficiency: Approximately 92% round-trip energy efficiency.

• Long cycle life: Rated for 2,500 cycles at 80% depth of discharge (DoD) and 25°C.

• Built-in protection: Automatically limits charging or discharging when maximum operating ratings are exceeded.
