The Victron Energy Lithium SuperPack 12.8V/20Ah is a compact LiFePO₄ battery designed for applications where low weight, efficient energy storage and simple installation are important. With a nominal energy capacity of 256 Wh, it is particularly suited to smaller 12 V systems where space is limited.

One of the major advantages of the SuperPack range is its integrated Battery Management System and safety switch. No separate external BMS is required. The internal protection system disconnects the battery when conditions such as over-discharge, over-charge or excessively low or high temperature occur. 

The battery provides a maximum continuous discharge current of 30 A and can supply 80 A for 10 seconds for short peak loads. Its maximum continuous charge current is 15 A. The recommended absorption charging voltage is 14.2–14.4 V, with a float voltage of 13.5 V. 

Thanks to LiFePO₄ technology, the battery does not need to be fully charged after every use. Victron states that partial-state-of-charge operation is not detrimental in the same way as with lead-acid batteries, making the SuperPack particularly practical in solar and mobile applications.
