The Victron Energy Lithium SuperPack 25.6V/50Ah is specifically designed for 24 V-class electrical systems, combining 50 Ah capacity with 1280 Wh of nominal stored energy.

It offers the same nominal energy capacity as the 12.8 V / 100 Ah version, but in a higher-voltage configuration better suited to installations designed around a 24 V battery system.

Like the other SuperPack models, it incorporates an integrated Battery Management System and internal safety switch, eliminating the need for an external BMS. The battery automatically disconnects when over-discharge, over-charge or excessively high or low temperature conditions are detected. 

The battery can provide a maximum continuous discharge current of 50 A and a peak discharge current of 100 A for 10 seconds. Maximum continuous charge current is 50 A. Because this is the 25.6 V model, its recommended absorption charging voltage is 28.4–28.8 V, with a float voltage of 27 V and an end-of-discharge voltage of 20 V. 

The same LiFePO₄ advantages apply: operation at partial state of charge is practical, and the battery does not need to be fully charged after every cycle.

With 92% round-trip efficiency and a rated cycle life of 2500 cycles at 80% DoD / 25°C, the 25.6 V SuperPack is designed for dependable use in efficient 24 V installations.
