Victron Energy Lithium SuperPack NG Battery (LiFePO4, Bluetooth, 12.8V, 25.6V & 51.2V)

The Victron Lithium SuperPack NG is a self-contained LiFePO4 battery built as a true drop-in replacement for lead-acid in marine, RV, and off-grid systems. Cells, a full battery management system, a battery monitor, and an internal safety switch are all integrated into one sealed IP65 case — install it, switch it on, and the battery looks after itself.

Bluetooth is built in: pair with the VictronConnect app for wireless setup, monitoring, and firmware updates, and use Instant Readout to check state of charge, temperature, warnings, and alarms at a glance without connecting. An On/Off push button and two status LEDs (Bluetooth and error) keep day-to-day operation simple.

A self-heating function keeps the cells above the safe charging threshold in the cold — in the default charger mode the connected charger powers the heater automatically below 0°C, so charging resumes the moment the cells are warm enough. A configurable discharge floor lets you reserve capacity, while the External Feedback Signal (EFS) provides a 250mA voltage signal that can drive an external alarm or trigger a charger-start signal for redundant system protection.

SuperPack NG delivers around 93% efficiency and a long cycle life — 2,500 cycles at 80% depth of discharge, 3,000 at 70%, and 5,000 at 50%. Batteries connect in parallel for unlimited capacity (total system current limited to what a single battery can safely interrupt); series connection is not supported. M8 threaded terminals; operating range −30°C to +60°C.

Range update (October 2026): Victron is adding two 5.1 kWh models — the 25.6V/200Ah NG and the 51.2V/100Ah NG — to the SuperPack NG family. Both are listed above and become available to order as soon as Victron releases them to US stock in October. Full charge/discharge ratings will be added when Victron publishes the datasheet rows.

Blue Marine is an authorized Victron Energy dealer — every SuperPack NG ships brand-new with Victron's 3-year lithium battery warranty, free shipping, and local pickup available.
