The two big SuperPack NGs are finally here. Victron Energy said on 2 November 2026 that its 25.6V/200Ah and 51.2V/100Ah models are “now available”. They aren’t new to us, though. Both part numbers were already in the SuperPack NG datasheet published alongside the range’s 4 February 2026 launch, flagged “Product launch after Q1 2026”. A later stock update added to that launch post said they were “planned to follow in Q2”. November is well past Q2, so by our count they’re about four months late.

- BAT548110740, Lithium SuperPack 51.2V/100Ah NG
They join the 12.8V/100Ah, 12.8V/200Ah and 25.6V/100Ah models that launched in February, so the range now covers 12V, 24V and 48V systems.
For boat owners, the appeal of the SuperPack NG is that it’s a self-contained LiFePO4 drop-in for lead-acid. Because the battery management system sits inside the case, you don’t need a separate BMS. Victron also lists IP65 protection, self-heating for charging down to -30 °C, discharge up to 2C, a bi-directional e-switch that cuts charge or discharge independently, and an on/off button for laying up the boat (storage for up to a year without recharging, starting above 50% charge). In addition, there’s a 3/4" threaded safety vent you can pipe out of an enclosed engine room or battery locker, as well as monitoring through VictronConnect over Bluetooth.
Our take: it’s mostly a drop-in replacement for system and house battery banks. For boats, the 24V model is the most useful, because very few boats take 48V. The limit, however, is that the batteries only support parallel operation and not series. Victron’s datasheet is blunt about it: “Series configuration: No”. Parallel banks, by contrast, can grow without a unit limit, as long as total system current stays within the 800 A that a single battery can safely interrupt. Then there’s the size. The 12.8V/100Ah measures 273 × 173 × 173 mm, whereas Victron’s 106Ah Lead Carbon is 410 × 172 × 225 mm, and even the closest lead model, the 100Ah AGM Super Cycle, is 260 × 168 × 215 mm. Likewise, the 12.8V/200Ah is 466 × 198 × 173 mm, while the 160Ah Lead Carbon and 230Ah AGM Super Cycle share a 532 × 207 × 226 mm case and the 220Ah AGM and GEL Deep Cycle measure 522 × 238 × 240 mm. Meanwhile, the new 24V/200Ah and 48V/100Ah share an 871 × 198 × 173 mm case, and Victron lists no 24V lead battery to compare. So why Victron’s “drop-in replacements” aren’t the same sizes as Victron’s own lead batteries, one can only wonder.
