Victron's latest marine products for an electric boat (2026) — and how they map to your spec

If you've run the configurator, you have a motor power, a pack size in kWh, a DC current and a charge-time estimate. The natural next question is which Victron products those numbers turn into. This page maps each figure to a current Victron part, using the ratings in Victron's own datasheets, and ends with one boat's figures turned into a parts list.

How the configurator output maps to Victron's range

One fork comes first. Victron's battery system — Lithium NG batteries with a Lynx Smart BMS NG — tops out at 48 V. A larger propulsion pack, or any 96 V system, is built from other modules or cells with their own BMS. Victron's chargers, MPPTs and monitoring can still run the rest of the boat; only the battery and BMS change. The BMS guide and the battery bank guide cover that route.

Lithium NG and the Lynx Smart BMS NG

Each Lithium NG 51.2 V battery stores 5.12 kWh (100 Ah) and can deliver 100 A continuously, or 200 A for 10 seconds. Up to 25 can be paralleled in a 48 V system. Divide your pack kWh by 5.12 to get the battery count.

The Lynx Smart BMS NG works only with Lithium NG batteries. It combines a contactor, pre-charge and battery monitor in a Lynx busbar module, and through a GX device it sets the charge and discharge limits that Victron chargers follow (DVCC). It comes rated 500 A or 1000 A continuous.

Check two current limits against your configurator's DC figures:

1. The batteries: number of batteries × 100 A must exceed your continuous DC current, and × 200 A must exceed the 10-second peak.
2. The BMS: its 500 A or 1000 A rating must exceed your continuous DC current.

Take current from the configurator, not from power ÷ 48 V. A 15 kW motor at 48 V needs 521 A design continuous current, because the configurator takes the pack's minimum voltage and adds headroom. That's past the 500 A BMS, and at that size the configurator moves the boat to 96 V, where this battery system doesn't go. See 48 V vs 96 V.

MultiPlus-II and Quattro-II — shore charging and AC

The configurator's charge time depends on charger current. Victron's 48 V inverter/chargers, from their datasheets:

The Quattro-II has two AC inputs, such as shore and generator, with automatic switching between them. The MultiPlus-II has one. Up to six units can run in parallel, and three of the same model can be set up for three-phase output. The 8k, 10k and 15k MultiPlus-II models can be paralleled only with an external AC transfer switch.

To size: charger amps ≈ kWh to refill ÷ hours available ÷ battery voltage. Refilling 20–80% of a 25.6 kWh bank (15.4 kWh) in 9 hours needs about 37 A at 51.2 V allowing for 90% efficiency, so a 48/5000 (70 A) does it comfortably. Refilling 24 kWh in 4 hours needs about 130 A: a 48/10000 (140 A), or two 48/5000s in parallel.

For three-phase arrays, see the single vs three-phase Victron guide and the three-phase configuration walkthrough.

Solar controllers

Not every Victron MPPT charges a 48 V battery. In the SmartSolar range, the 75/xx models and the 100/30 and 100/50 are 12/24 V only. The 100/20 in its 48 V version, and all the 150 V and 250 V models, support 48 V. The solar guide turns your daily energy target into panel area and controller size.

Orion converters — the 12 V house supply

Almost every electric boat still has a 12 V bus for electronics and lighting. Feeding it from the propulsion bank through a DC-DC converter saves keeping a separate battery charged. Victron lists an Orion-Tr Smart 48/12-30 (isolated), and a non-Smart isolated Orion-Tr 48/12-20. Size it to your 12 V continuous load plus a margin; the configurator doesn't size house loads, so add these from your own list.

The Orion XS, which Victron rates at up to 98.5% charging efficiency, comes only as 12/12 models (50 A and 70 A), so it isn't a 48 V option.

Cerbo GX — coordination and monitoring

The Cerbo GX coordinates the inverter/chargers, MPPTs and BMS so they follow one set of limits, and shows the system on a GX Touch screen and Victron's VRM portal. The current versions are the MK2 and MK3. If your boat combines VE.Can devices with a battery that uses BMS-Can at 500 kbit/s, you need the MK2's or MK3's second CAN bus. See Cerbo GX, MK2 and MK3 compared. The MK3 has the same ports and a faster processor; it's worth choosing if you'll run Node-RED or Signal K on the Cerbo, as Cerbo GX MK3 vs MK2 explains.

With a Lynx Smart BMS NG you don't need a separate battery shunt, because the BMS includes the battery monitor. With a third-party BMS, a SmartShunt rated above your peak current does that job.

Worked example: the 35-footer

From the configurator's 35 ft sailboat profile: 8 kW motor, 48 V, 25.6 kWh pack, 222 A DC at full power and 278 A design continuous, 513 A for 10 seconds.

Every line traces back to a configurator figure, which is the point: the spec sheet should make the parts list obvious.

Before you buy

Victron revises ratings, model names and availability, and regional model numbers differ. Confirm each part against the current datasheet, especially the BMS and battery current ratings against your peak DC figure.
