The three-output version, and for most overland builds it is the one to buy. One charger, plugged into shore power at home, keeps both the house bank and the vehicle's starter battery topped up.

Why the starter battery matters

A rig that sits for three weeks between trips will often start on a flat or weak cranking battery, especially with modern vehicles that never fully sleep. People discover this in the driveway on the morning they were leaving.

The three outputs are independent and isolated, so there is no current flowing between the batteries — the charger simply maintains each one. You are not relying on an isolator or a DC-DC to pass charge across while parked.

Smart distribution

The full 30A is shared across the outputs as needed. The house bank gets the bulk of it while it is low; once it is full, the charger keeps everything in float without over-charging anything.

Set it for your batteries

Bluetooth and VictronConnect for chemistry selection and charge profile. Storage mode for long periods plugged in. If your house bank is lithium and your starter is lead-acid, set the profile for the house bank chemistry — and ask us if you want to talk that through, because mixed chemistries on one charger need a moment's thought.
