About this product

✓ Bluetooth Monitoring✓ Smart Alternator Ready✓ 3-Stage Charging✓ Isolated
Smart DC-DC battery charger with Bluetooth monitoring — 18A output, 12V systems

Charges the leisure battery from the alternator whilst driving, whether your alternator is smart or not. This Victron DC-DC charger uses a 3-stage charging process and charges your leisure battery at the perfect voltage across a wide range of input voltages. Bluetooth allows you to see charge state and voltages easily. If you need modest power recovery whilst the engine is running, this is the ideal choice for safe, smart battery charging without overloading smaller batteries.

  • 18A output — suitable for single battery up to ~230Ah
  • Bluetooth monitoring via VictronConnect app (free, iOS/Android)
  • Smart alternator compatible (Euro 6 engines with start-stop)
  • Configurable for AGM, gel, or lithium batteries
  • 3-stage charging: bulk → absorption → float
  • Engine running detection built in

⚡ Key Features

01Smart Alternator Ready

Actively detects and follows smart alternator charging profiles (Euro 6 engines with start-stop). Unlike a VSR, it works reliably with modern vehicles (anything newer than c.2015).

02Bluetooth Monitoring

Monitor charge status, voltage in real-time via the free VictronConnect app on your phone. No separate display needed.

03Complete Charge Profile

3-stage charging (bulk → absorption → float) with configurable voltage settings for AGM, gel, or lithium. Your leisure battery gets the correct charge every time.
