Key Features
  • Fully configurable
  • Engine shutdown detection
  • Intelligent charge algorithms
  • Efficient cooling
  • Works with VictronConnect
  • Remote monitoring optional

Configurable charging
Precisely set the input and output current with simple controls. This helps protect alternators against overloading and to charge the service battery properly, especially in case of intelligent alternators.

Parallel to increase output current
An unlimited number of Smart BuckBoost devices can be connected in parallel. Making scaling the output current to match your system’s requirement easy.

Smart alternator compatibility
With its built-in engine shutdown detection, the Smart BuckBoost guarantees the charger only draws power when the engine is running. It also helps retrieving proper charge current from intelligent alternators as found in Euro 5 & Euro 6 engines.

Adaptive charge algorithm
The Smart BuckBoost includes customisable charging algorithms and 8 battery preset modes. For lead acid batteries, these settings ensure optimal absorption times for both shallow and deep discharges.

Complete electronic protection
The Smart BuckBoost comes equipped with comprehensive electronic protection against overload, short circuit and excessive temperatures. It will automatically reduce the output power when maximum product temperature is reached.

Low temperature shutdown & undervoltage protection
To prevent damage of lithium batteries, the charger will turn off automatically at low temperatures and when the input voltage drops below a user-configurable lockout value, protecting the starter battery from deep discharge.

Dust & waterproof
The Smart BuckBoost is designed to withstand dust and water pollution and has an IP65 classification.
