The BATTERYLINK® Charger by Blue Sea Systems is a versatile and efficient battery charging solution for both onshore and offshore use. With its 20A multistage battery charger and integrated 170A Automatic Charging Relay (ACR), this charger allows you to charge two batteries simultaneously, ensuring reliable power supply for your marine applications.

  • Battery Temperature Compensation: Prolongs battery life by adjusting the charging voltage based on battery temperature.
  • Start isolation: Protects sensitive electronics from voltage sags and spikes.
  • Emergency parallel: Allows remote ability to jump-start by combining both batteries if the start battery is low.
