Battery isolators

Optimal division of charge current over multiple batteries

Onboard systems usually consist of two or more batteries that function independently when supplying the 12, 24 or 48 V consumers and require independent charging with reliable battery isolators and other peripheral equipment. 

Mastervolt offers several intelligent solutions:

  • Battery isolators that divide your charge current with a minimum energy loss.
  • The Charge Mate for connecting and/or disconnecting two batteries.
  • Robust manual switches for centrally turning off the power of the onboard network or starter circuit.
  • Battery Watch for monitoring the condition of your batteries (also usable as main switch).

Complete range for every system

  • BI battery isolators for conventional systems with an alternator or battery charger and two or three batteries.
  • Battery Mate battery isolators with a negligible voltage drop; most suitable for charging multiple batteries, possibly with various brands of alternators, even if their charge voltage cannot be adjusted. Ensures high efficiency and negligible energy loss.
  • Charge Mate for the parallel switching of two batteries while charging.
  • Battery Watch battery switch with protection against overvoltage and depletion of the battery.
  • Battery switches for switching on and off the consumers attached to the battery.

Robust and durable

Mastervolt’s completely corrosion-proof materials feature heat sinks made of aluminium alloy as well as electronic components (and, in the case of BI models, diode splitters) cast in synthetic materials.

Fast installation

The composite end plates feature connection lugs and solid bolt connections with nuts and locking rings to ensure easy installation.
