Mastervolt battery isolator diode very low voltage drop, battery combination device, optimized performance for alternators

Onboard systems typically consist of two or more batteries that operate independently of each other to power the 12 or 24 V loads. These batteries require independent charging with reliable battery isolators or battery combination devices.

Mastervolt offers you various intelligent solutions:

• Battery isolators that divide your charging current with minimal energy loss.
• Charge Mate for connecting/disconnecting two batteries.
• Battery Watch to monitor the condition of your batteries (can also be used as a main switch).

Battery Mate battery isolators with very low voltage drop

While BI battery isolators are conventional diode splitters, the Battery Mate's technology is electronic and uses MOSFETs (transistors). Its components compensate for the voltage drop and ensure that charging continues at the correct voltage level, even with multiple battery banks.

The Battery Mate is compatible with any type of alternator/battery charger, both in existing and new systems. Because the voltage drop between the alternator and the battery is negligible, the Battery Mate has significantly greater power than conventional battery isolators. This ensures fast and complete charging of your batteries without the need for any additional alternator modifications.

Charging two or three high-capacity batteries

The Battery Mate is the ideal solution for charging multiple batteries, possibly with other alternators whose charging voltage cannot be adjusted. It can charge two or three batteries with a high yield and without any voltage loss.

Models 1602/1603 are suitable for alternators with a maximum charging current of 160 amps, the Battery Mate 2503 is ideal for alternators with a maximum charging current of 250 amps.

Clear monitoring

Safety guaranteed: The Battery Mate's LED display shows whether the power input is active.

Robust and durable

Completely corrosion-resistant material with aluminum heat sink, the electronic components are encased in plastic.

Quick installation

The composite end plates are equipped with connecting cable lugs, and solid screw connections with nuts and locking rings guarantee easy installation.
