This ensures fast and complete charging of your batteries without the need for additional settings in the alternator. These batteries require independent charging with reliable battery insulators or battery combiners. The system consists of two or more batteries that operate independently when powering 12 or 24 volt consumers. While BI battery splitters are standard diode splitters, Battery Mate technology is electronic and includes transistors. Battery Mate is suitable for charging multiple batteries, probably with different brands of alternator, even if the charging voltage is not adjustable. It can charge two or three batteries with very high efficiency without voltage drop. This battery is from the category of stores. Battery Mate is compatible with any type of alternator or battery charger in both older and newer systems. Since the voltage drop between the alternator and the battery is negligible, the dead battery performs far better than conventional battery insulators. Its components compensate for voltage drops and ensure that charging continues at the right voltage level, even with multiple battery banks.
