Onboard systems usually consist of two or more batteries that function independently when powering the 12, 24 or 48 V consumers. These batteries require independent charging with reliable battery isolators or battery combiners.
- Battery isolators that divide your charge current with a minimum energy loss.
- The Charge Mate for connecting and/or disconnecting two batteries.
- Battery Watch for monitoring the condition of your batteries (also usable as main switch).
Mastervolts BI battery isolators are based on conventional diode technology.
