Havis battery isolators allow dual batteries to be charged from a single power source such as an alternator or battery charger. Due to the isolator’s ability to pass current in only one direction, your first battery can be discharged without draining power from the second battery.
With the VoltMaster battery equalizer, you can run 12 volt loads from your 24 volt battery system. Perfect for transit buses, private coaches, tour & charter buses, heavy trucks, off-highway equipment and alternative energy applications!
