Battery Isolators
A battery isolator is used to separate the DC bus into multiple branches and only allow current flow in one direction in each branch. This supports simultaneously charging more than one battery from a single alternator or other power sources without connecting the batteries in parallel. Isolating the batteries prevents a weak or dead battery from draining charge from a strong battery. If a common diode-based isolator is used, lower system efficiencies result from the diode drop added to the circuit between the charging power source and the batteries.
