Typical Battery Combiner Diagram

Battery Combiners are essential for mariners and boat owners seeking a reliable, efficient way to manage their own batteries.

Battery Combiners connect two or more battery banks during charging, allowing a single power source to simultaneously charge multiple batteries. This ensures all your batteries stay ready for use. Many such combiners feature a manual override, enabling you to link battery banks for high-power demands or emergencies when the need arises.

When the charge source is turned off, Battery Combiners automatically disconnect the battery banks, preventing unnecessary power drain and optimizing battery health.

For mariners regularly hooking up to shore power, you may also consider adding a Galvanic Isolator to protect your electrical components from stray electric currents.
