The Combiner 100 is a voltage-sensing relay (26.6 volts) which
connects two batteries together when either is receiving a charge. When
the charging ceases, the relay opens so that each battery operates
independently. Supplemental battery banks can be added by using an
additional combiner for each bank. You never have to worry about switching
to \"BOTH\" when your engine is running and forgetting to switch back to
save your starting battery from discharge when you stop.
This combiner is suitable for installations with alternators up to 100
amps with one battery in each bank.
