A complete kit to add a second (or third) battery to a car, boat, or RV. Built around the Cyrix-ct 12/24V 120A intelligent combiner, it charges your auxiliary battery from the engine's alternator whenever the engine is running, then isolates the start battery when charging stops - so a deep auxiliary load never leaves you unable to start.
The Cyrix-ct combines and isolates automatically with no voltage drop (unlike a diode isolator) and uses intelligent trend detection to avoid false switching. It also includes a Start Assist function to manually parallel the banks for 30 seconds in an emergency.
Features:
Cyrix-ct 12/24V 120A intelligent combiner (180A cranking) plus install hardware
Adds an isolated 2nd or 3rd battery to an engine charging system
Automatic combine/isolate with no voltage drop; auto-ranging 12/24V
