Description
CYR010400000
The Cyrix Battery Combiner is a microprocessor controlled heavy duty relay that automatically connects batteries in parallel when one of them has reached a pre-set voltage (indicating that the battery is being charged) and disconnects when the voltage decreases below float level (indicating that one or more batteries are being discharged). Cyrix Battery Combiners are an excellent replacement for diode isolators. The main feature is that there is virtually no voltage loss so that the output voltage of alternators or battery chargers does not need to be increased.

Replaced my old isolator with the Victron Cyrix‑i 12/24 V‑400 A Intelligent Battery Combiner and it’s been working smoothly ever since. It automatically links my starter and house batteries when the engine or alternator is running, and separates them when voltage drops—no manual switches or worries about draining one battery. The 400 A capacity handles heavy loads without overheating, and it mounts cleanly out of sight. No faults or unexpected cut-outs even after weeks of use. If you want seamless battery combining during charging and secure separation afterward, this Cyrix‑i does the job without fuss.
