The Victron Energy Cyrix-Li-ct 12/24V 230A Intelligent Li-ion Battery Combiner is on sale now at PowerHaven Outpost for $53.50 — down from $110. Buy online to pair a lead-acid starter battery with a LiFePO4 house battery safely, ideal for van, RV, and marine dual-battery owners.
How the Cyrix-Li-ct Works with a VE.Bus BMS
The Cyrix-Li-ct engages to parallel your batteries for charging, and disengages immediately when its control output becomes free-floating — signalling cell over-voltage or over-temperature — or when battery voltage drops below 13.2V. In a VE.Bus BMS system, the Cyrix receives the BMS control signal so the combiner opens before the lithium battery is stressed, protecting cells automatically.
Start Assist Function
A short negative pulse closes the relay for 30 seconds, letting you jump-start from the lithium bank when the starter battery is flat.

Protection & Deal Value
A built-in transient voltage suppressor limits voltage spikes when the Cyrix suddenly disengages. At $53.50 vs the $110 compare-at price, you save $56.50 — plus 12% more with coupon code OUTPOST12 and free shipping on orders over $45.
Cyrix-Li-ct vs Cyrix-Li-Charge
The Cyrix-Li-ct is a bidirectional 230A combiner with VE.Bus BMS control; the Cyrix-Li-Charge is a unidirectional charge relay. Choose the Li-ct for bidirectional paralleling and start-assist.
How to Reset
The Cyrix resets automatically once fault conditions clear and the control signal is restored — no manual reset is needed.
