Need to safely connect two battery banks without draining one another? The Victron Energy Battery Combiner Kit is the smart, worry-free solution for any solar or mobile energy system where you need to manage multiple batteries—like a starter battery and a house (auxiliary) battery.
This compact, prewired kit uses Victron’s powerful Cyrix-ct intelligent relay, which automatically connects batteries in parallel when one reaches a preset voltage (indicating charge), and disconnects when voltage drops (indicating discharge). It allows for automatic and seamless battery combining — perfect for off-grid homes, RVs, boats, and vehicles running solar setups or multiple battery systems.
Automatic Voltage-Sensing Relay – No manual switching needed. Cyrix-ct makes the connection/disconnection based on real-time voltage.
Bidirectional Charging Support – Charge both banks no matter which one is receiving input (solar, alternator, or generator).
No Voltage Drops – Unlike diode-based combiners, Cyrix causes no loss in charging voltage.
Plug-and-Play Wiring – Pre-assembled kit with professional-grade cabling for quick installation.
Intelligent Monitoring – Prevents unwanted battery drainage by isolating weak or depleted batteries.
Failsafe Protection – System includes LED indicators and built-in protection against short circuits and overheating.
