What is Victron Cyrix?

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 …

What is a battery combiner?

Battery Combiners allow two and sometimes, more than two, battery banks to be automatically combined (connected) together during charging allowing a single charge source to charge multiple battery banks. Combiners automatically disconnect the battery banks once the charge source is removed or turned off.

How does a battery to battery charger work?

Inductive battery chargers use electromagnetic induction to charge batteries. A charging station sends electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metal contacts between the charger and the battery.

Do I need a battery combiner?

If you have multiple battery banks onboard and require redundancy then a battery isolator will ensure that no single battery drains the other batteries. If you have similar sized battery banks and only one charging source with no excessive draws then a battery combiner is the way to go.

How do banks charge multiple batteries?

An example method of charging batteries in parallel is to use one branch of the parallel circuit to charge each battery with a single charger. Connect the positive output of the charger to the positive terminal of the first battery, and connect that positive terminal to the positive terminal of the second battery.

Do you need an isolator for dual battery?

The two batteries – your vehicle’s starting battery and your auxiliary battery – are two separate, isolated systems. For correct operation, a dual battery setup needs a battery isolator.

What does a smart battery isolator do?

When batteries reach 12.7V, the Smart Battery Isolator senses it, opens the solenoid relay to separate the battery banks, and turns off the status light. This protects the starting battery while allowing the auxiliary battery to continue to power the auxiliary loads.

How do you tell if a battery charger is working properly?

Running a test on your battery charger is an easy process.

1. Plug in your charger to an electrical outlet.
2. Turn on your voltmeter unit.
3. Take a battery or battery pack that’s compatible to your battery charger.
4. Check the readout on the voltmeter and see where the pointer is indicating to.

Can you charge two batteries one alternator?

You can run two batteries on the same alternator. The alternator registers these two batteries as a single large battery and charges them the same. The batteries self-regulate the amount of current they take as they charge. This means that a single alternator is effective for multiple batteries.
