Victron Energy Skylla-i Remote On/Off Cable

The Victron Energy Skylla-i Remote On/Off Cable Gives Your BMS Control Over Your Charger

The Victron Energy Skylla-i Remote On/Off Cable is a small but purposeful accessory that connects a Victron Skylla-i battery charger to a VE.Bus BMS. Once the two are linked, the VE.Bus BMS can disable the Skylla-i charger when the batteries are fully charged. For RVers, off-grid adventurers, homeowners with battery backup, and mobile business operators running a Skylla-i alongside a VE.Bus BMS, this Victron remote on/off cable lets the battery management system step in and say, "That's enough, thank you."

It will never be the star of your electrical layout, but it can be one of the most useful little parts in it. This cable is an accessory, not a charger or a battery management system. It does one job: it carries the on/off control connection between your VE.Bus BMS and your Skylla-i charger. Below, we cover what it does, where it fits, and what to confirm before you order.

Victron Energy Skylla-i Remote On/Off Cable Features

Skylla-i To VE.Bus BMS Connection So You Can Link Charging And Battery Management

Use this cable to connect a Skylla-i to a VE.Bus BMS. That single connection joins the charger and the battery management system, so charging can follow what the BMS is doing instead of depending on you to remember to switch something off.

Charger Disable At Full Charge For Hands-Off Control

When the Skylla-i is connected to the VE.Bus BMS with this cable, the BMS disables the Skylla-i charger once the batteries are fully charged. That means:

• Fewer manual steps in your charging routine
• A defined handoff between the charger and the battery management system
• A simple way to let battery status drive charger behavior

High Signal On, Low Signal Off Logic So You Can Plan Your Control Wiring

This cable is intended for on/off control based on the state of the source signal:

• Signal high: the Skylla-i is on
• Signal low or free floating: the Skylla-i is off

It helps to know this logic before you build or modify a system. If your control source behaves differently, confirm compatibility first.

Lightweight Accessory Format For Easy Order Planning

The listed weight is just 0.05 lbs, with listed dimensions of 0.39 × 9.06 × 8.27 inches. It is a small add-on that will not weigh down an order or a build. Before purchasing, confirm that it suits the routing distance between your Skylla-i and your VE.Bus BMS.

Real-World Applications

This cable only makes sense in systems that already use a Skylla-i charger and a VE.Bus BMS. In those systems, it can serve several kinds of Outbound Power customers:

• Homeowners: In a battery backup setup where a Skylla-i charges the bank and a VE.Bus BMS manages it, the cable lets the BMS shut off charging once the batteries are full.
• RVers: For a rig with a Skylla-i and VE.Bus BMS, it gives you one less charging task to manage between campsites.
• Off-grid adventurers: When you are far from help, an automated link between charger and BMS is a handy thing to have already wired in.
• Mobile businesses: If a work vehicle or mobile station relies on a battery bank, letting the BMS control the charger keeps charging in step with battery status.

Remote On/Off Control Compared To Manual Charger Management

Without a control connection between the BMS and the charger, the Skylla-i charges according to its own operation and whatever you do by hand. That can work, but it puts the "when do I stop charging?" question on you.

With the Skylla-i Remote On/Off Cable in place, the VE.Bus BMS can disable the charger when the batteries are fully charged. The cable does not replace a Skylla-i charger or a VE.Bus BMS, and it is not a standalone solution. It simply connects the two so they can work together. If you are still choosing components, treat the charger, the BMS, and this cable as parts of one system.

Is The Skylla-i Remote On/Off Cable Right For Your System

This cable is a good match for people who already own, or are building around, a Victron Skylla-i and a VE.Bus BMS.

This may be a good fit if:

• You want a Skylla-i connected to a VE.Bus BMS
• You want the BMS to disable the charger when the batteries are fully charged
• Your control source sends a high signal for on and a low or free floating signal for off
• You are adding to a Victron-based RV, off-grid, backup, or mobile power system

A few things to confirm before you buy:

• Your system uses both a Skylla-i charger and a VE.Bus BMS
• The cable is suitable for your exact Skylla-i model and layout
• The part number you need is ASS030550400

If you are unsure about wiring or compatibility, consult a qualified installer or the Outbound Power team before ordering.
