Go Power GP-ADV-BC-600 RV-C Advanced Interconnection Cable, 24 in

Go Power built the Advanced Lithium line to do more than store power. These batteries talk to each other and to the PowerTrak monitor over RV-C, and the GP-ADV-BC-600 is the cable that carries that conversation. It's a 24-inch (600 mm) data interconnection cable, and its whole job is to link one Advanced Lithium battery to the next so they report and behave as a single, coordinated bank instead of a pile of separate cells.

Here's the part a lot of people miss. A lithium bank isn't just a stack of batteries wired in parallel. To get accurate state of charge, per-battery health, and clean protection, the batteries need to share data, not just current. That's what RV-C does. It's a CAN-based communication standard used across RV electrical systems so the components actually understand each other. This cable is the physical link that puts your Advanced Lithium batteries onto that data network.

So what does that get you day to day? When your PowerTrak display shows state of charge, it's pulling real numbers from every battery in the chain, not guessing from voltage at a single point. If one battery runs warm or drifts out of balance, the system sees it. It also means the bank can protect itself as a unit, throttling or cutting in as needed rather than leaving one battery to fend for itself. That's the difference between a lithium bank you can trust on a long boondock and one you're second-guessing every morning before coffee.

The 24-inch length is the roomier of the two common options. It's the right pick when your batteries are mounted with a little space between them, when the run wraps around other gear in the bay, or when you just want some slack for a cleaner harness. If your batteries sit shoulder to shoulder, the shorter 16-inch (400 mm) version keeps things tidy. Either way, measure the distance between the communication ports before you order and give yourself a little room to work.

One thing worth being clear about. This is a data cable, not a power cable. It carries RV-C communication between batteries. It does not carry your charge and discharge current. You still need properly sized battery cables and lugs on the power side, rated for your inverter and charger loads. Think of the GP-ADV-BC-600 as the nervous system of the bank, not the muscle. Both have to be right, and they're separate runs.

Install is straightforward for anyone comfortable around a 12-volt system. The cable plugs into the RV-C communication ports on the batteries. Route it away from heat sources and sharp edges the way you'd treat any wiring run, secure it so it isn't flopping around on washboard roads, and you're done. Because it's Go Power's own cable for their own batteries, the connectors are keyed to the ports. No adapter guessing, no crimping, no trimming to length.

Who's this for? Anyone running or building a Go Power Advanced Lithium setup in a motorhome, fifth wheel, travel trailer, camper van, or overland rig. If you're adding a battery to an existing PowerTrak bank, you need a data link between the new unit and the rest of the chain, and this is that link in the 24-inch size. If you're starting from scratch, plan your data cable lengths right alongside your battery layout so the communication chain ends up as clean and considered as the power side of the install.

It's a small part with an outsized job. Get the communication chain right and the whole PowerTrak system does exactly what it's supposed to. You get honest, per-battery data, safer charging and discharging, and a lithium bank that runs predictable, trip after trip. That's cheap insurance for a setup that costs a lot more than the cable that ties it together.
