What Exactly is a Can-Am Outlander Dual Battery Kit?
Think of it as power insurance for your ATV. At its core, a dual battery kit adds a second, auxiliary battery to your machine and a smart device to manage them both. It’s not just about having a spare; it’s about having an intelligent power management system.
The system isolates your main starting battery from your “house” or accessory battery. This means you can run your winch, sound system, GPS, and LED lights off the auxiliary battery without ever draining the one you need to start the engine and get home.
The Heart of the System: The Battery Isolator
The magic component is the battery isolator or smart relay. This device acts like a one-way gate for electricity. When your engine is running and the alternator is charging, the isolator connects both batteries so they can charge up together.
But as soon as you turn the engine off, the isolator senses the voltage drop and automatically disconnects the main starting battery. This completely protects it, leaving your auxiliary battery to power all your gear. It’s a simple but brilliant piece of tech.
Primary vs. Auxiliary: Understanding the Two-Battery Setup
It’s crucial to understand the roles of each battery in your new setup. This simple concept is key to getting the most from your kit.
- Primary Battery: This is your original factory battery. Its sole job is now to start the engine. It’s kept fully charged and isolated from your power-hungry accessories.
- Auxiliary Battery: This is the new battery you install. It powers everything else: your winch, lights, stereo, heated grips, and any other electrical mods. You can drain it completely, and you’ll still be able to start your Outlander without a problem.
The Unbeatable Benefits of a Can-Am Outlander Dual Battery Kit
Still on the fence? Let’s look at the real-world advantages you get on the trail. This isn’t just a “nice-to-have” mod; for serious riders, it’s essential.
- Rock-Solid Starting Reliability: This is the number one reason. Never again worry about a dead battery leaving you stranded. Your starting battery is always protected and ready to go.
- Run Accessories with Confidence: Want to run your camp lights all night or blast tunes while you’re stopped for a break? Go for it. You won’t be risking your ride home.
- Massive Winching Power: A winch is one of the most demanding accessories on your electrical system. A dual battery setup provides the deep-cycle power needed for long, heavy pulls without killing your engine or stalling the winch.
- Extended Battery Life: By splitting the workload, you reduce the strain on both batteries. Your starting battery isn’t being deep-cycled, and your auxiliary battery is designed for it, leading to a longer lifespan for both.
- Self-Jump-Starting Capability: Some advanced kits come with a “boost” or “combine” feature. If your main battery ever does fail for some reason, you can press a button to temporarily link both batteries and jump-start yourself.
Choosing the Right Dual Battery Kit for Your Outlander
Not all kits are created equal. Making the right choice upfront will save you headaches down the road. Here’s what to look for in a quality can am outlander dual battery kit.
Solenoid vs. Solid-State Isolators: What’s the Difference?
You’ll mainly see two types of isolators on the market. Both do the same job, but they go about it differently.
A solenoid-based isolator is a heavy-duty mechanical relay. It’s proven technology, reliable, and generally more affordable. You’ll hear a distinct “clunk” when it engages or disengages.
A solid-state isolator (often called a Smart Battery Isolator or Voltage Sensitive Relay – VSR) has no moving parts. It uses electronics to sense voltage and is generally more durable, weatherproof, and efficient, but it comes at a higher price point. For the rough-and-tumble world of off-roading, a sealed, solid-state unit is often the superior choice.
Matching Batteries: The Key to Longevity
Here’s one of the most important can am outlander dual battery kit tips: for best performance and longevity, your primary and auxiliary batteries should be the same type and chemistry. If your main battery is a lead-acid AGM (Absorbed Glass Mat), your second battery should also be an AGM.
Mixing battery types (like a standard lead-acid with a lithium) can lead to improper charging and a shorter lifespan for both. If you’re upgrading, it’s a great time to install two brand new, identical AGM batteries for a perfectly balanced system.
How to Install a Can-Am Outlander Dual Battery Kit: A Step-by-Step Guide
Alright, let’s get our hands dirty. This installation is well within the reach of a careful DIYer with basic tools. Remember: safety first! Always work in a well-ventilated area and wear safety glasses. This can am outlander dual battery kit guide will walk you through the process.
Tools & Materials Needed:
- Your dual battery kit (isolator, wiring, connectors)
- A quality auxiliary battery
- Socket and wrench set (metric)
- Wire cutters/strippers/crimpers
- Zip ties
- Drill and bits (if needed for mounting)
- A digital multimeter
- Safety First: Disconnect the Main Battery. Before you touch a single wire, locate your main battery and disconnect the negative (-) terminal first, then the positive (+) terminal. This prevents any accidental shorts.
- Find a Home for Your Second Battery. This is the biggest challenge on a compact ATV. Many kits are designed for specific locations, often under the seat or in a storage compartment. Find a secure spot where the battery won’t vibrate excessively or be exposed to extreme heat.
- Mount the Battery Securely. Use the mounting tray or bracket that came with your kit. A loose battery is a dangerous battery. Ensure it’s strapped down tight and the terminals can’t contact any metal frame parts.
- Mount the Isolator. Find a clean, dry spot for the isolator, usually close to the main battery. Keep it away from high-heat areas like the exhaust. Secure it firmly with screws or bolts.
-
Run the Main Wires. Your kit will have heavy-gauge red and black cables.
- Connect the first red cable from the positive (+) terminal of your main battery to the corresponding post on the isolator.
- Connect the second red cable from the other main post on the isolator to the positive (+) terminal of your auxiliary battery.
- Connect the main black ground cable from the negative (-) terminal of your auxiliary battery to a solid, unpainted spot on the ATV’s frame. A good ground is critical!
- Connect the Isolator’s Ground. The isolator itself will have a small black ground wire. Connect this to the same frame ground point or another suitable chassis ground.
- Tidy Up and Secure Your Wiring. This is a pro step that many people skip. Use zip ties to neatly secure all your new wiring. Route cables away from sharp edges, moving parts (like suspension or steering), and hot exhaust components. A clean install is a reliable install.
- Reconnect the Main Battery. Now, do the reverse of step one. Connect the positive (+) terminal first, then the negative (-) terminal. Tighten them securely.
- Test the System. Time for the moment of truth! Use your multimeter. With the engine off, check the voltage of each battery separately. They should read around 12.4-12.7 volts. Now, start the engine. The voltage on both batteries should jump to the charging voltage, typically between 13.5 and 14.4 volts. This confirms your isolator is working correctly and charging both batteries.
Common Problems with Can-Am Outlander Dual Battery Kit Setups (And How to Fix Them)
Even with a great install, you can run into issues. Here are a few common problems and how to troubleshoot them.
Problem: My auxiliary battery isn’t charging.
Solution: This is almost always a bad ground connection. Double-check that your main ground from the auxiliary battery and the small ground from the isolator are connected to clean, bare metal on the frame. Also, use your multimeter to confirm the isolator is receiving charging voltage from the main battery when the engine is running.
Problem: My main battery is still dying.
Solution: This means the isolator isn’t disconnecting when the engine is off. First, check that the isolator is wired correctly. If it is, the isolator itself may have failed in the “closed” or “connected” position. A quality VSR is the best way to prevent this.
Long-Term Care and Best Practices for Your Dual Battery System
To get years of reliable service, you need to follow a few best practices. This can am outlander dual battery kit care guide is simple to follow.
A more sustainable can am outlander dual battery kit setup is one that lasts. Regular maintenance prevents premature failure and waste. Periodically check that all connections are tight and free of corrosion. A wire brush and some dielectric grease on the terminals work wonders.
If you store your Outlander for long periods, connect both batteries to a multi-bank smart trickle charger. This is one of the most crucial can am outlander dual battery kit best practices to ensure they are healthy and ready for your next ride. A well-maintained system is an eco-friendly can am outlander dual battery kit because it maximizes battery lifespan, reducing the need for replacements.
Frequently Asked Questions About Can-Am Outlander Dual Battery Kits
Can I use two different types or sizes of batteries?
It’s highly recommended to use two batteries of the same type (e.g., both AGM) and similar age/capacity. Mixing types can cause one battery to overcharge while the other undercharges, dramatically shortening the life of both.
Will installing a dual battery kit void my Can-Am warranty?
Generally, adding aftermarket accessories does not automatically void your entire vehicle warranty. However, if an electrical failure occurs and the dealer can prove it was caused directly by your aftermarket installation, they could deny a warranty claim for that specific failure. A clean, professional-style installation greatly reduces this risk.
How do I know if my isolator is working correctly?
The easiest way is with a multimeter. When the engine is off, the voltage at each battery should be independent. When you start the engine, the voltage at the auxiliary battery should rise to match the charging voltage of the main battery (usually 13.5V+). This shows the isolator has connected them for charging.
What size auxiliary battery should I get?
This depends on your accessory load. Look at the amp-hour (Ah) rating. For most users running a winch and some lights, a second battery matching the stock size (around 30Ah) is plenty. If you have a massive stereo system or run lots of equipment with the engine off, you may want to find space for a larger deep-cycle battery.
Installing a dual battery kit is a true game-changer for any serious Outlander owner. It transforms your machine from a recreational vehicle into a reliable, self-sufficient exploration tool. You gain the freedom to use your gear without fear and the confidence to push deeper into the backcountry, knowing you have the power to get back home.
Take your time with the install, keep it clean, and follow these steps. The peace of mind you’ll have on your next ride is more than worth the effort. Now get out there and explore with confidence! Stay safe and power on!
