Consider this device as a more affordable yet equally effective option for a top-of-the-line vehicle anti-theft system.

Unlike other battery disconnect switches, this unit’s design makes it impossible for carnappers to get away with your car.

The key is the product’s main advantage over other battery disconnect switches. You will never be able to operate this device without the key. The design gives it an additional security layer, giving you confidence that your RV will be there where you parked it.

I like the waterproof cover of this switch. Moisture and dust will never interfere with the connection inside the device. It is also resistant to corrosion, ensuring you have a system that works for you for many years.

This disconnect switch can preserve the energy of different battery systems because of its battery power optimization design. It even accommodates 24-volt and 48-volt battery systems.

When connected to a 12-volt battery, this disconnect switch allows 275 amps of continuous power, 1250 amps of momentary power, and 455 amps of intermittent power.

I admire the knob’s color-coded design. There is no way you will not know if the device is turned on or off.

Green always indicates a closed circuit connection, allowing you to use your appliances. Switch the device to Red, and you break the connection between your vehicle and the battery. The ingenious design makes it easy to manipulate the knob at night.

Installing this device in your motorhome is never an issue because it already comes with an RV battery disconnect switch wiring diagram.

4. Wirthco 20148 Battery Disconnect

While easy to operate, rotary disconnect switches are not precisely effortless to install. Most of them require some modification to the mounting surface. The Wirthco 20148 Battery Doctor RV battery box disconnect switch does not need any alteration. You can install this device directly into your battery terminal post in under five minutes.

Operating this device is as easy as pushing the lever into the opposite terminal to establish a connection. Do not worry about its safety because there is a plastic cap you can hold. You will never have to hold the brass lever when activating this best RV battery disconnect switch push pull mechanism.

Installing the device is a piece of cake. You remove the battery cable on the negative terminal and replace it with this device. You can then connect the negative cable to the switch’s opposite end. How simple can that be?

You know that this switch will last many years. Its solid metal construction gives you a feeling of security every time you pop your hood and establish or break the connection.

As mentioned, you only need to push the lever into the slot. Its lever is short enough never to touch your hood’s underside when in the OFF position. If in doubt, it is always easy to place a plastic or paper stopper between the lever and the post.

My only concern about this gadget is its lack of cover. You will have to be cautious when working under the hood. Its price is also about twice that of rotary battery disconnect switches. However, it is a small price for its effortless installation.

  • Very simple to operate
  • Effortless to install on battery terminal post
  • Low vertical operation for better clearance

5. Blue Sea Systems Battery Switch

The brand designed the M-Series Battery Switch for marine applications. However, its robust design also makes it ideal to use in motorhomes, campers, trailers, and even ordinary homes.

This RV battery switch can be an exceptional anti-theft device because of its inherent design. In its intended use, this product connects the battery to a boat’s motor. Breaking the connection between the boat’s engine and the battery will prevent anyone from using your boat. You can use the same principle in safeguarding your motorhome.

I like the snap-on rear panels of this product. It protects the wires and connections inside the gadget, ensuring its optimal functioning.

It also helps that the company decided to plate the copper studs with tin. Such a feature improves the unit’s electrical conductivity while also enhancing its corrosion resistance. It also has an IP66 rating for excellent weatherproofing.

This battery disconnect switch’s mounting design is exclusive to your instrument panel. You can mount this disconnect switch in any manner you choose.

Some people have voiced a concern about the small ON/OF print on the dial. It seems challenging for them to see the RV battery disconnect switch on or off when plugged in.

Still, memorizing the arrow position should simplify the process. The unit is OFF when the pointer is in the 12 o’clock position and ON when in the 3 o’clock position.

Another potential concern is its price. It is more than twice the price of a knob-type disconnect switch. If you look at its weatherproofing and durable construction, you know it is a fair price.

  • Ideal for connecting to onboard motors of marine vessels
  • Snap-on rear panels for better security and improved safety
  • Fine copper studs for maximum corrosion resistance and optimum conductivity
  • Multiple mounting options for exceptional versatility
  • IP66-rated design for marine use
  • ON/OFF markings seem a bit small for some people
  • More expensive than similar battery disconnect switches
While the Blue Systems M-Series is expensive, it remains a good choice for RV owners who need a more dependable switch to protect their battery and vehicle. Its weatherproofing is its strongest asset.

6. LotFancy Battery Switch

Another reliable RV battery cutoff switch you can install in your motorhome or any other electrical system is the LotFancy Battery Switch. It has the classic design of knob-type switches that makes for effortless operation.

The main draw of this device is its power isolation capability. It maintains your battery’s optimum charge when you store your RV in your garage. You can use it in your RV, car, boat, home, and any other application that requires a smoother power disconnection and isolation.

People love the switch’s case design that features removable panels for seamless cable connections. Even the rear panel is removable. You can secure the connections easily and quickly while ensuring protection against short circuits.

Operating this unit cannot be simpler. Checking for an RV battery disconnect switch not working is also straightforward because of its ON/OFF knob design. You will know if there is a connection in your circuit or not.

Remember your green traffic light to know that the system is working on transferring power from the battery to the rest of the vehicle.

This disconnect switch works with different batteries of varying voltage. The maximum voltage it can accommodate is 48 volts. A 12-volt battery connected to this device allows for a powerful cold cranking amps rating of 1250 amps, a five-minute intermittent power of 455 amps, and a one-hour continuous power of 275 amps.

It is worth mentioning that this product is a surface mount-only switch. This product is not for you if you want a more discreet switch. It is about three inches tall, so make sure to consider that in your decision. A few users noted the product’s inconsistent quality. It is a reliable disconnect switch, nevertheless.

  • Recommended for optimizing battery power
  • Removable side plates for better battery cable access

7. Nilight 90015A Battery Switch

The Nilight 90015A has an uncanny resemblance to the LotFancy motorhome battery disconnect switch. It makes you wonder if this product is unique to either brand or sourcing it elsewhere.

Speculations aside, this battery disconnect switch is a dependable tool for optimizing your battery’s charge. You can drive your motorhome in your garage for storage and leave it there for a few weeks. Battery drain will never be an issue as long as you have this battery disconnect switch in the right position.

Like many disconnect switches, this product is versatile. Most people use it in their motorhomes, while others use the device in their solar systems, wind turbines, and other clean energy applications. Others use the disconnect switch in their boats, cars, campers, trucks, and other vehicles.

It does not matter what kind of battery you connect this device to. You can have a 48-volt system or an ordinary 12-volt battery, and this disconnect switch will deliver its promise. Confidence to work on other things should be at its all-time high.

Unfortunately, one thing I dislike about this product is its limited mounting options. You can only secure this camper battery disconnect switch on a surface and never flushed in your panel. I also find its enclosure cheaply made. It looks thin and feels brittle. You have to be cautious when installing this gadget in your RV.

On the bright side, installation is straightforward. You do not need to modify your mounting panel, although you will have to drill holes for the bolts. The removable panels also make it easy to run the cables and connect them at the rear.

  • A good option for optimizing battery charge and preventing battery drain
  • Seamless design for effortless installation and operation
  • Multi-voltage battery compatibility for versatility
  • Removable rear and side plates for safety and ease of cable connections

8. Ampper Master Switch

Many people prefer a knife blade-type travel trailer battery disconnect switch for its hassle-free installation. You only need to remove your negative battery cable and replace it with the switch. You can then connect the battery cable to the device’s terminal post.

Unfortunately, some knife blade switches are beyond the means of the average RV owner. Not the Ampper Top Post Knife Blade Master Switch. This device gives you the convenience of installing a simple mechanism to prevent battery drain without spending too much.

Its simple design not only favors DIY installation. A few minutes and a bit of elbow grease are all you need to get this gadget working for you. Parasitic battery drain is history, and working under the hood should be safer with this device working its charm.

As long as your battery has a post, you should be able to mount this switch. You can place it in any vehicle or your deep cycle batteries for solar applications.

It also makes troubleshooting RV battery disconnect switch issues more straightforward. There is no housing to disassemble because you can see the connection right before your eyes. It is easy to check if the post is dirty that it is affecting the product’s conductivity.

This disconnect switch is not perfect. You know from its price tag that there are some compromises to its overall quality. First, the plastic bridge that supports the two contact towers looks weak. Second, the rivet that secures and swivels the knife is not heavy-duty. It is quite flimsy instead.

  • Ideal for power isolation and battery drain prevention
  • Durable and corrosion-resistant solid brass for improved safety
  • Simple design for hassle-free installation and operation
  • Versatile design for different applications
  • More affordable than similar knife blade-type disconnect switches
  • Fragile-looking plastic support bridge
  • Cheap-looking aluminum rivet
Despite having a few cheap components, the Ampper Top Post Knife Blade Master Switch remains a favorite among practical RV owners. Its worry-free installation and stellar performance make it a wise choice for those who want the best value for every cent they spend.

9. Ampper Am-CBS41 Disconnect Switch

Most disconnect switches on the market feature ABS plastic as their casing. They may be lightweight but are not as heavy-duty as solid aluminum housing. That is why the Ampper Am-CBS41 is the greatest choice for RV owners who want a sturdier device for their vehicles.

This heavy duty battery disconnect switch has an all-aluminum housing. It is strong enough to last many decades yet lightweight enough never to undermine your panel’s structural integrity. This combination is ideal for securing your battery and keeping it fully-charged for your next escapade.

Unlike other switches, this product has a straightforward design. You have a lever that you flip in the 5 o’clock position to break the circuit and the 7 o’clock position to establish a connection. It helps that the lever has a textured grip for ease of flipping. It is a standalone device that also works as a reliable partner for another switch.

You can install this device in your motorhome, car, truck, or boat. Suppose you have a wind turbine or a solar panel array. In that case, this device can also isolate the power to your battery to maintain its optimum charge. The safety it provides is exceptional in that you can keep your electrical system without worries.

Installing this battery disconnect switch requires drilling a hole to push the device through. It should not be an issue if you already have an existing ¾-inch hole in your panel.

My other concern is its low momentary current rating at only 440 amps. Other products have a momentary current rating that exceeds 1,000 amps. It is still sufficient for most 12-volt car battery systems.

  • Ideal for power isolation and battery power draw prevention
  • Heavy-duty aluminum housing for strength and durability
  • Simple design for straightforward operation
  • Universal design allows for different applications
  • Use as a standalone unit or in tandem with another switch

I like the product’s finish because it looks more polished than other knob-type battery disconnect switches. The knob is also larger, guaranteeing effortless operation. A simple twist of the knob already gives you a sense of security about its operation.

Two things may dissuade you from getting this RV dual battery disconnect switch. First, it is a few dollars more expensive than those with the same design. Without any substantial differentiation, this product can be a tough decision to make. Second, most products with the same design are less than three inches tall. This switch is a bit taller.

  • Recommended for securing electrical systems
  • Helps preventing unnecessary battery drain
  • Good for multiple applications, including marine, home, and automotive use
  • Effortless installation and operation
  • Good-quality finish despite being made of plastic

Mounting this device is straightforward with its heavy-duty screws and bolts. Its sturdy plastic construction also gives it stability once mounted.

Determining the RV battery disconnect switch on or off position is easy with this device. It has a bright green band that indicates the continuity of your electric circuit. A simple twist of its ergonomic knob to the red section automatically breaks the connection.

It is an effortless mechanism that can go a long way to making you feel more secure about your current electrical system setup.

You will not be able to fit a 5/16-inch power cable in these posts because it only accepts 3/8-inch crimps.

Another concern I have is the device’s height. It sticks out of the mounting surface like a bulky contraption. You may have to plan beforehand where to install this disconnect switch if you do not want it detracting from your panel’s aesthetics.

  • Compatible with 12V and 24V battery systems
  • Universal switch design for multiple applications
  • Durable and sturdy construction for more stable mounting
  • Easy to set up and operate
  • Ideal for minimizing battery drain

I also like the disconnect switch’s dustproof design. The removable rear panel also makes cable connections a breeze while ensuring a good seal to keep out dust and other particles. You can ensure optimal electrical conductivity by keeping unnecessary particles out.

You can install this kill switch and use it up to 10,000 times. No other brands can give you a more remarkable figure. Installing this device is perfect for any first-timer. It does not require any modification on your mounting surface. All you need are a few tools to drive and secure the mounting screws and bolts.

While this RV battery disconnect switch installation is straightforward, it does not offer that many mounting options. You can only install it on a surface but never flushed in your dashboard or instrument panel. Moreover, the ABS plastic casing looks fragile because of its thinner construction than other brands.

  • A dependable device for power isolation and security
  • Compatible with 12V to 48V battery systems
  • Reliable waterproofing and dust-proofing for improved safety
  • No mounting surface modification required
  • Lasts up to 10,000 switches

What to Look for When Buying an RV Battery Disconnect Switch


Buying a kill switch for an RV battery is often daunting for first-timers. The multitude of available products with nearly similar designs and specifications also does not help make choosing easy. However, you can make buying an RV disconnect switch hassle-free if you consider the following.

Principal Purpose

Always check the primary purpose of the battery disconnect switch. One of the principal goals of these devices is preventing battery drain. Theft prevention is another one. You should know that manufacturers design their products with a central purpose in mind.


Battery cutoff switches come in several types, including a knife blade, rotary, keyed, and remote switches.

Knife blade switches are the simplest you can have on your RV and easy to install, too. These switches have a brass lever that forms a bridge between two copper posts to establish or break a connection.

Rotary battery disconnect switches are the most common. You can install this device on your battery or the control panel. Some rotary types feature a lever for establishing or breaking a connection.

Keyed kill switches are modern adaptations of rotary devices. They operate on the same principle. However, you need a key to turn the device in its ON or OFF position.

The most modern of all battery disconnect switches are the remote disconnect switches. These devices are best for anti-theft purposes.


For absolute ease of installation, pick an RV battery shut off switch you can install directly on the battery post. If you want a more secure installation, a device that mounts in your instrument panel or dashboard is ideal. Such a device is perfect for anti-theft purposes.

Frequently Asked Questions (FAQs)


What are the most trusted RV battery disconnect switch brands?

Ampper is one of the most trusted battery disconnect switch brands for motorhomes, boats, cars, and other modern vehicles. You can check out the products of Zootliss, Kohree, WirthCo, Blue Sea Systems, Nilight, and Audew because these brands are trustworthy, too. You might also want to consider Loftfancy, AA Ignition, and ZYGMOLON.

Should a battery disconnect be on positive or negative?

On-battery disconnect switches always connect on the battery’s negative terminal. On the other hand, knob or rotary-type switches often require a connection to the battery’s positive terminal. Always check the manual if you are unsure.

Can a battery disconnect switch go bad?

Yes, a battery disconnect switch RV model can go bad. No switch of any kind will last forever. A battery disconnect switch failure can occur if its rated capacity is lower than the motorhome’s battery-dependent systems.

For example, if the RV requires 250 amps, a 200-amp switch will eventually fail.

It is also possible that the device’s contacts fail to mate correctly, leading to arcing. However, the most likely culprit for a failing battery disconnect switch is overheating due to an increased electrical current flow through the system.

How do you test a battery disconnect switch?

RV owners can test a 12V battery disconnect switch by switching the device to the “Storage” mode.

Grab a test light and secure it to where you connect your battery clamp. Disconnect the negative terminal on the battery as well.

Should RV battery disconnect on or off?

RV owners must keep their battery shut off switch for RV in the ON position at all times, except when they must leave their motorhomes for extended periods.

For example, it is always better to turn off the battery disconnect switch when storing the camper or travel trailer for the winter.

Doing so helps slow down the battery discharge rate. Batteries will still lose some electrical charge, but at a slower pace than if the disconnect switch is in the ON position. RV owners will not spend an extended time recharging their power bricks.

Should I disconnect my RV battery when plugged in?

You do not need to disconnect your RV battery when plugged in unless you will store your RV. Disconnecting the battery cuts power to your motorhome’s appliances, gadgets, and devices.

How do you install a battery disconnect switch on an RV?

Installing a battery shutoff device is a straightforward process.

On-battery disconnect switches require replacing the negative terminal cable with the disconnect switch. You can then connect the negative cable to the disconnect switch’s receiving post.
