What is a REDARC BCDC and what does it do?



The in-vehicle battery charger, or BCDC, keeps the auxiliary battery charged whilst driving, ensuring your secondary battery is charged to a proven 100% no matter its type or size.

The Dual Input range incorporates a MPPT solar regulator, allowing you to charge from solar panels and blankets, lessening the load on vehicle alternators.

The DC charger uses a multi-stage charging profile to ensure auxiliary batteries are charged to 100%, whereas a Smart Battery Isolator will only ‘top up’ the secondary battery as it
focuses on the state of charge of the primary battery.

In a dual battery setup where one battery is used as a starter battery to operate the vehicle and one as a secondary to run electrical devices, you need a BCDC. It offers greater flexibility for your dual battery setup, not only in terms of correct charging for your specific battery, but also suitability for different alternator types, installation location, and battery size.

Today we’re going to be taking a look at Redarc’s in vehicle BCDC battery charger. This charging system is going to be great for people who like to get off the grid. It uses your alternator to charge your auxiliary batteries. So while you’re on the go, you’re maintaining the charge and you’re ready to go, even if there’s no hook up site available to plug your camper in to get that energy. You’re getting it as you’re driving. Additionally, it has that place to put your solar panels, so you can use solar power to keep your batteries charged up.

So you can truly be self sufficient.Now many customers on our website compare this to a battery isolator, such as the one from Tow Ready. And while a battery isolator does allow you to charge your auxiliary batteries using your alternator and it keeps your start battery from discharging completely if you discharge your auxiliary batteries. This is going to do that plus so much more. It’s also going to allow you to use a solar panel and it has a smart unit inside to use that solar panel to charge these batteries. It’s going to be able to determine the most appropriate charge source, whether it be your solar panel or your alternator.Additionally, your alternator only puts out a set amount of voltage.

An isolator’s just going to use that to charge your batteries, which may not charge them to 100 percent. This is going to take that voltage from your alternator and it’s going to mold it, bringing it up or down as necessary to maintain 100 percent charge for your batteries.The alternator on your towed vehicle or in your RV maintains proper charge of your start battery. With this unit, you can harness that power from your alternator to charge your auxiliary batteries. What’s really nice about this unit is that it acts as an isolator to ensure that your starting battery is separate from your auxiliary batteries. What this means to you is, if you drain down your auxiliary batteries, it will not drain your start battery down.

So you can’t start the vehicle.And another feature that I really like about this charger is that it has the option to also use a solar panel. And while it’s not necessary, you could just run purely off your alternator. Having the solar panel up here will allow you to shut your vehicle off and maintain proper charge of your auxiliary batteries using the power of the sun. If your system deems it appropriate, it can use the solar panel in conjunction with the alternator to maintain proper charge, so you can ensure that they’re going to be ready to go when you get to your destination.But it does even more than that. What’s really nice about the smart chip that’s inside of it, is it can determine the type of batteries that you have installed for your auxiliary batteries.

And this is great because if you have lead acid batteries, those have different charge rates than are necessary to maintain proper charge and get the most life out of that battery. An improperly charged battery will have a premature wear and it won’t last nearly as long.There are four different profiles that you can set for your charge. The first three profiles will determine the maximum output voltage that your batteries can receive. This is going to be between 14.6, 15, and 15.3. You’ll want to refer to your battery’s manufacturer’s recommendations for the maximum output charge for your particular batteries. The fourth and final profile is for lithium batteries. You’ll want to refer to your instructions to determine how to connect to the orange wire that comes off your unit to achieve the appropriate profile.What this means is that you’re going to have longer life for your batteries, as well as maintain 100 percent charge. In most cases, if you we’re to just hook these batteries to your alternator, it’s just getting whatever voltage that your alternator was putting out for its normal charge process. And that may not be enough to charge the battery to 100 percent. In most cases, it’s not. And it may also charge the battery too much or too little at certain times, causing damage to the battery’s internal components. This will ensure that your battery’s charged properly and at 100 percent.What really makes this stand out is that the fourth profile is for lithium batteries. And lithium batteries are the way of the future. Lithium batteries can maintain a charge in cold weather climates much better than your AGM and lead acid batteries. So this is great if you plan on upgrading your batteries in the future.So if you’re like me and you n

Speaker 1: Today we’re going to take a look at the REDARC 24 volt 100 amp smart start battery isolator.Now this battery isolator will protect your start battery from auxiliary drain, and multiple battery setups. Transfers the charge from your start battery to your auxiliary battery, once the start battery gains charge from the alternator. The isolator function will stop power transfer from the charging battery if its voltage drops too low, which will prevent excessive discharge, and even a dead battery.The blue wire on this is an override wire, this allows for emergency starts and simple fault detection. Basically you can attach this wire to a switch, which we sell separately on our website, and that’s to manually reverse the charge and jumpstart a dead start battery. Or you can connect it to an LED that can be mounted in your cab for easy viewing of diagnostics.They do use silver contact points to ensure long life and corrosion resistance. It has a nice durable housing here to protect the sensitive electronics.

It’s a very compact design which allows for versatile installation.Overall dimension including the mounting bracket on the bottom is about three inches long. About two 1/4 inches wide. And about three and 1/4 inches tall. So you can mount this isolator in a nice convenient location near your start battery.Now we do carry six gauge cables, fuses and connectors we sell separately that you can use to install this. This part is made in Australia, application again is for vehicles with standard or temperature compensation alternators.

Maximum continuous current is 100 amps. Standby current is less than five milliamps, and the output connection for this is 24 volts DC.But that should do it for the review on the REDARC 24 volt 100 amp smart start battery isolator.

Speaker 1: Today, we’re going to take a look at the Redarc 24 Volt 100 Amp Smart Start Dual Sensing Battery Isolator. Now, this dual sensing battery isolator will connect in-line with two batteries, and transfer power in either direction. It can transfer charge from a start battery to an auxiliary battery once the start battery gains charge from the alternator. It can also pull power from the auxiliary battery that is connected to an outside power source to charge your start battery. The isolator function will stop the power transfer from the charging battery if the voltage drops too low so to help prevent excessive discharge in a dead battery.Now, the blue wire on this is an override wire. This can allow for emergency starts and simple fault detection.

You can attach this to a switch, which we sell separately on our website, to manually reverse the charge, and jumpstart a dead start battery, or you can connect it to an LED that can be mounted in your cab for easy viewing of the diagnostics.It does use silver contact points to ensure long life, corrosion resistance, has a nice durable housing to protect the sensitive electronics, and it is a compact design so it allows for reversible insulation. Overall dimensions on this is about three inches including the mounting bracket. About three inches, overall length. About two and a half inches wide, and about three and a half inches tall. That will allow you to mount the isolator in a convenient location near your start battery.Now, they do offer six gauge cables, fuses and connectors that we do sell separately that would work with this isolator.

This part is made in Australia. Application, this is for vehicles with standard or temperature compensating alternators. Maximum continuous current is 100 amps.

Full transcript: https://www.etrailer.com/tv-review-redarc-midi-fuse-kit-331-fk40.aspx
Speaker 1: Today we’ll be having a look at the Redarc 40 amp fuse kit for Redarc in-vehicle DC to DC battery chargers, part number 331-FK40.This fuse kit is a great solution when you need to fuse a power wire, such as this six gauge power wire. You may need to use this if you’re using a battery charger on a trailer, which is what we’re going to be using for, or if you’re using it for a wench or if you’re using it for a salt spreader on the back of a plow truck or whatever other application you’re using it with.In our particular case we’re using six gauge wire going into it. The terminals that come with it will crimp onto six gauge wire very nicely. This kit will come with two fuse holders and four fuses so you have two replacement fuses if you ever we’re happen to blow one.We also have four ring terminals so you can actually install both fuse holders appropriately.Now the reason you’re going to want this over other fuse options on the market is that this comes with everything you need in order to properly get a fuse setup on a wire, such as this six gauge wire. The reason you want to have fuse installed is because if you we’re to have a short circuit, you don’t have to worry about an electrical fire happening in your trailer, your vehicle, or damaging your piece of equipment that’s being powered by this. The fuse will blow, thus eliminating the risk of an electric fire or causing damage to your expensive devices.Now the fuses that come with this kit are rated up to 40 amps.

So if you we’re to have a draw over 40 amps, the fuse will then blow and then will protect the system. If you’re running less than 40 amps of current on your device, this will be a perfect solution for you.Inside of our fuse holder, you can find our 40 amp fuse. It’s easily replaceable with one of the included replacements if you we’re to need to replace it. You don’t have to worry about running to an auto parts store in order to get a replacement. You already have it so you’re safe for the future.Now that we’ve gone over some features, we’ll show you how to get it installed.As you can see here, we have a power wire in the engine compartment of our vehicle.

In order to hook this up to our battery, we need to make sure that we have a fuse to protect the circuit that this wire’s going to power.Now we’re going to cut off some insulation from all three ends of our wire. Just using a utility knife to this. If you have wire strippers that are big enough to this, that’s good. I don’t so I’m just using a utility knife.Now that we have a cut, we’ll pull off the end and we’ll twist the wire together nice and tight. We’ll do the same for the other two ends.Now we’ll take one of our ring terminals that comes with our kit, and we’ll stick it on the long end of our cable.

We’ll stick it down all the way and we’ll crimp it into place. We’re using a hydraulic crimper for this. These are readily available at most hardware stores.We did the same for one of the other ends of our short cable. Now on the other end of our short cable, since we’re using six gauge wire, we’re going to attach a six gauge ring terminal with a 3/8 of an inch diameter hole, part number SWC57016 on our website.We’ll use our same crimping tool to crimp that into place.Redarc does highly recommend that we solder .. I will go ahead and get some solder inside of there.Okay, now that our connection is soldered, we’ll have a great electrical connection that’s nice and solid.

We’ll take some heat shrink and we’ll cover up our solder joint and our cable. We’ll use a heat gun to shrink it down.We’ll repeat the same process as soldering and heat shrinking all of our connections from this point forward.Now we’ll take our fuse holder, remove the nuts. Take our provided 40 amp fuse. Place it over the studs and we’ll place our terminals over the studs and reinstall the nuts.Now we use an eight millimeter socket to tighten our nuts. Now we’ll take our cover and we’ll fold it over our connections and it’ll snap closed and lock into place.Now we’ll remove this nut on our positive battery post. Place a ring terminal over the stud and we’ll reinstall the nut.That completes our look at an installation of the Redarc 40 amp fuse kit for Redarc in-vehicle DC to DC battery chargers, part number 331-FK40.
