The Redarc BCDC dual-input battery charger allows for easy charging of a DC battery while you're on the move. Most battery chargers require that you plug into an AC outlet, but this DC-to-DC charger pulls power from your vehicle's start battery instead. The BCDC also has solar power capability so that you can keep your secondary battery charged while you're parked at a remote campsite. This means that you can go off the grid without worrying about being without power.
This charger connects directly to your battery, rather than pulling power from your vehicle via the trailer connector. This is to ensure that it's able to fully charge your auxiliary battery. A standard 7-way trailer connector is limited to 10 or 15 amps of current, which will not be able to fully restore a battery for use. But this charger can transfer up to 20 amps of current to both charge and maintain your auxiliary battery.
This charger can pull power from 2 different sources. The first input accepts charge from your vehicle's battery. The second input on this dual-input unit is designed to receive power from solar panels (sold separately). The built-in maximum power point tracking (MPPT) regulator on this unit ensures that the charger will get the most power possible from your panels at any given time. An MPPT regulator is able to determine the point at which your solar panels reach their maximum output. Then the regulator can simulate that load on the panels to effectively draw the most power possible. This type of regulator is more effective than traditional ones at gathering power from solar panels and at drawing power in low-light conditions.
The BCDC battery charger can be used to charge AGM, gel, standard lead acid, calcium, and Lithium ion (LiFePO4) batteries. An LED on the front panel of the unit will illuminate to show the charge profile, confirming that you've wired the charger correctly based on your auxiliary battery type. This LED will be solid while the unit is charging, and it will flash when the unit is in standby mode. Additional LEDs on this panel indicate where the charger is pulling power from, and what stage of the charging process the unit is in.
This smart charger completely and efficiently charges your auxiliary battery in 3 separate stages. This ensures that the battery reaches maximum capacity without being overcharged.
The first stage of the process, the boost stage, begins when you start up your vehicle. In this mode the charger will maintain a constant current to the auxiliary battery to quickly help it regain power.
Once the unit detects that your auxiliary battery is nearing its maximum charge, the charger will move into the absorption stage. In this stage it will slowly supply the needed current to safely reach 100-percent capacity on the auxiliary battery.
The final stage is known as the float stage. In this stage the unit monitors your auxiliary battery for drops in power and supplies the needed current to keep it fully charged. If a drop in power is detected, it will revert back to the first stage and begin the charging cycle over.
This unit can be mounted in a variety of places to best suit your application. Use the 4 mounting tabs to secure the unit in the cabin of your vehicle, along a chassis frame rail, in the engine compartment, or on your trailer. The charger should be mounted as close as possible to the auxiliary battery being charged to prevent current loss. The farther the current has to travel, the more amperage is lost. A larger diameter wire will allow more current to flow through it, which can offset the current loss that occurs with longer lengths of wire. As a result, it is recommended that you use a heavier gauge wire to cover longer distances.

Jeff Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this Redarc in-vehicle three-stage 24-volt battery charger. Now this will let you maintain the charge on your RV's battery, with this dual input, DC-to-DC smart charger. Application is for 24-volt vehicle systems with the standard fixed voltage alternators. And this is a dual input device, so the unit installs in your vehicle or trailer, and it pulls power from either your vehicles battery, or your solar panels.
Now, this is great for boondocking and dry camping. It is solar power capable. So it does have a built-in MPPT regulator to ensure most efficient power transfer possible in all conditions. It has the battery types that it supports, or the AGM, gel, standard lead acid, calcium, and even the lithium ion batteries. Battery capacity ranges 75 amp hours to 200 amp hours.
This is a DC-to-DC battery charger, which will draw power from your vehicle to provide power to an auxiliary battery on your trailer or RV. It's ideal for smaller battery banks rated less than 75 amp hours. Does have multi-stage charging algorithm, which ensures a nice, complete charge on your secondary battery, without overcharging. Offers a boost stage, which provides a constant charge, while monitoring auxiliary battery voltage. Has an absorption stage, which keeps the voltage stable to avoid overcharging, while bringing the battery up to 100% charge.
And it has a float stage, which maintains the charge on your auxiliary battery. Now the front panel right here, let me just zoom in so you can see it closer. But on this front panel, you can see it features six LEDs to display the charge profile, and the charge status. Now, this is a fully sealed construction. It's a fan-free operation to ensure durable performance under harsh conditions.
Has a fault recognition technology to prevent damage to the batteries from voltage spikes, overheating, and reverse polarity connection. Does offer a battery isolator function. Prevents the charger from pulling power from the start battery when the vehicle's off, and it gives you multiple mounting options, for a nice, convenient installation. Does come with this nice set of instructions that'll describe how this installs, and how it operates, but you can basically secure the unit in the cabin of your vehicle, along a chassis frame rail in the engine compartment, or even on your trailer. Specs on this unit. Maximum charging voltage 30.6 volts, output voltage 24 volts DC, output power 600 Watts, and the output current rating continuous is 20 amps, input current maximum 20 amps. And the last thing I want to do is just give you the overall dimensions on the unit itself. The width of it, one end to the other, is six inches. And this way, including the mounting, is going to be four and three quarter inches. And the overall height for the unit. The very top is one and a half inches tall. That should do it for the review on this Redarc in-vehicle three-stage 24-volt battery charger..
Great
Sharon was very helpful!
It's been a great product for me, it's completely autonomous, I just trust that my batteries are always charged!
Easy to buy, even easier and quick to receive the items bought.
Very good quality.
Product has worked as stated. 5 stars!
Great product, small form factor, solid construction.
Install took a little time. You will need a hydraulic connector press and then you will have to solder connectors. I ordered connectors off of the internet
As always another great product.This the only place I use when I need something for my camper.
Easy to install. Instruction were spot on. Not a single problem after a year of use. Definitely recommended. Worth the price.
What a difference this makes. Installing this means I have a fully charged battery when I get to camp
Have owned this charger for a year and has not failed me yet. It is built well and don’t foresee having any issues with it anytime soon. I’m glad I chose this brand.
Great product.
