Which Dual Battery System Do I Need? – Part 2: DC-DC Charger

PART 1 –

Hi Guys,

This is video number 2 in this 3 part series. In the first video, we discussed using a smart battery isolator for charging your dual battery system. Now we are going to delve into the next level up in dual batteries, the DC to DC charger or more commonly known by Redarc as a BCDC.

Like the Battery Isolator, the DC to DC Charger will always protect your starter battery, leaving you with enough power to start the car.

So let’s explore the reasons you would upgrade from a battery isolator to a DC to DC charger:

The first reason is – The majority of cars manufactured from 2006 onwards have a computer controlled alternator which thinks about fuel consumption and emissions not charging your auxiliary battery. So a DC to DC Charger is the first option for charging your dual battery systems in newer vehicles.

The second reason is – You may have multiple auxiliary batteries you need to charge. If you have one auxiliary battery to charge you would use a 25amp DC to DC charger. If you have two or three auxiliary batteries to charge you would use a 40amp DC to DC Charger

The third reason is – The isolator will only charge your AGM Batteries to 80%, however, due to the five stage charging program a DC to DC charger will charge them to 100%.

The fourth reason is – The DC-DC Charger has the ability to charge not only AGM batteries but also Calcium, Led Acid and now even lithium batteries to 100%.

The power is fed from the alternator to the starting battery to the DC to DC charger.

The DC to DC Charger like the isolator monitors the voltage of the starting battery, to see when your car is turned on and the alternator is charging.

The DC to DC charger is programmed with the chemistry of the auxiliary battery. This allows the power to then go from the DC to DC Charger to your auxiliary battery at the batteries optimum voltage, charging the battery to 100%.

The fifth reason is – As the DC to DC charger charges the battery to 100% your auxiliary battery will last longer before it needs to be replaced. Continuously under charging a battery will shorten its lifespan.

The sixth reason is – If you are driving around every day when you are on holiday’s with your motor running you will easily keep your auxiliary battery topped up enough to power your fridge and accessories, however, if you are parked up at a campsite for more than a couple of days you need another option to charge the auxiliary battery. The DC to DC Chargers come standard with an inbuilt M P P T solar regulator so you can plug a solar panel directly into it. As you can see we have a solar panel setup. The solar panel will run power through this cable into the battery charger and then into your auxiliary battery. So you can plug in a solar panel to keep your batteries topped up when the car isn’t running so you can stay in the one spot for weeks.

The seventh reason is – they feature fan-free cooling, which means no noise, it’s also a fully Sealed unit so it’s protected against dust, water and vibration which is great if you are doing trips like Cape York or the Simpson Desert

The eighth reason is – As long as the DC to DC charger is mounted next to the auxiliary battery it will overcome voltage drop caused by long cable runs. So the DC to DC charger is a great option for those mounting their auxiliary battery in the rear of the car or in a trailer.

There are stacks of brands of DC to DC chargers on the market like the Redarc BCDC range, Thunder Auto has this 20 amp DC to DC charger and CTEK is another leading brand that we stock.

The DC to DC charger allows you to charge from two inputs (alternator and solar). The next option is a battery management system or BMS, which will allow you to charge from a third input – 240 volts.

If you would like to have the option to charge from 240 volts check out the next video in this series explaining the Battery Management System.

SIZE MATTERS!! How does voltage drop in cable affect the amperage output of a DC/DC charger??

In this video we set up a cool demo to show you how the size of the electrical cable you run to your battery charger can affect how many amps you will get into your dual battery!
Size Matters – you will see that the heavy cable can let the dc/dc charger put about twice as much current into the battery than the smaller cable.
Any questions, drop them in the comments.

Cheers – Justin.


Honda Civic Hybrid Battery DC-DC Converter Replacement

In this video I will be showing were the Honda hybrid battery is and how to safely remove and replace the hybrid DC to DC converter. On this Honda hybrid, the DC converter is used to charge the accessory battery.

We had a battery light on in the dash of this Honda. Here is the video where I diagnosed this problem:
