Redarc DC to DC charge Systems

Aug 052019

Not so common in the UK but used extensively by Australian 4WD drive enthusiasts is the REDARC range of DC to DC chargers. From the little DC to DC and MPPT charger only to the all singing & dancing DC to DC, Mains 240V charging and MPPT solar.



The REDARC BCDC1240D In-vehicle Battery Charger is the next generation in REDARC's DC to DC charging technology, with additional features that make it the most advanced dual battery charger on the market.

Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1240D will charge from both solar and the alternator simultaneously. With built-in 'Green Power Priority' it will select solar charging first, meaning less load on the alternator.

Suitable for 12 or 24-volt vehicle systems, the unit will also work with either standard or variable/smart alternators.

The BCDC1240D also comes with patented charging profiles, including a lithium charging profile. The 'Dual' input range will continue to charge all other types of batteries including AGM, GEL, standard lead acid and calcium.

As a guide, the BCDC1240D is used for battery bank sizes over 200AH. For smaller batteries of 75-200AH REDARC recommends the BCDC1225D.


Proven and Tested

The award-winning technology in the BCDC has been independently verified and tested to ensure battery life is maximised, charging your battery to a proven 100%.

Built in Australia and tested for our unique conditions, the DC to DC battery charger will work in the extreme heat of the Simpson Desert, up to 80°C and can handle deep water crossings at Cape York – water, dust and vibration are no match for this charger.

If you’re heading out into the bush and want to get there and back again safely – you can trust REDARC.

The Manager30 is a complete battery management system for charging auxiliary batteries used in recreational automotive and marine applications. The dual battery system incorporates AC, DC and solar inputs to achieve the best charge for an auxiliary battery.

Developed with ease of installation in mind, The Manager30 is compatible with all vehicles and alternator systems including variable voltage alternators.

Whether you’re charging Lead Acid, Gel, Calcium, AGM or Lithium Iron Phosphate batteries, The Manager30 represents a complete DC to DC charging and maintenance solution. If you’re charging one auxiliary battery or more, The Manager30 will ensure they’re always fully charged, providing peace of mind when battery charge provides the power source for the comforts of home whilst travelling around Australia.

The Manager30 operates like 6 separate products, it charges an auxiliary battery from the vehicle while on the move, it’s a 240 volt charger, a solar regulator, a battery isolator, a load disconnect controller, all with a remote battery monitor, making it market leading.


Charging lithium batteries
Lithium batteries have improved storage capacity relative to size and weight. They do however require specific charging conditions in order to operate correctly and the battery itself must have an in-built cell management system. REDARC have designed a charging profile within The Manager30 to complement these in-built systems.


Green power priority
The Manager30 is designed to charge an auxiliary battery from multiple sources simultaneously. If 12 volt solar power is available, solar power will be used before topping up the output charging current from another source mains (if available) or DC vehicle power when on the move.


MPPT solar regulator
The built-in Maximum Power Point Tracking (MPPT) solar regulator allows The Manager30 to deliver the maximum amount of power from portable solar panels, even during low light conditions.


Remote monitor
Designed to show you auxiliary battery information and charge status. You can customise how your battery is charged and monitor where the charge is coming from. A user-friendly, graphical display monitor lets you know what’s going on, keeping you in control at all times.

Water Filters & Cleaning

Aug 052019

People often ask what I run in my on board water system. So here it is below. This is for the normal system used for cooking and boiling for brews etc. For water I want to drink I decant it into my Lifesaver Jerry can.


First is a 10" water filter housing with a pleated 0.5 micron sediment filter fitted, this removes particles and free floating debris etc.



Second I use a Whale Silverised carbon inline filter to remove smells and taste. This can be left in situ and changed once per season. This removes chlorine and smells from the system.


Silverised carbon filter designed to remove unpleasant tastes and smells from your water supply.

Simple to install and maintenance free.

Removes unpleasant tastes and smells from water from in board tanks
Simple installation using clips supplied
Maintenance-free design
Can be mounted vertically or horizontally
Suitable for use with Whale Quick Connect/ flexible pipework
Lasts one full season or 4500 litres
Installed in the freshwater plumbing pipework - usually under the sink
Sesign for 12mm pipe fittings


The Water Tank is a 30 litre Axxis Products clear tank and about the cheapest large opening tank I could find.



The pumping is done via a Surflow on demand pump



The water is then delivered to the back of the truck to a Bullfinch water outlet & trigger shower head 



Cleaning is done frequently using Puriclean and lots of fresh water, So far this system has never let me down


All water tanks, pipes and taps become contaminated with dirt, stains, bacteria and algae. Puriclean provides a simple, effective method of cleaning and purifying the water system on caravans, motorhomes and boats.

Puriclean is non-toxic and non-caustic and has no taste or smell and does not foam or harm any components in your water system.

To use fill your water tank with a Puriclean solution and run through your pipes. Leave to soak for up to 12 hours and then drain and rinse the system. Your water system will then be clean and ready to be fuilled with fresh water.

Periodic use will ensure a clean healthy system for water storage.

100g Cleans tanks up to 90 litres
400g Cleans tanks up to 270 litres
4 kg Cleans tanks up to 2500 litres
Puriclean can also be used to remove stains and clean many domestic items such as glassware, plastic tableware, tea and coffee pots, china, cutlery, stainless steel and vacumm flasks.

Plastor Storage Boxes
