Rugged under bonnet 12V 40A DC to DC battery charger. Lithium Compatible.

The REDARC BCDC1240D under bonnet Battery Charger is a 12V 40A DC to DC battery charger, capable of high performance in engine bay installations, potted to survive and thrive against heat, water and dust. 

Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1240D Classic 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 perfect for pairing with a REDARC Lithium Battery. 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 typically used for lead acid battery banks over 200Ah and lithium batteries over 100Ah. Check the manufacturer’s data for your battery and ensure that the ‘Continuous Current Rating’ of the charger does not exceed the manufacturer’s recommended maximum charging current. For smaller batteries, 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%.*

*large capacity battery banks may require a few cycles to fully charge.

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.

High-Quality 12 AWG Silicone Wire — Perfect for Battery Projects
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
I bought the BNTECHGO 12 Gauge Silicone Wire (10 ft red and 10 ft black) to wire my battery power box, and it has worked flawlessly. BNTECHGO wire has always been reliable for me, and this set is no exception — very flexible, durable, and easy to work with. I’ve purchased numerous other gauges and colors from BNTECHGO, and I continue to be very happy with the quality. I would definitely buy again. Important Note: The amperage rating depends on your wire gauge and your specific application. Make sure to size your wire appropriately based on the current requirements of your project to avoid overheating or damage. Potential Uses: Wiring battery power boxes or DIY power systems Automotive, RV, or marine electrical projects Solar panel or off-grid power setups Ham radio or portable electronics wiring LED lighting and audio equipment wiring Hobby electronics and custom projects Key Features: 12 AWG stranded tinned copper for excellent conductivity Silicone insulation for extreme flexibility and heat resistance 10 ft red and 10 ft black for positive/negative wiring High-quality, durable construction for long-lasting use Flexible enough to route through tight spaces without kinking Resistant to high temperatures, abrasion, and bending Disclaimer: This review reflects my personal experience only and is not professional electrical advice. Always follow proper safety procedures and ensure your wire is properly sized for your application’s voltage and current requirements.

Very high quality for a fair price!
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
I just can't say enough good about this wire! It's really high quality stuff, so much so that I was impressed enough to write another review and buy more! Yeah it's really that good considering you don't see this type of wire around much. Good stuff!

Top notch quality copper and cold flexibility.
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
This is what you need for most 13.8 Volt power pigtails on portable ham radios. They will safely handle over 200 watts in most applications and the wire is flexible in the cold. I have set it outside as a reality check when it was 18.3F degrees and it flexes essentially the same as at room temperature. The copper itself is very fine strands and will likely never fail from normal use flexing. It solders easily with my 40 watt soldering iron. I will not hesitate to buy more if I need it.

Excellent wire! Flexible and easy to solder.
Size: 12 silicone wire red 10ft and black 10ft, Color: silicone wire red and black
This wire is great! I echo the other reviews indicating that the insulation and wire are very flexible and easy to solder. I have had wire that makes you question your ability to solder. Then there is wire like this that makes it so easy!
