How to install a REDARC BCDC battery charger

[@jonnytacooutdoors]

What about be blue wire? Trying to decide between 1220 and 1220 IGN

[@REDARCElectronics]

Thanks for watching! If you have a car with a smart alternator go with the BCDC1220-IGN, if your car does not have a smart alternator then go with the BCDC1220.

If I connect a solar panel to the dc dc does the panel needs a controller?

[@REDARCElectronics]

Thanks for watching! No, our DC-DC chargers have a built in solar regulator and will take charge from unregulated solar panels only.

@@REDARCElectronics I get an error with the 400W solar panel. All the lights are blinking.

Can I have AGM for main battery and lithium for my camper battery with this BCDC charger ?

[@REDARCElectronics]

Thanks for watching! Providing you are using a BCDC charger that is completely fine.

Hi guys, does the aux battery need it’s own earth separate to the starter battery for the bcdc isolator to work?

[@REDARCElectronics]

Thanks for watching, Jen. Yes the auxiliary battery will need to share a common ground with the BCDC and the start battery. If you have any further questions please be sure to contact our helpful Tech Support Team over the phone.

@@REDARCElectronics Should you run a negative cable from under the hood in order to make that common ground connection? How would the ignition wire be connected?

[@REDARCElectronics]

​@@NomadicIsaac you can run a separate cable for your ground connection if wanting. Otherwise, utilise the chassis as a common ground point - saves that extra cabling. The ignition trigger can be tapped into a source that purely has 12V when the engine is on and 0V when it is off. You might need to locate the fuse-box and see if you can tap into a signal there. Any further questions please contact our Tech Support Team on 1300 REDARC and they'll be more than happy to talk you through this in greater detail over the phone.

When installing in a camper can the black wire from dc just go to the negative of the camper battery

[@wiked1_camptruck]

Hello, great video. With the BCDC 1225d, can a smart charger be connected to the auxiliary battery for shore power with the solar panel connected?

[@REDARCElectronics]

Thanks for watching! It sure can, the BCDC1225D can charge a battery at the same time as another auxiliary battery charger.

[@wiked1_camptruck]

@@REDARCElectronics Thank you. I really like y’all’s products!!!

[@gayashanbc]

Does the BCDC 1225 has the jump start feature?

[@REDARCElectronics]

Thanks for watching! No, if you are wanting to add the ability to jump start your car from your auxiliary battery I’d recommend to add our SBI12 into the circuit. For more information on how achieve this please see the link here -www.redarcelectronics.com/au/resources/chargers-isolators-wiring-guides/bcdc-dual-with-jump-start-feature-the-ultimate-battery-setup/

Wouldn’t putting the lithium battery and or charger in the engine bay shorten the life of them from the heat ? Especially summer time through out the years.

[@REDARCElectronics]

Thanks for watching! No battery likes being under the bonnet of a car, over time the heat from the engine bay would be expected to shorten the life of any battery including lithium. Our BCDC Classic range of chargers have been designed for engine bay install and to withstand the heat.

Regarding earthling this setup: I'm using a portable battery for my aux battery. It cannot be perminant grounded because it's portable. Can I simply run a negative cable from the starter battery terminal along with the positive (fused) that comes from there, with a plug on the end, then the plug connects to my portable battery box. The inside of the battery box I have the other side of that plug which goes to positive and negative terminal junctions. Then the positive junction terminal has a positive running to the bcdc, and the negative terminal has a negative running to the bcdc. This negative terminal can also have another cable running to my aux battery. Then, I can run the bcdc power out cable directly to the aux battery with an inline fuse. It seems like this would work since the aux negative and the bcdc negative run to the same terminal, which then runs to the starter battery negative terminal, meaning they all share the same ground. Please advise.

[@REDARCElectronics]

Hi John, indeed the connection to the Start battery for Positive and Negative will be fine for this type of setup, yes. All the rest of the ground connections will then be made in the battery box to the battery and BCDC, so yes this does make a common ground scenario. As you’ve laid out in your comment, that sounds perfect and how we would expect it to be!

[@jfwatson10]

@@REDARCElectronics thanks, this is great to hear. I'll be making this purchase now that I know this will work.

[@terryyouth]

I am looking for a fire/heat proof box that will fit in there and then use it as a secret compartment as there is no such space inside the car

[@sta8tosporter998]

What about brown wire ?

[@REDARCElectronics]

Thanks for watching! The brown wire is the secondary battery positive connection.
