In my book there is no relay. Why do i need one now?
I have wired a lot of boats in my Marine boat building business and I always put a product called Lana coat on the Crimp lugs and on the boat battery Post
If possible use
tinned wire I I have seen massive welder cables so corroded inside they would no longer perform
Tin the wires upon which you crimp lugs? I wondered if I should do that. I'm using hydraulic crimpers
Does this is not come with wiring? Or does that need to be sourced elsewhere?
the manual sucks trying to wire rk1260 and bcdc 1240 your video shows yellow wire on rk1160 mine big has big orange wire going to solar from rk1260 and dosent show what you do with big yellow from redarc 1240??
great video helpped me so so much
I'm a bit confused...help! This video makes it sound as if I need the relay switch in order to use the dual function of the BCDC. Is that true? My set up is an AGM starter battery, lithium auxiliary/secondary batteries, and solar panels.
Hi BJ, No extra relays of changeovers are required for the ‘D’ model BCDC units; they have all the switching built inside them these days. The RK1260 was for our older, original BCDC1240 units. Any further questions please feel free to contact our technical support team directly.
Id love to put a charge controller on the system
Good tips… but there’s no need to yell at the audience mate 😉
I have been using the same in my motorhome with deep cycle battery, but wanted to upgrade.
Can this 1240 be used with lithium battery? I was told that it couldn't so please confirm. Thank you.
Thanks for watching! The standard BCDC1240 is not recommended for charging lithium type batteries, in that situation it would be recommended to upgrade to either the BCDC1240D or BCDCN1240.
Would it be worth while connecting a switch between the cranking battery and charger so you can turn it off while your not using it?
Hello Steven, thank you for your enquiry. The best thing to do if the vehicle is sitting for a long period is to isolate the entire battery, or use a maintenance charger like the SBC1210 to maintain a 100% state of charge. Alternatively you can install the switch, but it should not be necessary as the BCDC draws such a small amount of current when in standby mode.
@@REDARCElectronics I plan to install the bcdc in the rear of my car, connecting to a aux battery in the trailer, i wanted this flexibility so i could run the bcdc with or without the trailer depending on the type of trip. I figured it the bcdc wont be utilised 90% of my driving time, and logically a switch to turn it off would help uneccesary draw, but if the standby draw is very low when an aux battery isnt connected, then thats fine by me. thanks for your feedback.
I have had a bcdc 1225 installed by ARB. It has been installed 1.5mtrs away from the battery. Is that ok? I did bring that up to them and the answer was it will be to hot to install it near the battery which is in a under tray tool box. I believe the engine bay us much of a hotter spot and they are ok to be installed in the engine bay. Unfortunately it has been about 3 years since the install. If I have some type of support I guess it is worth getting them to re install correctly. It does seem the battery is not charging the way it shoukd be in guessing this might be why

Is there any separate display or Bluetooth app for this controller ?
Thanks for watching! The BCDC range does not have a display or Bluetooth compatibility. If you're looking for that feature, we would recommend checking out the Manager30.
I know this video is two years old but hoping you'll be able help out a guy in the US.... My van does not appear to have a smart alternator (will check thoroughly before installing). In the US most advice seems to be that the relay is necessary for smart alternators and/or long cable runs (trailer battery) where running a long ignition wire may not work. In this video it appears that the relay kit is also necessary for anyone wanting to use solar AND starter battery input to charge the house battery. Is this the correct understanding?
If you have the current BCDC1240D, the RK1260 Solar relay kit is no longer required.

The directions say to connect directly to the house battery, not the alternator. My concern is that the limiting factor would be the vehicles battery charge rate, not the alternator output. 40amps seems like a lot to ask of a vehicles charge output. I have a Tundra w 130amp alternator BUT there is no direct path from alternator positive to house battery positive so the 40amp draw will have to come thru the fuse block as intended to be charging current for the house battery.
Hi Chris, thanks for your comment.
How it would work is when the BCDC is pulling full current out of the start battery (40A), the load on the circuit and alternator will be higher as the start battery requires more so it will be able to provide the extra to keep the battery charged and the BCDC outputting fully.
Once the BCDC moves through its charging stages and the need for current drops, the alternator won’t have to supply so much current, so the output could drop if required.
This will especially be the case with a vehicle that has a smart alternator - they vary the voltage as required according to the load on the system.
If you have any further questions please feel free to contact our friendly Tech Support Team on 1300 REDARC.
I have an impression this guide is dated and not up-to-date, as latest marketing material speaks about Charger actively balancing carving from solar and alternator at the same time with ECO bias to all solar power available - it renders the RK60 relay obsolete
Thank you for viewing, and for your question. You are correct that this video does not relate to the current range of REDARC BCDC battery chargers which do also feature solar charging capability.
When would you use 15 or 15.3 voltage?
Thank you for your message. When your battery specifications require it, many calcium and lead acid batteries require this higher voltage in order to charge correctly.
When you say wire all grounds to the same place (chassis), how is that possible when the BCDC charger is in my caravan beside the AUX batteries? That would mean I could not disconnect my van from the car as it would not be common with the car then right? I am new to this stuff, but would it not be better to run the BCDC earth via Anderson plug from the van back to the car chassis or starter battery?
Thanks for watching! When wiring the BCDC ground you will want to make sure the black wire goes to common ground, it only needs a common connection to the car when its trying to charge from it (e.g when the caravan is connected).
If you have any questions on this please don't hesitate to give our technical support team a call on 1300 733 272 (1300 REDARC).
@@REDARCElectronics Oh of course, silly me. If the caravan is disconnected, it dont need the alternator lol. I already ran a twin core 4B&S cable from starter bat to Anderson plug, but it seems I dont really need it now, if I am to earth to the caravan chassis as shown in manual instead. Is there any benefit of doing both... like earth the BCDC to both caravan chassis AND starter battery?
Please import the manager 30 into the USA.
Thanks for watching our video and for your comment, Richard. As for the Manager 30 being made available in the USA all we can say is watch this space.

I have 100 ah battery (start) and 100ah (auxiliary) and handy 240ah lithium and solar panel with 200w.
Should i go for redarc 25a or 40a or 50a? Or it doesn’t matter?.
I want the fastest one
Hi Hussam, thanks for your comment.
One thing we need to consider is not to overload the alternator in the vehicle with too many charging systems; so will need to take a measured approach to this.
How is the Auxiliary battery being charged? If it is via a BCDC already, then we might consider at most a 40A BCDC unit for the Lithium battery to not overdo the system. If the Aux battery is being supplied by a battery isolator however, we could then consider a 50A BCDC for the Lithium as there would be slightly less load overall.
See how you go and if you need to have a more in-depth chat with us, please give our Tech Support team a call on 1300 REDARC
Seems though the six flashes is common but not addressed.
Hi there, thanks for your comment. The 6 flash code on BCDC refers to either an Over-Voltage from a Vehicle or Solar input OR it can also mean Reverse Polarity, usually from your Solar panel. In a lot of cases, the 6 flash may occur when a Solar panel that is over the 32VOC maximum is connected to the charger or if a new connector has been setup and the positive/negative wires have been mixed around
@@REDARCElectronics Hi so the panel was putting out 22 volts, day was clear and panel in full sun, the ground wiring has been split into 3 and polarity is correct. All joints are soldered joints. Charging from the car to the redarc is working as it should.
@@kman6482 What would be good is to power cycle the BCDC and see if this will clear - disconnect all connections to the charger including Input, Output and Solar wiring, leave all down for 10-15 mins, then reconnect up beginning with the Output and Solar wiring first. See from there how you go. If no good from there, it's recommended that you call REDARC Tech Support on 1300 REDARC for further help.
@@REDARCElectronics Found the issue. Cord supplied with new solar blanket crossed at 1 Anderson plug. Need I tell you which brand, you may have an idea.
I am going to have solar panels fixed on the roof of my camper van which will assist in charging my auxiliary battery via the REDARC BC-DC system. If I choose to charge my battery with an additional solar panel at a campsite, do I need to do this via the REDARC module or can I connect the second solar panel directly to the auxiliary battery via an Anderson plug?
Hi Gary, thanks for your message. The best option to connect an additional panel is through a dedicated Anderson plug input for a Solar panel. In this case, you will need to connect this Anderson in parallel with your other solar panels on the roof (all positives together and all negatives together).
If you were wanting to try a different method, you can use a separate solar regulator and wire the panel directly to the battery if required too. Although you will have the BCDC and separate regulator fighting for who has charging priority
.
@@REDARCElectronics Many thanks for this. My thoughts were that if the van is parked in shade, which it will be, I wanted to keep the auxiliary battery charged with a independent standard separate solar panel. Do I have to keep the REDARC module connected to the auxiliary battery when parked, or can I disconnect it from the system and have the battery only charging from the separate solar panel?
@@garydurandt5737 You can disconnect the BCDC if you are wanting to, but it does draw very low current from the Auxiliary battery anyway, so shouldn’t be too bad in the long run anyway. It’s less than 8mA. Have the separate panel keeping the battery topped up and it will work nicely
Does the device become hot while in use? how hot?
Thanks for watching! The BCDC will get very hot when under full load as it is a fanless design that utilises its heatsink to dissipate all heat from the unit passively. This is part of it's normal function and shouldn't be a concern.

Hi,just brought a redarc elite brake controller,should there be any lights on the control knob,while I'm not towing?
Thanks.
Hi Lu, thank you for your message. As a starting point try watching this handy video and if you have any further questions please contact our Technical Support Team on +61 (08) 8322 4848. ruclips.net/video/b06BxqyBFWc/видео.html
Nope. But you can push the knob and it’ll have a blue light come on. Normal non towing operation has no lights on.
Scott R if u don’t unhitch your car from the caravan ,the control knob in the car is light up blue 🚗
jenice currie, yeah but he asked if there were lights on it when NOT towing.
I have a 2013 Mercedes Sprinter Van with a factory installed dual battery package. should i connect the BCDC to the start battery or to the auxiliary battery ?

@@RainBoxRed He's talking about the new battery, not the one provided by the vehicle manufacturer.
Redarc do you have a part number for the specific lugs used in this video at the 2:55 mark as these allow more thread and a much greater contact
Hi Adam, thank you for your message. The lug we use in our FK40 and FK60 is a CTL10-6. Any further questions please be sure to contact our Technical Support Team on (08) 8322 4848.
Looks like MTA part number 1708250 - not as easy for DIY install as the closed-barrel lugs in the kit.
If my car has a 100Amps alternator, is it possible to use 2 chargers in parallel to charge LiFePo4 batteries faster (with double the current of a single charger at the battery poles) ?
Hello, thank you for the enquiry. You can wire up to 4 BCDC in parallel, assuming the alternator can supply the required current. Its hard for me to be 100% sure with your vehicle as there are a lot of variables in this question. My guess would be 2 x BCDC1225D’s or 1 x BCDC1240D would be the max you could run, please confirm this with a local Auto Electrician. If you would like a recommendation from REDARC for a local installer please feel free to call 08 8322 4848 and speak with one of our help desk staff.
@@REDARCElectronics Thank you for your confirmation and this tip: www.redarc.com.au/how-to-connect-bcdc-chargers-in-parallel
My Mitsu L200/Triton has an 90Amps alternator (non-smart), but nevermind, the goal is to put solar panels to work and deliver most current. I bought BCDC1240D and newer BCDC1250D.
I was under the impression the solar panels could connect direct to the Redarc.......also, i see folks using 100 amp fuses.....I'm just jum ping in to all this with no electrical experience.

@@REDARCElectronics Stephen doing that doesn't help inform those of us reading through the comments hoping to glean additional information.
Hi @@oneeyedphotographer,
Stephan’s question related to the new model, the BCDC1240D Dual Input In-Vehicle Charger, whereas the older variant required a relay to switch between vehicle and solar inputs (the BCDC1240).
The 100A fuses would most likely have been a reference to our Ultimate Dual Battery Setup, which allows for backup jump starting from you auxiliary battery and charging through the BCDC: www.redarc.com.au/bcdc-dual-with-jump-start-feature-the-ultimate-battery-setup
Thanks for watching!
The termination used on the butt splice shown at the start of the video is terrible, is as a professional, I would be ashamed to show that.
