Tech Tuesday How to Install a BEC

***WATCH IN FULL 720HD ***
On this Tech Tuesday video I give you a quick guide on how to install a BEC or Battery Eliminator Circuit. If you do not know what this is, it pretty much eliminates any possible circuit that is impeding the electronics to function at their max capacity. But thats in the crawler side of things. For an aircraft this eliminates the power going to the motor when the battery is low, allowing you to safely maneuver your aircraft to land safely. Hope you guys learn a bit from this video and are enjoying the Tech Tuesday Series.

My second visit and it is still the best video on how to install a ubec. Brilliant

[@RCInMotion]

Terry Murphy thanks for the awesome feedback !!!!

[@markozsky]

yeah...tq sir..simple explaination.

[@Cmorep3]

this video also serves as a reminder to check your batterys In your smoke alarm. thank you for the good info in this video.

[@RCInMotion]

Cmorep3 hahah that's my lipo smoke alarm. I keep it next to my lipos and as I started filming it kept beeping lol.....

[@OGPAPERBOY77]

Holmes Hobbies RX Bypass is needed and you wont have to remove the red wire from esc and it will only give the bec power to the servo and not the whole receiver

[@StillDown04]

I did learn because I only have a 2 channel receiver but now I know I can put a bec on bind ! And I subscribed to your channel

[@S5UPERCHARGED]

Video helped. I was wondering about having two power sources going to my receiver, now it all makes sense 👍😀

[@RCInMotion]

Glad I could help

[@rcbustanut2057]

So, if I understood you correctly, the ESC provides power to the receiver via the 'Red' wire. So, in theory, removing the 'Red' wire & plugging in the BEC into the receiver allows the BEC to power up the receiver, which also sends power to the servo. So now the ESC can focus on only sending power to the motor. I take that this also results in a cooler ESC.

[@RCInMotion]

Lord Bustanut hypothetically in a way yes, because it splits the voltage to where it’s needed putting less strain on those electronics that work more or less. For example if the servo needs more input you can program it so that the voltage is focused on the servo but doesn’t take away from the power. Always remember some ESC are preprogrammed with a BEC to balance the distribution of power, usually this BEC is set lower to manage the power input. But having a separate one can be useful in some applications. Hopefully that helps...

[@rcbustanut2057]

@@RCInMotion aaahh, ok. Thanks for the quick reply. I have a traxxas rustler xl5 2wd. I picked up a gyro for it. I wanted to make sure I wasn't drawing too much power from the ESC

[@pwrofgrayskull]

This video has helped me a lot, thank you! Subscribed. 👍✌️

[@terrymurphy562]

Fantastic and very helpful video. Nicely and thouroughly explained.

[@charlestreibley9904]

Please note the Track Star TS3T with matching receiver you must use a Y connection and plug the BEC and the servo into channel 1 only, no other slot or combination will work. I tried them all. The symptoms where that the steering servo would work but no forward or reverse and the ECS beeping like it has not connection.

[@robertosamson1951]

[@allenproman1071]

thank you very helpful.

[@kkhalifah1019]

That thing costs US$20. You know... for just US$2 or so, you can buy a DC-DC regulator (which is what a BEC really is) that you can use to dial down your battery voltage to whatever voltage that suits your servo..? Wires up in exactly the same way, but fully adjustable yet a hell lot cheaper than your full-blown 'programmable' BEC..

[@mikec.9979]

Can I use 8.4v nihm with cc bec? never used one but I need it also not too comfortable with lipos. Thanks good video even today

[@RCInMotion]

You can use it as long as you program it on castle link. Should work fine as this is a voltage regulator in a way. Hope that helps.

[@thatsmyrc]

If i dont use a esc in some of my custom rc conversions builds (dozers etc) And I just run the reveiver as esc for those servo channels.. does that mean the reciever draws what ever dirrect power straight from battery voltage? So lets say i have a 6v battery then the receiver is kicking out 6v to channels? reason asking is I want too run a few of my channels on 6.8v too my servos running 360 for gear drives for max voltage to that servo.. do I just then add a bec or will that effect across the board channels as well. I dont want too burn up my axuonix linear servos that only run at 6v...make sence lol?

[@ArmanRC]

thanks for sharing the tips

[@AcidTechnoMan5000]

OMG you're one of those guys. Those guys that can actually handle that smoke alarm battery fault beep, every 1 min from here to eternity. My neighbor across the street, you could hear his beep in the Summer with the windows open, FOR 2 FUCKING YEARS. If you can handle this for more than 5 minutes, you're fucking NUMB!!!!

[@RCInMotion]

Acid Techno Man you made my night hahahah

[@adrianau4246]

How can I use something like this to power my flashlight made for a drone but it’s meant to use it’s own 2-3s battery & my drone already has a big 6s battery max 25.2v how can I set this flashlight up to that? & just have a connector to disconnect when not needed from my 6s battery to the flashlight… thanks!

[@RCInMotion]

You’d connect it to a male connector just how you would on a FC of your drone. Power goes to your power source but instead of connecting the wires to your FC connect it to your Flashlight and program the BEC to the voltage needed. All can be set via the app on a computer. Hope that helps.

[@adrianau4246]

@@RCInMotion do you know much about cc/cv drivers? Someone said to use that since it’s adjustable to meet my 12v needs?

[@RCInMotion]

@@adrianau4246 not much but yes these BEC circuits are adjustable and it makes it a perfect match for any application. These will keep the constant voltage to which you program them.

[@westonpaschal5078]

Great vid. I just did this. It’s got issues. My set up is a Hexfly ESC from a redact gen7, and an rc4wd 3 channel with a savox wp0231 servo. It has a light kit but plan for a winch later. I put the BEC in the b/c channel, used an extension to cut out the signal from the esc. When I hook up the battery, the servo comes on as well as the lights but no throttle until the esc is turned on. I have steering either way. Is this normal or is something not right. Any help is appreciated.

[@anthonythompson4718]

Thanks for this very helpful.

[@ZjednoczonyWroclaw]

Sejsony Tiger?

[@SuzukiKQ700owner]

Is there a way to add more power to your servo without frying the receiver? My receiver can only handle 6v, so it would fry if I added any more power to it using a BEC.

[@RCInMotion]

To be honest if your RX bec is 6v already you should be able to run it no problem. You may want to program your RX if it’s programmable. If not bring your ESC BEC down as well.

[@footballflickerz1567]

If my esc has no Bec and I add an external one do I still cut the red wire

[@RCInMotion]

Don’t cut it just eliminate it just tape it to the side... you want to be able to use that Esc in the future if you decide to.

Hey I need help I installed a bec on my boat I'm building and hooked up the batteries and the brown wire melted can you please help me figure out what I did wrong please and thanks

[@PatisserieRoyale]

i checked with a multimeter the ubec voltage connected to the esc , is it normal that it's 7.27 instead of 7.4?

[@tobydyes]

Double the voltage plug 2 red wires into the receiver and the both run 6 volts receiver is getting 12 volts

[@batuhancaglayan9689]

@RC In Motion Hello, thanks for good explanation, i have not enough information about these topic, So that, i have a basic questions. I have a esc which has 5.8V 3A bec, i connect this bec wire to my 3 channel receiver and it works successfully. Last week, i bought new esc (6.1V 3A SBEC), i connected to my receiver. Firstly, it worked two times and after that, it stoped working. Now, second channel of recevier is not working. I think that, it damaged. I need a external bec, am i ? You disabled red wire and you connected 2 wire to receiver (one is bec output wire, other is esc wire). I want to connect only one wire to my receiver. Can i disable both black and red wires. And can i connect external bec red and black wire instead of them. does it correct setup ? Please help thanks.

[@BLOVECU]

great video. explains it very well. but the l in soldering is silent.

[@JesusMoreno-vg7if]

Is the bec only for climbers

[@RCInMotion]

Jesus Moreno not at all you can install a BEC on any application all depending on your use. The bec is to route the power where it’s needed. Say you have an esc but a poor BEC, you can simply install one for better performance. We use it on climbers to increase servo performance, but it serves many purposes.

[@obee69242000]

witch way do you plug it in for the correct polarity

[@RCInMotion]

Big will S. Just like a normal servo. On your third channel or if you have a bind channel you can connect it there,

[@PatisserieRoyale]

hey , is it normal after installing the ubec on my axial scx10, when i plug in the battery, i have steering working without switching on the esc ?

[@RCInMotion]

Azmi J yes it is completely normal the power is routed to the servo for max output. Switching on the esc will then power your rig but in term what the bec is doing is maximizing the power to the servo so you can get the torque you need. You can always tune your BEC via the castle creations USB link. Hopefully that answers your question

[@bec6302]

*Bec*

[@theirishaxe9405]

Hey man I need to install one of these into my arrma notorious I put a 8.4v servo in it how do you get this bec to put out exactly 8.4v? And where can I get one thank you!

[@RCInMotion]

John Smith you can achieve that by one of two things. Adding an additional source of power for the servo like a smaller lipo or programming the voltage within the castle creations software via Castle Link. Hope that helps

[@NCMOUNTAINSbackyardRC]

NC MOUNTAINS ❤. 👍👍

[@AJDRAGON01]

Hi, I do not know why they call it a BEC or Battery Eliminator Circuit, because that is not what it is or does. What it really is, is a ESC Bypass Circuit, a BEC does the opposite of what this does. A BEC eliminates the need to have an extra battery pack to power the receiver, nothing more nothing less. Personally I would just buy an extra little battery pack for $10 to plug into the receiver.

[@_beastmode_rc]

Can I use that bec on 6s?

[@RCInMotion]

Traxxas_monster channel if it’s rated for 6s yes you can, always read the label on the Max input and you should be good. Hope that helps.

Your soldering is atrocious. It seems to me that most people solder their BEC directly to the battery connector while replacing the old Deans connectors at the same time. Not that your way won’t work, it will, but I would never suggest cutting factory ESC wires.
