Mixed reviews on HK. Is it reliable

[SnoozeDoggyDog]

Hi
I need a BEC  in the SW and Talon builds and was looking at this https://hobbyking.com/en_us/turnigy-5a-8-40v-sbec-for-lipo.html

But the reviews are mixed. Can anyone say they are using one reliably or recommend one?

Thank you.

I've used probably about 10 of these over the last few years and never had any issues with them. My builds don't tend to last too long right enough but it's never been the BEC's fault! :P

What do you need the BEC for?

There may be more suitable alternatives.

For example, that particular item can accept up to 40v.... something tells me you won't have 40v on board lol

The highest voltage battery I use is 4S which is 16.8v fully charged.

On builds that require 12v for the OSD/AP I use this

https://hobbyking.com/en_us/quanum-12v-5a-7-2-25-2v-dual-output-ubec.html

It has two outputs... one of which I put into the OSD/AP, the other I run through this

https://hobbyking.com/en_us/turnigy-5a-8-26v-sbec-for-lipo.html

to provide 5v for my rc receiver.

The Vector does not require any step down regulators as the PSU has them built in... plug your 4S battery into the current sensor/PSU and away you go. It even has 12v and 5v regulators built in so you can choose which voltage to feed your camera and vtx (if they need different voltages)

On my Vector builds, I simply used this https://hobbyking.com/en_us/turnigy-5a-8-26v-sbec-for-lipo.html (same as above) to provide 5V for my receiver.... I don't trust the ESC's built in BEC

What would I do without Blue!

I assumed the vector did the regulation and 5/12v supply but I had assumed it was good practice to feed the servos and vtx with thier own supply. It simplifies things so much for me if indeed it's OK to use the vector.

I'm clearly getting confused. So all you pros who use a vector only use the vector for regulation and supply?

Thanks

The Vector provides filtered 12v and/or 5v for your cam and vtx as required.

Then I use the 5v BEC to power the servos/receiver.

I'm with you now.

The Vector provides filtered 12v and/or 5v for your cam and vtx as required.

Then I use the 5v BEC to power the servos/receiver.

Ah OK. That clears things up a bit. I was going to use a separate supply for the vtx/camera but if you guys are confident using the vector that's fine by me.

Understood re the separate BEC. Thank you again.

The wires coming from the Vector PSU have 2 x red JST connectors and 1 x white JST connector.

the red ones are 12v and the white one is 5v.

There are corresponding JST plugs for these connectors that are labelled cam and vtx.

It's up to you to plug the correct voltage connector into the plug for your component depending on the voltage it requires.

will you be using the camera I sent you? if so, plug one of the red 12v JST connectors into the "cam" plug (the camera can take between 5v-22v). That will leave you with a 12v and a 5v for your VTX. Which VTX are you using?

[SnoozeDoggyDog]

Yeh I'll be using the cam I bought from you and maybe testing a few 12v cams from work.

I'm using an immersionRC 5.8 600mw.

Thanks

Leave the Vector wiring loom as it is then, it's set up for 12v for cam and vtx... your vtx can accept 12v.

Thank you Blue. Sorry for the short responses ... It's bath and bottle time. Not for me, the 2 year old. Priceless info. Thank you
