cheaper alternative to a ccbec is here

[discgolferlee]

it is not as adjustable as a ccbec but it is adjustable from 5v-5v and provides an external bec for those pesky castle esc's and others.
just figured I would share

Brushless Hobbies UBEC featuring Ultra Low Noise and Adjustable Voltage

When compared to linear UBEC’s, the overall efficiency of a switching UBEC is much higher, temps much lower.
SBEC lowers voltage by quickly switching the current verses the LBEC method of scrubbing current lower, creating heat in the process.
Amps are level throughtout the normal running cycle of a battery unlike LBEC.

Output is 5V or 6V 3 Amp and changed using a selection jumper.

The BH UBEC is the cure for stalled servo’s BEC destruction and provides ample power for today's high torque digital servos.

92% efficiency

Red LED shows correct\normal functioning

Size is 1 ½ inches by 5/8th inch, Weight: 13g

Short-circuit protection

The BH UBEC has metal shielding and a ferrite choke on the output lead significantly reducing electromagnetic interference.

Ultra-wide range of input voltages.

2-6 cells lithium battery pack or 5-18 cells NiMh /NiCd battery packs

Safe power-on with polarity protection assures if the input polarity is wrong, the UBEC won’t be toasted, allowing correction.

3a? Most high torque servo's have a stall amperage above that. does it have a higher peak amperage rating? I might seriously consider this on my SCX10, i need a BEC but the castle is a bit much.

~$10 for a "Output is 5V or 6V 3 Amp and changed using a selection jumper"

Decent ESC internal is about the same. While it can help, I would still spend ~$20 and get a CC 10A BEC.

Granted, the linked BEC does not need the programming cable which will double the CC BEC cost again.

I guess this will do for some people.

[discgolferlee]

yeah the castle ccbec does rock and is better. but I figured I would share for those needing a simple solution
winches, lighting and any other items when you need to relieve some stress off the esc's BEC

I've got a similar one in my little truck and it's just fine. 10A is overkill. These 3A bec's are okay to like ~5A for a while and believe me when I say that at 5A you're looking at stalling a 500oz'ish servo... more than enough current for a servo to either break itself, move a rig or rip itself free from the chassis. Most these things will see is less than an amp over time, I'd have to check but at 10A the wires to the servo would likely fail pretty quickly.

Castle is nice to run >6v. But the castle link is just a USB converter you can buy for like $5.

I was actually going to build my own castle-style bec but I can across the 3a 5-6v ones and I can't even buy the components for as cheap as they are available assembled. (I think I paid ~$4 shipped for mine)

3 Amps is useless in a crawler.

[C*H*U*D]

For the right application this would be a good alternative, but I wouldn't say it's an across the board alternative. I run several of my servos at 7.4v, so that there eliminates it for me.

And I think I have to agree with Grizz on the 3A limit @ 6v for my other servos.

True, in a rally car, Mini Trophy Desert Truck, or something like a Tamiya CC01 type vehicle it would prolly be sufficient.

absolutely, 7.4V will require the castle's programmablity.

3A is the continuous rated limit. much like we run 2s esc's with 3s, 6v servos at 7.4v.. it'll handle much more.. especially the 4-6A it may see for the second or two it might stall in a really bad bind blah blah blah. i'm over thinking this.

i think for most the issue is the casual cralwer trying to get rid of glitches and still running a stock servo, etc.. then buying the castle for $20, and buying the link for $20 is an expense, or just buy the castle and be stuck at 5v since there isn't anyone around here that has a link. (that was my main gripe) or spend $5-10 and get 6v out the box.

now i'm sucked into the hobby enought that after spending >$100 on a servo, spending even another $40 to get the most out of it is nothing.

EDIT: damn money pits. guess it's still better than 1:1 stuff.

I carried those little UBECs for years before Castle got theirs rolling. They are good for about a 250oz servo at most. For lights and stuff, a dandy choice. If you need any steering power above something like a stock traxxas servo, they are just about worthless. For a vehicle other than a crawler, it works fine.

Needless to say that when the Castle BEC came out the UBEC sales went absolutely flat. We went from moving 100s in a year to taking years just to move the last ten units. Now we sell a few thousand CC BECs every year and so far I have seen no products that come close to the value and quality, otherwise I would carry it!


I offer programming for the Castle BECs for people that don't want to buy a link just to up the voltage.

[Robbob]

Ive used plenty of these ubec's in my scalers for the accessories. Theyre small and can be hidden easily.

But can agree, they have a hard time handling what we throw at the Castles in comp trucks and heavy scalers.

[Grizzly4x4]

Hmmm, one of those would be lighter and more convient than the 9V battery I use for lights.

Ok, I can see usefulness of them now.

Will your lights run on 6v?

I'm sure they will if I just change the value of the resistor I have in-line. They might not need a resistor at 6V.

[Olle P]

Same thing at $4.42.
I've found out that at ~8V feed my Hitec HS-7954SH draws ~2A typical and 4A peak, so this BEC should be able to provide sufficient current. The Servo won't be as strong though.

My red tundra had 2 of these running over 8 LEDs. The bigger hassle is routing all the wires neatly.
