bec help please

hey everyone.i am trying to figure out how many bec's ill need to run all of my electronics. could i run my 2 hitec 645mg servos one for summit trans shift and one for my dig unit since they will only be run for a second at the time could i also run my steering servo off the same bec.i will be running one indepent to my winch at 7.2 volts. i know im asking a'lot of questions and i am researching i'm just excited to get this one done.i just dont want to burn up any new parts. thanks in advance

Really need to understand what you are doing with what kind of rig. I can't imagine why a crawler would need to have a trans shift and dig at the same time, but I'm narrow minded in what I consider a "crawler". Tell me more before I decide. I gotta know how you are using the gear shift and dig.

sorry i should have listed what i was running.i am running a 1/8 new bright avalanche.i have an scx10 transmission with a hot racing dig unit on it for a transfer case and a 1/10 summit transmission for the hi and low.that's what i'm running the 2 hitec 645's for and i have a turnigy mg959 on the way for a steering servo and lastly a 3 racing winch.

you could get by on one, but in that case, to be "right" I would be running the pro version or more than one BEC. if you are just running 2s, run power to the servo right from the battery instead of buying another BEC. There are some on here running 6v rated servos at 7.4v, and I have tried it myself, and have not had an issue yet.

For the high power servo doing the steering, it really needs it's own dedicated servo, imo. All those other servos should draw from a separate power source. You can manage either way, but if I was building that rig and I wanted it to be right, there would be more than one 10 BEC.

i was looking at the pro but i cant figure out what the difference is on the bec and bec pro.ill be running 4s due to running a 14.4v dewalt motor.could i run one for the winch and 2 hitecs since are the hitecs arent constant use servos and one directly for the steering servo so it will have its own power source.or would it be best to run a pro for the winch and 2 hitecs and a regular 10 bec for the steering servo

The BEC pro is just a dual channel 20 amp bec(2x10 amp). Sadly the two channels can't be programmed for two different settings.
For you application two 10 amp will suffice. One for the two trans servos, steering and one for the winch.

ok gotcha thank you both for the help.ill order 2 becs and run them all that way.

no kidding!? MIght as well buy the separate bec's then.

[newbiecrawler20]

it would be a whole lot badder asser (its a word lol) if it could be set to different voltages

The other issue with the pro is it's huge ( like AE-2 sized almost) which is a downfall for most.
