Hi guys, so it seems like my servos will pull more than 20 amps in hard flight. The regulators I found are 20 amp peak. I like the newest castle regulator. There are other regulators out there but are so costly.
So my question is can I run two in parallel to double the amp usage and provide more battery connections to various ports on my system? Also I figured this could act as a redundant "backup" in case one ever fails.
I know it's probably a dumb question but let me hear your opinions.

I really don't want to spend 100-180 on just a regulator.

Savox HV tail "I'd have to look which on it is."
HV throttle. Again I'd have to look what model number it is.

All HV direct 2s lipo but had over heating issues and want to also add a regulator in the mean time.

Did you write to CC over this??

I would be curious on their reply!

How do you know your servos will pull more than 20A? It seems unlikely to me.

You could run 2 regulators in parallel but wouldn't 2 regulators cost roughly the same as one better regulator??

What did you have overheating issues with? The regulator or the servos? How do you know they were overheated?

I'm running the spectrum 9 rx that has 2 battery plugs and I'm running a 2 cc regulator to each battery plug on the rx

The regulators I found are 20 amp peak.
The CCBECPRO is the way to go, very reliable and inexpensive. You don't need two regs, adding redundancy to one component of a system that otherwise has no redundancy really won't get you much.

Use both wires from the CCBECPRO strategically (distributes the heat, more efficient).

Important! Wire the CCBECPRO to the high ground of your system so as to only pull from one pack (if using multiple packs). You don't want more than 6s-8s going through the CCBECPRO.

Also, 20 amp peak, they can burst higher for short times.

JR 8917s do not like fly-barless. They will get hot and eventually fail. The only way to minimize this is to turn the cyclic frequency down on the FBL controller. They do draw insane current so you are correct that you want at least a 20amp BEC if you go that route, but I am not sure that will help the overheating. You probably don't want to hear it but I suggest you go with a different HV servo that is more FBL friendly, there are tons to choose from.

You could run them on 6v, they will pull less current and run cooler. Still plenty of speed and torque.

All you need is one of these

You can parallel BEC with Batts or any combo of either

Did they fix the BEC issue? When they failed (or you crashed and damage them) they could fail open and the current would get to your ESC and fry it.

Unless they are designed to be connected in parallel, you should NOT wire them in parallel.

Doing so can screw up the control loop response in one or both regulators, causing them to go into an uncontrolled oscillation and eventual failure.

Also, if wired in parallel, due to variations in component values and tolerances, they may not share the load as you expect.

Never a good idea to wire power supply outputs in parallel unless you know for a fact, they were built for that application.

Thanks for all of the replies everyone! I'll try my best to answer everything.
I have not called or emailed castle yet.
I have been told before that all of my servos are pulling some amps.
My servos are heating up to around 170 degrees hovering. I have another topic that discusses this issue. It came down to a vibration issue.
I have not fixed it yet due to being way too busy. But we figured the servo heat was from the vibration and I will lower the servo rates in the beastx plus system.

I am just not sure if the castle bec pro will be enough power output for those jr servos. I've had 8717 servos with no issues at all.

Don, ya know I'm wondering the same thing. Ever since I tried that beasts plus version they get crazy hot. Never had an issue with the standard first versions. I bought a older one to put on there when I'm ready to conquer this thing.

You need a firm thin tape for the beastx, don't use the thick white pad.

Have used and am currently using 8917s and they never get hot or fail in years..at 8.4 volts. I am also using a WR mini BEC and do not have current issues.
If the servos are getting hot, you need to check your FBL unit, the assertion they don't like FBL is not accurate.
To the OP,
Check your FBL unit something is amiss. Also two BECs in parallel will fight each other and cause failures if they are not specifically designed not to do that. To my knowledge, none exist.
The CC BEC says it is good to 12s, it is not reliable at that voltage, and if it fails, I have seen them fail open which mean full voltage that in on the input side runs though your electronics (like 6s or 12s to your servos, FBL unit, etc). Nothing will survive.
My advice is to spend a few more dollars and buy a better BEC that you can wire how it specifies you can, will handle your electronics load, and won't fail.

Did you consider switching to Life/A123 and ditching the regs?

I have gave up on all regulators and have gone strictly HV servos

Working good for the last 3 years with no problems

One less thing to go bad

Lets do the time warp againnn !
