Am I insane for attempting this modular ESC/BEC/CapPack harness?

I have a new Max6 on order with a 4895 1640kv motor for my aging Kraton 6S v4, but with a lot of heavy M2C upgrades. I'm adding even more goodness to my beast.

Anyways, am I crazy for trying this: I want to do some experiments and have maximum flexibility - so i want to create a custom wiring harness (why doesn't anyone sell these!?!?)

So on one end, I have my Max6 ESC. I want to terminate the ESC into QS8 connectors: cuz their the new hotness, aparently. (no real reason actually - could just as easily use some bullet connectors, or Amass XT150s, or some really cool (but expensive) Supra X connectors I recently discovered. I was thinking of creating a "no wire" connector, similar to this: https://a.co/d/0ALe7vm, which is a EC5 to parallel EC5, but I couldn't find any that did a 1:3 split. Interestingly, I found this guy https://a.co/d/4aQiYEy, which is a EC5 male to femle, with a JST lead. That would be promising, for the BEC, but not quite. I mean, I could create my own parallel "no-wire" 1:2 split with a JST female.... but then I got to thinking... and maybe a bit crazy.

I found this interesting thing: a 1:3 splitter with SAE ends (which I will cut off and replace with my own connectors). I think this is used for solar panels. Whats interesting to me is that the 1:3 split is factory soldered/joined - probably very low resistance, and probably better than anything I could do. Whats interesting is this is available in many different gauges and configurations like 1:2 and 1:4. For my application, (6s typical, maybe i'll try out 8s later) I think 12awg should be good - but I'm not an electrician, so please tell me if i'm about to burn down my rc ;-)

I think maybe its better to just draw out a diagram of what I'm thinking of doing:

I realize that for a Kraton 6S basher, I probably don't need a BEC, and definitely don't need a cap pack. What I kinda like about the bec is I could use it to power 12v or 8v 40mm fans, and keep the receiver on the ESC's built in BEC. In any case, it gives options: if I don't want the BEC or cappack one day, its pretty easy just to unplug it.


What do ya'll think - crazy? Will it work? Or is just a big waste of time?

It's kind of hard to tell from this picture but, from the look of this, I'd be a little concerned about the gauge of wires used here. I get the desire for modularity, but this looks like an awful lot of wiring at first glance. I suppose with some work and diligence it can be minimized and made to look neat. I do like the creativity in your approach however. Nice diagram too (y)

The "concept" is interesting..

The gauge of wire from that 3-way splitter (that looks like a 24gauge doodad*) is not going to work.
You will need to produce you own 8 gauge harness if you intend to really make this work.

Also the Cap pack need to be as close to the ESC as possible with minimum resistance..

It's a nice idea..
Good illustration.

But honestly.. more trouble than it's worth.








* FIRE Hazard!

Meaning the thin wires will heat up and melt, causing a short in your Lipos and poof!
There goes your rig burning and smokin' down the dry field of grass..

It sounds like I'm making fun here. But, I'm not.
If you do attempt this and try to run it outside.. Have a fire extinguisher nearby/handy.

the splitter has a bunch of different sizes from 10awg to 14awg: see this link: Billion wealth 2Feet / 65cm 10 AWG SAE Connector Y Splitter 1 to 3 Extension Cable Compatible with Solar Connection and Transfer https://a.co/d/dun6Efe

Maybe I skip the splitter.

Do you think I can squeeze 2 10awg cables into the solder end of a QS8 connector?

And maybe there is room for a tiny 23awg for the BEC. … hmmm

Definitely. I've fit 2x8AWG in there.
 
Upfront, 40mm 12V fans (28mm high cfm type) will break on a basher. If you find a fan that holds up, let me know. I have yet to find one that holds up to jumping.

The concept is a little flawed, but not too crazy. It will be very inefficient due to multiple connectors and just complicate things imho.
A cap pack needs short wires i.e. your entire adapter will eliminate any use of a cap pack.
For additional parallel batteries, the wire gauge isn't sufficient.
You will have a bunch of wires flopping around.
For serial, the stock wiring approach is ideal.

Personally, I wired a BEC directly to the battery connector and power fans that way, you can split out after the BEC. At 12V/2A you can typically run 2 monster fans but I prefer 1 BEC per fan.

The ones on my kraton 8s have survived so far and thats with me landing on concrete half the time. They're just regular 12v fans I got from ebay. I did lose one because of the wire pulling out but that was kinda my fault. Now you have me scared :ROFLMAO:

I'm trying to understand why a cap pack is needed for a max 6 and a kraton.
 
If your confident in your soldiering ability, go for it, but as stated use a decent gauge wire, don’t cheap out on that! And id say make your own connectors is a much better idea. I use xt150‘s and 8-10 gauge wire on my exb with no problems. Good luck

Well, this all started when I was researching people with Kraton's and Max6/4895. I stumbled upon this build log from @Crewchief227 https://www.arrmaforum.com/threads/...east-rich-would-be-proud-of.14349/post-268733 - where it says that he burned out a Max6 due to, well, several reasons, but not having a cap-pack was mentioned. I don't think its required, but it might give piece of mind - but maybe I'm just overthinking it.

I wish I could buy these fan mounts: https://www.arrmaforum.com/threads/fan-mounts-new-design-coming-soon.49534/ - but I don't think any are for sale currently.

So, I found out about Radio Control Power, and I'm thinking about using this fan mount: https://www.radiocontrolpower.com/p...its-45mm-49mm-diameter-motors-40mm-fans-black and maybe even their 40mm fan, which runs at 8volts: https://www.radiocontrolpower.com/p...l-40mm-high-speed-rc-fan-8-volt-plug-and-play

They also have 40x40x10 and 30x30x10 options, maybe running two of those might be more robust?
 
I'm using the 30x30x10 on motor and whatever stock is on ESC just an updated alu fan. Seems to be more reliable. Standard powerhobby fan mount, the clamp style works best.

You definitely don't need one bro. Max6 going bad is super rare and you aren't speed running. Funny enough I was going to link rcp to you yesterday because they have some cap pack adapter stuff too but I didn't bother because you totally don't need it 🤣

Go enjoy your kraton! 😎 👍
